National Mfg N241-208 4x4 Black Square Corner Door Hinge

Product Description

The NATIONAL MFG/SPECTRUM BRANDS HHI N241-208 is a 4-inch by 4-inch full mortise door hinge finished in black with square corners. Built from heavy gauge steel, it is designed for residential interior and exterior door applications where a clean, durable pivot point is required. The removable pin simplifies door installation and removal without disturbing the leaves already mortised into the frame and door edge. A nib on the hinge body delivers a finished appearance once the door is hung. Carpenters, finish contractors, and general contractors are the typical installers for this hardware.

This hinge fits standard residential interior and exterior door applications. The full mortise design requires routed recesses in both the door edge and the door frame jamb so the hinge sits flush with the wood surface. The square corner profile is suited to doors with square-routed mortise pockets. Sold individually, one hinge per pack, making it straightforward to order the exact quantity needed for a job. Package quantity is 5 packs per unit of measure.

Installation Notes

Installation is performed by carpenters or general contractors using a chisel and router to cut flush mortise pockets in the door edge and jamb before seating the hinge leaves. Power down any electric strike or access control hardware on the door circuit before beginning work. Verify hinge placement against local building codes and door manufacturer specifications for spacing and quantity of hinges required per door. The removable pin should be tapped out with a non-marring punch and hammer when lifting the door free of the frame.
