Securing TE to the bench?
What's a straightforward method for attaching equipment to the bench so it
won't "walk" off? (This is my desire, so let's not discuss why or why not please.) I have 3/16 steel cable and ferrules for making lanyards. But how best to attach the lanyard to, say, an HP 34401 bench DMM or Tek 2465? Not adverse to drilling the case as long as there is strength to be had and can limit the possibility of shorting. Thanks. |

The front and rear "bumpers" are thicker than the rest of the case so you can't slide it out without disassembly. There are no bottom screws so the trick people used to keep VCRs from vanishing off AV carts won't work. If you don't mind equipment buthery there are plates for adding security cables. Most glue on, some can be screwed or riveted into place. If you install them nicely, you probably won't completely trash your resale value.

The ones at school were, IIRC, either strapped to the bench (e.g., scope's
tilting handle plus cable clamps), or using rack mount bits and angle brackets (e.g., the bench DMMs are half rack width with mounting holes on the sides, or something like that).

If so, then what everyone else has said. For earthquake resistance or for a test bench in a vehicle, where they need to be mechanically secure but not at all proof from thievery, then you want a different approach. In that case I'd run a nylon strap over the top of each one and cinch it down. You can get straps & buckles & whatnot at REI and similar outdoor stores. -- Tim Wescott Control system and signal processing consulting www.wescottdesign.com |

Not adverse to drilling the case as long as there is strength to be had and can limit the possibility of shorting. Open the unit bottom, take a half-shell type pipe hanger, mark, drill holes. Watch the debris and that the drill bit won't tear up anything. Deburr carefully. Screw on with small short carriage bolts with the threads towards the inside. Close unit and loop locking cable through there. If concerned that they might take the lid off and undo the whole chebang use hardware for highly non-standard wrenches or rivet in the half-shell. They could still drill that out but if someone is this determined they'd also cart away the whole lab bench, along with the vending machine in the hallway and the ATM across the street. Loops work as well but like hooks they only have a single fixation point and thus can eventually twirl themselves loose. As an added measure, if someone tugs on a unit and pulls the rope taught, let a switch activate an MP3 player connected to a speaker that plays this: https://www.youtube.com/watch?v=-1FvF69xV3k Followed by the harmonica theme from "Once upon a Time in the West", after which the thieves will probably come running out screaming :-) -- Regards, Joerg http://www.analogconsultants.com/ |

A new neighbor came over one hot summer Sunday complaining that he had locked himself out of the house -- along with his wife and newborn son. Apparently, the locksmith (in addition to wanting a fair bit of money for a house call on Sunday) wouldn't come to the house until "after the game". It took me a bit more than a minute to figure out how to get into his house -- without leaving any visible signs of damage/entry. The look in his eyes was priceless: "THIS is my new neighbor??? Perhaps I'd best keep on his 'good side'!" Locks keep honest people honest. |

Most people don't think about how to get around "security" measures -- which is why they are reasonably effective! I.e., the *initial* impediment tells them, "you shouldn't be doing this" -- and, they comply! But, if you are *truly* trying to protect something, then you have to take into consideration *every* adversary. Including those that would "invest" *more* than the (apparent!) value of the item being protected (perhaps because they evaluate its value -- and their costs! -- on a different scale from yours) A friend is actively involved in disaster preparedness for state and federal agencies. He always delights in how "well" the drills, full-scale exercises turn out! I gently remind him that the folks involved in those drills *want* them to work out well -- even the "volunteers" posing as victims, etc. "Want an idea of what a *real* scenario will likely be? Put a pile of cash in the room (i.e., the "scarce resources you will be metering out in a disaster) and open the event 'to all comers'. And, make sure you've got live ammo in your weapons -- cuz some of the self-invited participants likely will!" |

Sun Microsystem's desktop kit used to have a small (1cm) cube of metal on the back with two holes drilled through the center. One hole allowed you to screw the cube to the rear case (the back of the hole was a smaller diameter to be clamped by the screwhead). The other hole allowed you to pass a steel cable through the cube, which when fitted, covered the screwhead so you can't unscrew the block. I think the block fitted in a slight recess in the case so you couldn't twist the block itself to try and unscrew it (a locknut would do the same if there was no matching recess). IBM just made the hardware larger than the door. ;-) |

Ah, you mean "Kensington". A brand-name that's become a standard. They look very feeble to me. I never tried yanking on one to destruction, but I find it hard to believe it wouldn't simply snap the T-piece off the lock. It doesn't even take that sort of effort! Most of the "locking devices" that fit into the Kensington "slot" are very insecure -- easily "picked" with a metal shim, etc. Plastic cases with Kensington slots usually have a thin piece of sheet metal on the inside to reinforce the "slot". But, it's still relatively easy to grind away the plastic *and* that thin bit of sheet metal (assuming the vendor hasn't decided to save a few micropennies by eliminating it -- "locks keep honest people honest"). The laptop I fixed two days ago had an aluminum (?) case. It would have taken all of 60 seconds to grind *around* the slot with a Dremel (TmReg) and a small diameter "ball" milling tip. And, once free, clean up the hole with the same tip. You could then LEAVE the clean hole in place without fear of exposing the innards of the device as there is usually an inner barrier to prevent the lock bits from infiltrating the case! Sun Microsystem's desktop kit used to have a small (1cm) cube of metal on the back with two holes drilled through the center. Actually, more of a prism than cube. A hole drilled "left to right" (or top to bottom, depending on orientation) through it. Then, another *recess* (square hole) cast into the piece normal to this into which the fastening screw is placed and secured to the case. One hole allowed you to screw the cube to the rear case (the back of the hole was a smaller diameter to be clamped by the screwhead). The other hole allowed you to pass a steel cable through the cube, which when fitted, covered the screwhead so you can't unscrew the block. I think the block fitted in a slight recess in the case so you couldn't twist the block itself to try and unscrew it (a locknut would do the same if there was no matching recess). As there is typically a plastic "skin" over an internal metal structure (which receives the screw's threads), unless the lock block is secured *well* (i.e., screwed down TIGHT), the slop between the plastic case and inner metal frame is often enough (with inward pressure) to allow you to rotate the block. Of course, no guarantee that the screw head will rotate *with* the block -- you could end up just spinning the block 'round and 'round (with cable in the way while you are doing this!). But, as with the Kensington approach, a Dremel can easily grind through the little bit of metal "above" the cable to turn the hole into a *slot* -- from which the cable can readily be extracted. The locking block can then be removed and discarded (if you don't want to be reminded of your transgression). Or, replaced with another "borrowed" from another piece of kit (the block and screw aren't typically needed to hold the case closed; their function is largely anti-theft). Locks keep honest people honest. As the OP still hasn't indicated the level of threat that is faced (and attacker's motivation), all this is just speculation. |

Perhaps only hire those that don't need to steal to support their drug habit. It was the @#$%^&*( engineers who used to raid production floor work benches, instead of taking the equipment assigned to them when they had to go into the field. It backfired once, when they swiped my 300 MHz Tek 2465. I got the new 400 MHz Tek 2465B they were supposed to get. They demanded that I trade with them. I told them I would break the fingers of anyone who took it. It was still on my bench when I left, a few years later. There are less draconian means than a safe to keep "honest" people honest. The Kensington locks work. OTOH, since it's a company resource, I can't tell others not to use the equipment on my bench. Tools I try to lock up since they just get scattered to the wind. Anything else can be taken, though I would prefer to be asked first. |

don't need to steal to support their drug habit. This is my business workbench/equipment in my home. Some homes have been burglarized recently: smash a door glass, open the door, march the proceeds out to the driveway (where a van has been waiting with rear doors right up against the house) and load up everything. |

Wouldn't they also take the *bench*? (as has happened here, recently, with homes being "cleaned out"). Perhaps a wiser approach might be to affix a sticker to each piece of kit offering a reward for its return! Then, if it ends up in a pawn shop, etc. SOMEONE has an incentive to contact you. Often, just having contact information on the item can result in a friendly call... OTOH, if they feel inclined to take your OBVIOUSLY VALUABLE (why else would it be so effectively SECURED?) equipment, it is unlikely that they will take extra precautions to *protect* it as they try to remove it (they probably wouldn't know HOW to "be careful" with it). So, any recovery would likely be of DAMAGED kit! |

I recall the fire extinguishers on the school busses I rode all had big orange bumper sticker sized stickers on them that said "STOLEN FROM ROBINSON BUS" or whatever the company was called. I always found those funny quite entertaining. |

Hillarious. Why not just put stickers on stuff that says "don't steal, it's wrong"? "Do not remove, under penalty of law" on the stickers? I was looking for a tile saw at one of the (many) pawn shops here some months ago. Seeing the variety of "stuff" they had up for sale, I thought maybe this would be a great place to get rid of some of my test/development equipment (logic analyzers, freq counters, waveform generators, programmable power supplies, etc.). Of course, I was sure the prices on the devices for sale there had to exceed the $$$ they were willing to "loan" to the original owners. But, by how much, I was not sure. (I was just looking for "anything" to save me the hassle of eBay-ing it all -- how many folks want to pay to ship a heavy piece of kit?). When I asked the guy at the counter, the first question out of his mouth was: "Is it from a business?" Technically, my answer would be "Yes" -- and he just shook his head, "No". Apparently, the inventory control tag -- or any other "formal" reference to business ownership -- is a red flag for them. Had they been marked "Spehro Pefhany" (even if ENGRAVED nice and pretty), they would have had no problem with them -- just like most of the other stuff that was displayed for sale. I guess they figure folks won't bother checking serial numbers on whatever (tile saws, televisions, computers, etc.). Or, that it's enough of an effort that they can "reasonably" ignore that. OTOH, an inventory control tag that says "Burr Brown", "Texas Instruments", "Local University", etc. is too much for them to bother with -- even if you can demonstrate legal ownership of those items! Amusing as most of those are easily removed. But, the guys burglarizing a home are typically looking for something "generic" to flip -- a TV, tools, lawnmowers, etc. *NOT* something that they are going to have to post on eBay for a buyer! Thankfully, I know enough folks that I could find good homes for all of the kit that I was shedding, at the time! The *next* batch I will be sure have no inventory control tags if I revisit a pawn shop! |

You have to assume most folks are NOT coming back for their "escrow"... so, they have to gamble as to what they can sell the items for, "quickly" (as they have limited space to warehouse the stuff). I'd be curious as to how much they "lose" fencing stolen merchandise (confiscated by police) but assume it probably isn't that much! Too many places an "individual" would have to check in search of *his* stolen goods (do you have S/N's of everything you own recorded?). Neighbor was burglarized and police "made out a report" but were pretty frank in saying the chances of any recovery were zero! |

Ah, you mean "Kensington". A brand-name that's become a standard. They look very feeble to me. I never tried yanking on one to destruction, but I find it hard to believe it wouldn't simply snap the T-piece off the lock. It doesn't even take that sort of effort! Most of the "locking devices" that fit into the Kensington "slot" are very insecure -- easily "picked" with a metal shim, etc. Plastic cases with Kensington slots usually have a thin piece of sheet metal on the inside to reinforce the "slot". But, it's still relatively easy to grind away the plastic *and* that thin bit of sheet metal (assuming the vendor hasn't decided to save a few micropennies by eliminating it -- "locks keep honest people honest"). The laptop I fixed two days ago had an aluminum (?) case. It would have taken all of 60 seconds to grind *around* the slot with a Dremel (TmReg) and a small diameter "ball" milling tip. And, once free, clean up the hole with the same tip. You could then LEAVE the clean hole in place without fear of exposing the innards of the device as there is usually an inner barrier to prevent the lock bits from infiltrating the case! Sun Microsystem's desktop kit used to have a small (1cm) cube of metal on the back with two holes drilled through the center. Actually, more of a prism than cube. A hole drilled "left to right" (or top to bottom, depending on orientation) through it. Then, another *recess* (square hole) cast into the piece normal to this into which the fastening screw is placed and secured to the case. One hole allowed you to screw the cube to the rear case (the back of the hole was a smaller diameter to be clamped by the screwhead). The other hole allowed you to pass a steel cable through the cube, which when fitted, covered the screwhead so you can't unscrew the block. I think the block fitted in a slight recess in the case so you couldn't twist the block itself to try and unscrew it (a locknut would do the same if there was no matching recess). As there is typically a plastic "skin" over an internal metal structure (which receives the screw's threads), unless the lock block is secured *well* (i.e., screwed down TIGHT), the slop between the plastic case and inner metal frame is often enough (with inward pressure) to allow you to rotate the block. Of course, no guarantee that the screw head will rotate *with* the block -- you could end up just spinning the block 'round and 'round (with cable in the way while you are doing this!). But, as with the Kensington approach, a Dremel can easily grind through the little bit of metal "above" the cable to turn the hole into a *slot* -- from which the cable can readily be extracted. The locking block can then be removed and discarded (if you don't want to be reminded of your transgression). Or, replaced with another "borrowed" from another piece of kit (the block and screw aren't typically needed to hold the case closed; their function is largely anti-theft). Locks keep honest people honest. As the OP still hasn't indicated the level of threat that is faced (and attacker's motivation), all this is just speculation. You don't understand how a Kensington lock is intended to work. The point is not to keep a laptop from being taken by brute force. The intent is to require that enough damage be done to the laptop in the process that no one will want the unit. Grinding a gaping hole in the side greatly reduces any resale value of a laptop which is already not much to begin with. Used laptops aren't worth much and one with obvious case damage is nearly worthless. That said, lab equipment is a different animal and is worth a large portion of its original value. A hole in the side might reduce it some, but there would still be plenty of value to make it worth stealing even if it requires doing some damage. -- Rick |
