Prime-Line Lock and Door Reinforcer, 2-1/8 x 2-3/8 x 1-3/8in., Stainless Steel, MP10852

Help strengthen vulnerable entry door lock areas and improve resistance against forced entry with the Prime-Line MP10852 Lock and Door Reinforcer. Designed for 1-3/8 in. thick doors, this reinforcement plate helps protect one of the most commonly targeted areas of a door by reinforcing the lock bore and surrounding surface. Ideal for both security upgrades and repair applications, it can be used on wood and metal doors to help restore structural integrity and extend door life. Constructed from durable stainless steel, this reinforcer is built to withstand everyday use while providing long-lasting corrosion resistance. The reinforcement plate fits doors with a 2-1/8 in. lock bore and a 2-3/8 in. backset, making it suitable for many standard key-in-knob lock installations. By distributing force over a larger area of the door, it helps reduce stress around the lock opening and strengthens damaged or weakened door surfaces. Measuring 3-7/8 in. wide by 4-1/2 in. high, this security reinforcement plate installs easily using the included mounting hardware. Whether repairing a damaged entry door or adding preventative security protection, this reinforcer offers a practical and economical solution. Compare door dimensions and lock preparation measurements before purchasing to ensure compatibility.
