Help strengthen entry doors against forced-entry attempts with the Prime-Line MP9453 Lock and Door Reinforcer. Designed to reinforce one of the most vulnerable areas of a door, this security plate helps repair damaged lock areas and add protection to both wood and metal entry doors. Ideal for residential security upgrades, rental property maintenance, and door repair projects, it provides a cost-effective solution for reinforcing weakened door surfaces without replacing the entire door.
Constructed from durable stainless steel with a natural finish, this non-recessed reinforcement plate is engineered for long-lasting strength and corrosion resistance. By covering and reinforcing the lock area, it helps distribute impact forces over a larger section of the door, reducing stress around the lock bore and helping deter forced-entry attempts. The pre-punched design simplifies installation and allows for secure attachment using the included fasteners.
Designed for 1-3/4 in. thick doors equipped with mortise or drive-in latch systems, this reinforcement plate accommodates standard key-in-knob locksets with a 2-1/8 in. bore and 2-3/4 in. backset. Measuring 4-15/16 in. wide by 9 in. tall, it provides expanded coverage for added door protection and repair capability. Compare dimensions with your existing door preparation before purchasing to ensure compatibility.
