81 Series Heavy-Duty
Glynn-Johnson offers the most complete line of overhead holders and stops, providing solutions for the most complex door control problems. These surface-mounted holders and stops offer the most effective shock-absorbing capacity, helping protect doors, frames and 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.

Designed for heavy-duty applications, these models provide long-lasting protection for doors, frames, hardware and surrounding walls or obstructions. They are compatible with most door closers and feature an extremely reliable Hold-Open function and rugged shock absorption. All models feature jointed-arm design and centered jamb bracket.
Designed for heavy-duty applications, 81 series models are ideal for doors that are opened frequently. They provide long-lasting protection to doors, frames, hinges, related hardware and surrounding walls or obstructions.
81H Series Hold-Open
(Suffix 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 act as stops and shock absorbers. In the “on” position, they hold the door open at a preset position between 85º and 110º. The Hold-Open force is not adjustable in the 81H Series.
81S Series Stop-Only
(Suffix 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.
UL Classification
The 81 series Stop-Only models are classified by Underwriters Laboratories (UL) as Miscellaneous Fire Door Accessories. This classification applies to use on either Hollow Metal Fire Doors or Wood Fire Doors. These units may be used on doors of any rating. As a reminder, the Miscellaneous Fire Door Accessories (GVUX) section is defined by UL as: “Miscellaneous fire door accessories are intended in the individual Listings. The accessories have been investigated to determine that when installed in accordance with the manufacturer’s instructions, the accessories do not adversely affect the fire rating of the fire door and/or fire door frames.”
Dead-Stop Templating
If a wall or similar obstruction is in place at an opening angle of 110º or less (i.e. doors that open back-to-back), Dead Stop Templating should be used for all Hold-Open and Stop-Only models. The Dead Stop position is reached when the shockabsorbing spring is fully compressed. The initial degree of opening will be 5º to 7º less than the Dead Stop opening.
Example: If the holder is templated to 100º Dead Stop, the door will hold open somewhere between 93º to 95º, but no further than 100º.
Environmental Considerations
Environmental factors should always be considered when specifying overhead holders and stops. Doors that are positioned on a building’s exterior or subject to corrosive conditions should be equipped with a holder constructed primarily of stainless steel or brass materials. For interior applications, steel is acceptable, though brass substrates generally provide a more attractive architectural-grade finish.

Suffix J (Angle Jamb Bracket):
An option on the 81 series is the “J” angle jamb bracket, which converts the standard model to hinge side mounting (on Stop-Only models) or to flush transom mounting. The angle jamb bracket affixes to the standard jamb bracket. If ordered with unit add suffix J. If need separately order 81J by finish needed.
Suffix SOC (Pin-in-Socket Security Screws):
A screw package with pin-in-socket screws for mounting the door bracket and the jamb bracket is provided instead of the standard screw package.
Suffix SHIM (Blade Stop Shims):
Shim kits are available in 3 sizes
81 SHIM1 is a 1/4" Shim Kit
81 SHIM2 is a 1/2" Shim Kit
81 SHIM3 is a 3/4" Shim Kit
If ordered with overhead, add suffix SHIM (1, 2 or 3). If needed separately order 81 SHIM 1, 2, or 3 by finish needed.
