Rated 4.5 out of 5 by 2 reviewers.
Rated 5.0 out of 5.0 by Must-have for every door Easy to install. Just take the lock off the door and slip it on. It adds a lot of protection in a door's weak spot. Another good idea is a commercial-grade dead bolt, a thicker strike plate, and a metal lining that goes into the door jam for the dead bolt. August 6, 2013
