Pemko CHS83HD1 Half Surface Continuous Hinge 83 in Grade 1

Product Description

The PEMKO CHS83HD1 is a half surface continuous hinge rated Heavy Duty Grade 1, designed for high-cycle commercial door applications. At 83 inches in length, it spans nearly the full height of a standard commercial door, distributing load evenly along the entire door edge rather than concentrating stress at individual knuckle points. The satin aluminum clear anodized finish provides corrosion resistance suitable for interior and light commercial exterior environments. Licensed door hardware installers and commercial finish carpenters are the typical trades responsible for specification and installation.

This continuous hinge is suited for commercial and institutional settings where doors face heavy daily use, including schools, hospitals, government facilities, and high-traffic office buildings. The half surface mounting configuration means one leaf mounts to the face of the door while the other mounts to the face of the frame, reducing the need for deep mortising and simplifying retrofit installations on existing steel or wood door frames.

Key Features

• 83-inch length provides full-height load distribution along the door edge
• Heavy Duty Grade 1 rating for high-cycle, high-traffic commercial applications
• Half surface mount eliminates the need for full-length mortising on both door and frame
• Satin aluminum clear anodized finish resists corrosion and maintains appearance under frequent cleaning
• Continuous knuckle design reduces pivot stress compared to standard butt hinges

Compatibility

Designed as an OEM-style replacement or new-installation continuous hinge for commercial-grade steel and wood doors requiring an 83-inch half surface hinge with Grade 1 hardware specifications.

Installation Notes

Installation is typically performed by a licensed door hardware installer or commercial carpenter familiar with ANSI/BHMA hardware standards. Shut down any door closer or automatic operator before removing existing hardware. Pilot holes should be drilled to the fastener manufacturer's specification to avoid splitting wood stiles or stripping tapped holes in steel frames. Verify door and frame alignment before final fastener torque to ensure consistent hinge gap along the full 83-inch length.
