Upgrade your door security with this antique brass lock and door reinforcer, designed to help prevent forced entry by strengthening the vulnerable area around your lock. Perfect for repairing or reinforcing both metal and wood doors, this plate fits 1-3/4-inch thick doors with mortise or drive-in latches. Crafted from durable solid brass or stainless steel with an elegant antique brass finish, it features two 2-1/8-inch bores spaced 3-5/8 inches apart and offers backset options of 2-3/8 inches or 2-3/4 inches. The non-recessed plate comes pre-punched for easy installation, and all necessary mounting hardware is included. Please review the line art drawing for exact measurements before purchasing, as this item is not universal.
