This may be a good idea for the gun or loading room. Has anyone installed one of these?

Nope, but I found this on CraigsList for $400.

Its made to replace a standard 36" door, but im building a cement-walled room in the basement for it. Complete with a big dehumidifier....

Steel door jams with a steel door work well too, and are easier to find, but more trouble to install. I suspect the door jam spreader that some police agencies use will still work, but they arn't as effective on steel door jams. Having been in the alarm business for 31 years gives you a good idea of what works and what doesn't work. I'm more concerned with the police coming into my home than I am a burglar.
