Hager Hinge 127941210D Full Mortise Plain Bearing Hinge

Product Description

The HAGER HINGE 127941210D is a full mortise, five knuckle, plain bearing hinge finished in black nickel. Standard weight construction makes it suited for interior and light-duty commercial door applications where a clean, durable hinge is required. The leaf dimensions are 4.5 inches by 4.5 inches, providing a balanced swing profile for standard door widths. The plain bearing design requires no lubrication under normal service conditions, reducing maintenance demands. Installation is performed by carpenters, finish contractors, and door hardware specialists working on new construction or retrofit projects.

This hinge is appropriate for full mortise installation on residential and light commercial doors. The five knuckle configuration provides clean barrel alignment and smooth pivoting action. The black nickel finish suits modern and transitional door designs where consistent hardware finish coordination is required. This unit is sold individually and is non-returnable.

Installation Notes

Installation is typically performed by a finish carpenter or door hardware technician. Mortise the door edge and frame jamb to the exact leaf dimensions before mounting to ensure flush seating. Use a chisel and router or dedicated mortise jig to achieve a clean pocket. Confirm door weight and frequency rating before selecting hinge quantity per door leaf.
