This 4" x 4" black door hinge is designed for doors and frames that require 5/8" radius round corners. The larger 5/8" radius corner style is common on many residential door hinge mortises and helps provide a clean replacement fit when matching an existing rounded hinge cutout. The black finish provides a clean, modern look that pairs well with black door knobs, levers, deadbolts, handlesets, cabinet hardware, and other matching home hardware. This hinge is commonly used on exterior doors, garage entry doors, heavier interior doors, and other applications where a 4" hinge is preferred. The full mortise butt hinge design allows the hinge to sit flush between the door and frame for a clean, finished installation. Matching 1" screws are included for straightforward installation.
