Full Mortise Equal-Leaf Design

• Equal-leaf geometry

• No inset

• Full-mortise installation

• Continuous heavy-duty door support

Always verify the existing door and frame preparation before ordering.

Continuous Geared Hinge Construction

Conventional butt hinges support a door at only several individual points.

A continuous geared hinge supports the door along nearly its entire height, helping:

• Distribute door weight

• Reduce localized frame stress

• Minimize sagging

• Maintain latch alignment

• Reduce wear at individual hinge locations

• Maintain consistent door clearances

• Improve performance on frequently used doors

Heavy-Duty Performance

The HDGH-112 is rated for compatible doors weighing up to:

450 lb

This makes it well suited for demanding commercial openings where conventional hinges may experience accelerated wear from heavy doors and frequent operation.
