What is the difference between sgl cyl & dbl cyl? -- Thanks

One is a seagull cylinder and the other is a Double Stuff Oreo
cylinder.

With double, if someone breaks in through a window, they can't unlock
the door to carry things out.

Also, if you have windows in that very door, they can't break the
glass and unlock the door.

I put in double when I had an apartment, because the fire escape was
accessible to others. *But I never locked that deadbolt when I was
home, because I didn't want to depend on finding the key if there was
a fire, or if I were in a hurry. *Even with various roommates, it was
easy to get them to follow the same rule. *(and they weren't very good
learners otherwise.)

Medco has a double cylinder deadbolt that uses a captive key inside. It has
a handle on the inside key so it looks like a lever, but can be removed by
inserting the regular key into the outside cylinder and pulling on the
handle of the captive key. This way the inside key can be removed for extra
security when you are absent for a time, but other times it acts as a single
cylinder deadbolt.- Hide quoted text -

This sounds like a lock for those that enjoy playing the odds -

You'll settle for a single cylinder deadbolt for short excursions out
of the house, but opt for a double when gone for extended periods -
"extended" being in the eye of key-holder.

Yeah, it sounds ridiculous. Just as most traffic accidents happen
with 30 miles of home, most burglaries happen when you are away for
less than a day. The one time 25 years ago that this house was
burgled, I was only away for 2 hours, Sunday around 6, in the summer
when the sun was still out.

If that's not the case, then it sounds like a very inconvienient lock,
given that you have to go through some physical gyrations to remove
the inner key every time you leave.

Exactly. My system, and that of most people, is simple and easy. We
had another deadlock that we used when people were home but wanted to
lock the door. To get out, we unlatched that, went out and I guess we
locked that one if someone was still home. (although when I was awake,
I didn't care if the door was locked.) The last one, almost always me,
locked the double dead bolt.
