Hager Hinge RC18423121DEA58 Full Mortise Hinge Dull Black

Product Description

The HAGER HINGE RC18423121DEA58 is a full mortise, plain bearing door hinge designed for residential interior and exterior door applications. Measuring 3.5 inches by 3.5 inches with a 5/8-inch radius corner profile, this hinge installs flush into mortised door edges and jambs for a clean, finished appearance. The dull black finish provides a low-sheen aesthetic suited for contemporary or traditional door hardware sets. Weighing 0.4 pounds per unit, it ships and is sold individually. Plain bearing construction makes this hinge appropriate for standard-frequency residential doors rather than high-cycle commercial applications.

This hinge is intended for residential full mortise door installations where a standard 3.5 x 3.5 inch hinge footprint is specified. It is commonly used on interior passage doors, bedroom doors, and closet doors. The 5/8-inch radius corner geometry is a widely adopted residential profile and is compatible with standard mortise routing templates used by door and frame manufacturers. Finish carpenters, door hardware installers, and general contractors typically specify and install this style of hinge during new construction or renovation work.

Compatibility

Designed as an OEM-style replacement or new-installation hinge for standard residential full mortise door applications requiring a 3.5 x 3.5 inch, 5/8-inch radius plain bearing hinge in a dull black finish.

Installation Notes

Installation is typically performed by finish carpenters or door hardware technicians using a chisel or router with a mortise template to prepare the door edge and jamb. Ensure the mortise depth matches the hinge leaf thickness to achieve a flush fit. Screws should be driven straight and flush to avoid binding. Follow local building codes for door hardware requirements on rated or fire-assembly doors.
