Works Great
We painted ours to match our door knob and it was perfect. Just make sure your measurements are right. Good product and we received it quickly!

Smart product
Solved my problem. Previously, someone butchered the door to the point I couldn't put a deadbolt on. This works perfect and is very strong. Looks good too.

Flimsy, but did itโs job.
This reinforcer did itโs intended job, but is a bit too thin. It caved a bit when I reinstalled my lock.

Easy install
Following a break in, this was part of our โbeefing up security missionโ. This will help prevent our steel door from splitting if another attempt is made. It came with all screws needed and two nuts (no idea what they were for). No install instructions but I removed the deadbolt mechanism (not the bolt bit) and secured this to the edge of the door by the bolt, first. Then I replaced the mechanism and tightened all. Then I used the four screws to secure the plate front and back. The screws went into the steel with minimal effort, but you will need a power driver. I donโt think this could be done with a hand driver. Very happy with the quality.

Repaired my split door.
Door was split at latch and latch was loose. This bracket reinforced the split and secured the latch again.
