DHHD224 | Full Mortise
• DHHD224 is an Aluminum Continuous Geared Concealed Leaf Hinges. This model provides a 3/32″ door inset.
• The DHHD224 can be used with any standard frame without hinge preps, and either with or without reinforcements depending on door weight. Clearance required between the hinge edge of the door and the frame rabbet is 5/16″ (7.9mm) minimum.”HD” models have additional bearings for heavy-duty application.
• All Hinges are supplied approximately 1″ to 1-5/16″ shorter than the nominal door height to avoid threshold or carpet clearance problems. If the hinge must be trimmed shorter, first determine the correct hand of the door and orientation of the hinge. Then mark and trim from the bottom of the hinge only – do not cut from the top end.
