Deltana S44R51B Radius Corner Hinge Flat Black

Product Description

The DELTANA S44R51B is a 4-inch x 4-inch radius corner door hinge with a flat black finish, designed for architectural and door hardware applications. The hinge features a 5/8-inch radius corner profile and is sold as a pair, making it suitable for standard residential and light commercial door installations.

Installation Notes

Installation is typically performed by a finish carpenter or licensed contractor using a hinge mortise chisel or router jig. Ensure the door and frame are properly supported before removing existing hardware. Follow local building codes for hinge quantity and placement based on door height and weight. Do not overtorque screws, as doing so can strip the mortise and affect hinge alignment.
