Glynn-Johnson 90 Series Heavy Duty Surface Overhead Door Holders and Stops
The Glynn-Johnson 90 Series Heavy Duty Surface Overhead Door Holders and Stops deliver exceptional versatility for commercial door control applications. Designed for use with most surface-applied door closers, these units feature a heavy-duty channel/slide-arm design with an offset jamb bracket that allows simple field modification of functions without replacing hardware. Provided templates support variable mounting positions ranging from 85° to 110° hold-open or stop angle, and the non-handed design simplifies installation across virtually all door types — including doors with conventional butt-type hinges or specialty hinges. Available in heavy-gauge brass, 300 Series stainless steel, and steel to suit a broad range of design and environmental requirements.

Glynn-Johnson 902H-SP28 – Frequently Asked Questions

These heavy duty holders work on commercial overhead doors up to 10 feet wide and 400 pounds. Compatible with sectional overhead doors, roll-up doors, and service doors in commercial and industrial applications.
2) How do I determine left hand vs right hand for installation?
Stand inside looking out at the door. Right hand units mount on the right side, left hand on the left. The arm extends toward the center of the door opening when installed.

Standard finish is aluminum. Optional finishes include dark bronze anodized and black powder coat for different architectural requirements and weather resistance.
4) What is the holding power of these heavy duty door holders?
90 Series holders provide 75 foot-pounds of holding torque. This heavy duty rating handles high wind loads and frequent use in commercial environments.
5) Do these door holders meet fire code requirements?
Check local fire codes for overhead door holder requirements. Many jurisdictions require electromagnetic or fusible link release systems for fire-rated openings rather than manual holders.

Common replacement parts include hold-open arms, mounting brackets, adjustment screws, and release handles. Contact us with your model number for specific part availability.
7) How do I install surface-mounted overhead door holders?
Mount the holder to the inside face of the door frame or wall using provided fasteners. Position the arm to contact the door when fully opened. Follow manufacturer template for exact placement and drilling.

These holders complement other Glynn Johnson overhead door hardware including closers, operators, and track systems for complete door control solutions.
10) Can these holders work in outdoor or weather-exposed locations?
Yes, with proper finish selection. Use anodized or powder coat finishes for exterior installations. Regular maintenance prevents binding from dirt and weather exposure.
11) What door measurements do I need before ordering?
