Pemko CFM83HD1-M Full Mortise Heavy Duty Modular Hinge

Product Description

The PEMKO CFM83HD1-M is a Grade 1 full mortise heavy duty modular continuous hinge finished in satin aluminum clear anodized. Rated at the highest commercial grade, this hinge is built for high-traffic door openings that demand long service life and consistent performance. At 83 inches in length, it spans nearly the full height of a standard commercial door, distributing load across the entire door edge rather than concentrating stress at two or three pivot points. Installers in commercial construction and door hardware trades specify this type of continuous hinge where conventional butt hinges are insufficient for the application.

The CFM83HD1-M is suited for commercial and institutional door openings including schools, hospitals, government buildings, and high-traffic corridors. Full mortise installation means both the door and the frame are routed to accept the hinge leaves flush, producing a clean finished appearance and a secure mechanical connection. The modular design allows field cutting to exact door height when required. This hinge is typically installed by commercial door and hardware specialists or finish carpenters working to specification on hollow metal or wood door assemblies.

Key Features

Compatibility

Installation Notes

Installation is typically performed by a licensed commercial door and hardware technician or finish carpenter. Both the door edge and frame must be mortised to the correct depth before mounting to ensure the hinge sits fully flush. Follow the door manufacturer specifications and applicable building codes for fastener pattern and door preparation. Verify door weight and frequency ratings against hinge capacity before installation.
