it's not clear to me what application you are thinking about.

if you are looking at strengthening your home entry door against intrusion - these heavy duty box strikes can be installed without needing a lot of skill.

they also have other door security hardware. i've seen their products at do it best and other home improvement stores.

a longer throw deadbolt, when coupled with one of these, looks like 'regular' door hardware. but you'd probably put a hole in the door - or tear the door off the hinges - before attaining entry.

it buys you time to 911 and / or unlock the weapons.
