Glynn Johnson 454H32D Surface Overhead Door Holder Size 4

Product Description

The GLYNN JOHNSON 454H32D is a medium duty, hold-open surface overhead door holder designed for commercial and institutional door control applications. This size 4 unit mounts to the surface of the door and frame, using an overhead track-and-arm mechanism to hold the door in the open position. The satin stainless steel finish provides corrosion resistance suited to high-traffic environments. At 25.9 inches in length, it offers reach appropriate for wider door openings typical in commercial settings. Installation is handled by door hardware specialists, locksmiths, or general contractors working to specification.

The 454H32D is suited for interior commercial doors in offices, healthcare facilities, schools, and institutional buildings where a reliable hold-open function is required without the use of floor-mounted stops. The surface-mounted overhead design keeps the hardware clear of foot traffic and floor obstructions. Its medium duty rating makes it appropriate for standard commercial door weight and frequency-of-use conditions.

• Hold-open function keeps door stationary at desired open position

Installation Notes

Installation is typically performed by a licensed door hardware technician or qualified contractor. The door and frame must be properly aligned before mounting. Secure all fasteners to the door and frame per the manufacturer template to ensure correct arm travel and hold-open engagement. Verify local building and fire codes regarding hold-open devices, as fire-rated door assemblies may have restrictions on the use of non-fusible hold-open hardware.
