I need something like this for my office and storage on the 4th floor,
but
needs to handle more than 200 lbs.

Haven't seen the video but make it with pieces twice as thick.

OK, I saw the video. If 4 ropes are 200 pound test each, why is the
weight limit 200 pounds. Don't put all the weight on one corner.

It's the old "no chain is stronger than it's weakest link" theory. I
wouldn't want to test it. Just get some better rope.


I have seen some 1/4 inch Dacron rope listed as 900# berak strength. The 4
ropes should be good for over 1000# of lift. The weak point may then be at
another point.
