Prime-line U 9537 Lock and Door Reinforcer Solid Brass

Product Description

The PRIME-LINE U 9537 is a solid brass lock and door reinforcer designed to strengthen the most vulnerable area of an entry door - the latch and lock zone. The plate is non-recessed and pre-punched for mounting, making field installation straightforward. It fits doors that are 1-3/4 inches thick and features two 2-1/8 inch bores set 5-1/2 inches on center with a 2-3/8 inch backset. The plate measures 3-7/8 inches wide by 10-7/8 inches tall and weighs 0.95 pounds. All mounting fasteners are included. Licensed locksmiths, carpenters, and general contractors typically handle this type of door hardware installation.

This reinforcer is suited for residential entry doors constructed of wood or metal. It accommodates mortise latches, drive-in latches, key-in knob locksets, deadbolts, and combination locksets. Common applications include reinforcing doors that have experienced forced-entry damage or upgrading existing door frames to meet higher security standards. The brass finish integrates cleanly with standard residential door hardware.

Installation Notes

Installation should be performed by a licensed locksmith, finish carpenter, or qualified contractor familiar with door hardware. Before beginning, ensure the door is in a stable, closed position and that all existing lock hardware is removed or disengaged as needed. Confirm door thickness, bore size, backset, and hole center measurements match the reinforcer specifications prior to fastening. Follow applicable local building codes for residential door security hardware.
