National Marker N195677 4 in Square Broad Door Hinge

Product Description

The NATIONAL MARKER N195677 is a 4-inch square broad door hinge built from zinc-plated steel with a brass loose pin. It is part of the National catalog V504 through V504BC series. The hinge is swaged for mortise-style installations, making it suitable for general utility and light industrial door applications. The loose, removable pin allows a door to be lifted free of its frame without removing the hinge leaves from the door or jamb. Licensed tradespeople and general contractors install this hardware during door hanging or service work.

This hinge is intended for general utility and industrial environments where a reliable, mortise-style pivot point is needed. The swaged construction ensures the leaves sit flush in a mortised recess. The removable pin design simplifies door removal for maintenance, painting, or replacement without disturbing the mounted hardware. It is sold individually.
