Pemko DFM83HD1-M Full Mortise Heavy Duty Modular Hinge

Product Description

The PEMKO DFM83HD1-M is a Grade 1 full mortise heavy duty modular continuous hinge finished in dark bronze anodized aluminum. At 83 inches in length, it spans nearly the full height of a standard commercial door, distributing load evenly along the entire hinge edge. The anodized aluminum construction resists corrosion while keeping overall weight low. This hinge is installed by commercial door hardware specialists, locksmiths, and general contractors working on high-traffic commercial or institutional openings.

This hinge is suited for commercial and institutional applications where a full-height continuous hinge is required to handle frequent, heavy use. The full mortise design seats flush into the door and frame edge, maintaining a clean profile on the face of the opening. It is a practical choice for corridors, restrooms, utility rooms, and other high-cycle doorways where a traditional butt hinge would not provide adequate load distribution or longevity.

Installation Notes

Installation is typically performed by a licensed door hardware installer or commercial carpenter familiar with continuous hinge mortising. The door and frame must be properly mortised to the hinge manufacturer's specified depth before mounting. Ensure the door is fully supported and the opening is plumb and square prior to fastening. Always follow applicable building codes and hardware manufacturer guidelines for commercial door hardware installation.
