81 Series Surface Overhead Door Holder and Stop by Glynn-Johnson Hardware
Glynn-Johnson 81 Series Holders and Stops provide rugged, heavy-duty door control. The jointed-arm design provides the most effective stop mechanism available. The shock absorber bracket is surface mounted, usually with sex bolts. The jamb bracket is mounted to the stop of the frame, so a minimum of door and frame preparation is required.
Hold-Open (H) - The Hold-Open model should be used when doors will need to be held open at a preset position for an extended period. This allows unobstructed traffic flow. Hold-Open model provides a selective Hold-Open function. A simple turn of the thumbturn disables the Hold-Open function, allowing the unit to serve as a shock absorbing stop.
The Hold-Open mechanism is selective and may be turned on or off with a simple turn of the thumbturn. In the "off" position, these models acts as stops and shock absorbers. In the "on" position, they hold the door open at a preset position between 85° and 110°. The Hold-Open force is not adjustable in the 81H series.
Stop-Only (S) - When the Hold-Open function is not required, the Stop-Only models provide the same effective door control, without the Hold-Open feature. The Stop-Only model may be used on fire doors.
