About This Project

Install a door reinforcer on your entry and garage service doors to help discourage break-ins. Reinforcers are three-sided metal plates that encase and strengthen the door around the latch, which is a door’s most vulnerable area. The $11 reinforcer shown is meant to strengthen door latches, but you can also buy reinforcers that strengthen deadbolts (about $7). Install them on fiberglass, wood or steel doors. A reinforcer extends the door edge about 1/32 in., and so may rub the door frame of tightfitting doors. If so, slightly deepen the hinge mortises with a chisel to widen the gap at the latch side. Or chisel a 1/32-in. recess into the door edge so the reinforcer fits flush.

Door reinforcers are found at home centers and well-stocked hardware stores. For more information, contact Mag Security, (714) 891-5100 or www.magsecurity.com.
