DHHD157 is an Aluminum Continuous Geared Full Surface Hinge that provides a 1/16″ door inset. It can be used with any standard frame without hinge preps, and either with or without reinforcements depending on door weight. The frame face must have a flat surface at least 7/8″ wide. Clearance between the hinge edge of the door and the frame rabbet may be from 1/32″ to 1″ (0.8 – 25.4mm). “HD” models have additional bearings and frame fasteners for heavy-duty application.
