Glynn-Johnson 81 Series Heavy Duty Surface Overhead Door Holders and Stops

The Glynn-Johnson 81 Series are surface-mounted overhead door holders and stops engineered to deliver rugged, heavy-duty door control for commercial applications. Featuring a jointed-arm design that provides the most effective stop mechanism available, the 81 Series offers superior shock-absorbing capacity to protect doors, frames, and hardware from impact damage. Available in two models — the 81H Series hold-open model and the 81S Series stop-only model — and offered in heavy gauge brass, 300 Series stainless steel, and steel, the 81 Series provides the broadest range of finishes in the industry while maintaining compatibility with most door closers.

Key Features

  • Jointed-Arm Stop Mechanism: The jointed-arm design provides the most effective stop mechanism available, delivering superior shock-absorbing capacity to protect doors, frames, and all associated hardware.
  • Surface-Mounted Installation: The shock absorber bracket is surface mounted — typically with sex bolts — and the jamb bracket mounts to the stop of the frame, requiring a minimum of door and frame preparation.
  • Non-Handed Design: Simplifies installation and stocking by eliminating the need to specify handing, reducing inventory complexity for commercial projects.
  • Two Available Models: The 81H Series provides a reliable hold-open function, while the 81S Series delivers heavy-duty stop-only performance — both available in four standardized sizes to fit different door applications.
  • Broad Material Selection: Available in heavy gauge brass, 300 Series stainless steel, and steel, offering the broadest range of finishes in the industry to suit diverse architectural requirements.
  • Corrosion Resistance: Brass and 300 Series stainless steel construction offer the highest resistance to corrosion for longer-lasting performance across a variety of weather conditions; other base materials are suitable for normal interior use.
  • Door Closer Compatibility: Improved compatibility with door closers for better door control and reduced wear and tear on all door hardware components.
  • Flexible Options: Available options include the angle jamb bracket (J), blade stop shims (SHIM), and pin-in-socket security screw package (SOC) for extended configuration flexibility.

Glynn-Johnson 813H-652 – Frequently Asked Questions

1) How do I pick the right size Glynn-Johnson 81 Series overhead stop for my door width?
Size is chosen off the door opening width and the hanging method, and the 81 Series covers four sizes: 27-1/16 to 33 inches on butt or offset pivots (33-1/16 to 39 inches center hung), 33-1/16 to 39 inches (39-1/16 to 45 center hung), 39-1/16 to 45 inches (45-1/16 to 51 center hung), and 45-1/16 to 54 inches (51-1/16 to 59 center hung). Measure the actual door width, then check which bracket the door hangs on, because a center hung door takes the next size band down from what its width alone would suggest.
2) What is the difference between the Glynn-Johnson 81H and 81S?
Function is the only thing that separates them. The 81H holds the door open at the stop point; the 81S stops the door and lets it swing back closed. If the opening is on a closer and you want the door parked open for deliveries, carts, or ventilation, order the H. If you only need to protect the wall and the door edge and the door must always close, the S is the one to spec. Both are the same heavy duty jointed-arm assembly otherwise.
3) Will an 81 Series surface overhead stop work on a door that already has a closer?
Yes. The 81 Series is built for compatibility with most door closers, and the jointed arm absorbs the shock at the stop point rather than passing it into the closer arm and frame. That is the usual reason to add one to a closer opening: the closer controls the swing, the overhead stop controls where the swing ends.
4) What prep does the door and frame need for a surface mounted 81 Series holder?
Minimal. The shock absorber bracket mounts on the face of the door, typically with sex bolts, and the jamb bracket mounts to the stop of the frame. Nothing gets mortised into the door edge or the frame head, which is what makes this the practical retrofit when the opening was never prepped for a concealed stop. Glynn-Johnson publishes installation instructions for the 81 Series surface overhead holder if you want the template before you drill.
5) My frame has an angled or narrow stop, will the standard 81 Series jamb bracket mount?
There are two order options for exactly that. The J option substitutes an angle jamb bracket, and Glynn-Johnson publishes separate installation instructions for the angle bracket version. Where the blade stop is too shallow to land the bracket flat, the SHIM kits fill it out: SHIM-1 for 1-1/4 inch, SHIM-2 for 1-1/2 inch, and SHIM-3 for 1-3/4 inch. Measure the stop before ordering, since picking the shim on site is not an option once the bracket is up.
6) Should I use a surface overhead stop or a concealed one?
A surface stop like the 81 Series mounts on the face of the door and the frame stop, so it goes onto an existing opening with almost no prep and it can be serviced without pulling the door. A concealed unit hides in the top rail and the frame head, which looks cleaner but requires the door and frame to be prepped for it, so it is really a new-door or new-frame decision. ZenSupply carries concealed alternatives including the ABH 1000 Series and the Sargent 690 heavy duty overhead concealed stop and holder if the appearance matters more than the retrofit.
7) What should I use instead of a Glynn-Johnson 81 overhead stop if the door has no room for surface-mounted hardware on the face?
Go to a concealed mount unit. The Sargent 690 is a heavy duty overhead concealed stop and holder with ANSI Grade 1 compliance, and the Norton Rixson 1 Series Checkmate is a heavy duty Grade 1 concealed stop and holder with a 110 degree opening. The ABH 1000 Series is a heavy duty concealed mount overhead stop carrying a fire rating. The 81 Series is the surface-mounted route, with the shock absorber bracket mounted to the door face and the jamb bracket to the stop of the frame, so it needs that face real estate the concealed units do not.
8) I need to limit how far the door swings and change that angle in the field. Does the Glynn-Johnson 81 do that?
The 81 Series is ordered to a fixed door opening range - four sizes covering 27-1/16 to 33 inches, 33 1/16 to 39 inches, 39 1/16 to 45 inches, and 45 1/16 to 54 inches on butt or offset pivots - and the function is chosen at order as 81H hold-open or 81S stop-only. If the stop angle has to be set or reset on site, the ABH 1000A Series is a heavy duty concealed mount stop and holder with field-adjustable opening control, and the 1000RA and 1000SA Series are heavy duty concealed stop and holders with adjustable opening control. The Norton Rixson 10-336 also offers adjustable opening control, and the 10-236 Checkmate is a surface stop and holder with an adjustable hold-open feature.
9) My spec calls for a fire rated overhead stop. Can I substitute the Glynn-Johnson 81 Series?
Do not treat them as interchangeable on that line of the spec. The ABH 1000 Series is the heavy duty concealed mount overhead door stop in the set that carries a fire rating in its identity. The 81 Series is a heavy duty surface-mounted holder and stop with a jointed-arm mechanism and hold-open or stop-only function, so if the drawing calls out a fire rated unit, specify the ABH 1000 Series against that opening.
10) My spec sheet requires an ANSI Grade 1 overhead stop and holder. Which options meet that?
Three peers carry Grade 1 in their catalog data: the Sargent 690, a heavy duty overhead concealed stop and holder; the Norton Rixson 1 Series Checkmate, a heavy duty concealed stop and holder with a 110 degree opening; and the Sargent 1530, a concealed mount stop and holder with a 110 degree opening rated medium duty. The Norton Rixson 10-336 is Grade 1 at standard duty with adjustable opening control. For a project where the Grade 1 callout drives the submittal, those are the units to put on the schedule.
11) Do I have to specify handing when ordering a Glynn-Johnson 81 Series overhead stop?
No. The 81 Series is non-handed, so one part covers left and right hand openings. For a property manager or a facility stockroom, that means one shelf item per size and finish instead of two, and no risk of a hand callout error on the order.
12) Is there a tamper resistant fastener option for an 81 Series overhead stop in a school or detention area?
Order the SOC option and the stop ships with a pin-in-socket security screw package. That is the configuration to use on openings where the hardware is reachable and gets picked at: student corridors, restrooms, holding areas, public housing common doors. Standard fasteners come on the None option.
13) What finishes does the Glynn-Johnson 81 Series come in so I can match the rest of my door hardware?
Seven finishes: 652 chrome-like coating, US3 polished brass, US4 satin brass, US10 satin bronze, US10B oil rubbed bronze, US32 polished stainless, and US32D satin stainless. US32D is what most commercial openings already run, and US10B is the usual match on a hospitality or dark-bronze package. Note the finish also implies the base material, so a US32D stop is stainless and a US4 stop is brass.
14) Will an overhead stop keep my doors from getting wrecked by wind or carts slamming them open?
That is what the 81 Series is built to do. The jointed-arm mechanism absorbs the shock at the end of the swing instead of transmitting it into the door, the frame, and the closer, which is where the damage normally shows up first: cracked top rails, pulled closer arms, split jambs. On high-traffic openings in schools, hospitals, warehouses and multi-tenant buildings, adding an overhead stop is usually cheaper than repeating the door repair.
15) What do I need to order besides the stop itself to finish the installation?
For a standard frame, nothing extra: the shock absorber bracket and the jamb bracket both come with the unit and mount with fasteners, typically sex bolts through the door. The add-ons are situational and are ordered as the device option on the same part: the J angle jamb bracket for frames the standard bracket will not sit on, a SHIM kit (1-1/4, 1-1/2 or 1-3/4 inch) to build out a shallow blade stop, or SOC pin-in-socket security screws. Pick one of those at order time rather than adding it later, since it changes the part you receive.
16) Is there a lighter duty overhead stop for an interior door that does not need the 81 Series?
For a low-traffic interior opening, the Don-Jo 3023 and 3024 are standard duty concealed overhead door stops in satin stainless steel, the 3023 sized for 30 inch doors and the 3024 for 36 inch doors. The DORMA 711F is a standard duty concealed friction stop covering a 21 to 27 inch door opening. The Norton Rixson 10-336 is a standard duty overhead stop with adjustable opening control. All of these sit below the 81 Series, which is built as heavy duty commercial door control with a jointed-arm shock-absorbing stop.
17) What is the difference between the Glynn-Johnson 81 Series and the DORMA 900 Series for a heavy duty opening?
Both are heavy duty stop and holder lines. The DORMA 900 Series is catalogued as heavy duty stops and holders. The 81 Series separates the two functions at the model level, 81H for hold-open and 81S for stop-only, is non-handed so handing does not have to be specified, and is ordered by door opening range across four sizes from 27-1/16 inches up to 54 inches on butt or offset pivots. The 81 Series also takes the J angle jamb bracket, SHIM-1, SHIM-2 and SHIM-3 blade stop shim kits, and the SOC pin-in-socket security screw package as ordering options.
18) I am replacing an old overhead stop and want to avoid new door prep. What are my choices?
The 81 Series is surface mounted - the shock absorber bracket goes on with sex bolts and the jamb bracket to the stop of the frame, requiring a minimum of door and frame preparation - and it is non-handed, so the same part works on either hand. The Norton Rixson 10-236 Checkmate is the other surface-mounted stop and holder in the set, with an adjustable hold-open feature. If the door already has a concealed mortise pocket from the old unit, a concealed line such as the Sargent 690 or the Norton Rixson 1 Series Checkmate reuses that prep instead.
19) Is the Sargent 1530 the same thing as a Glynn-Johnson 81 stop and holder?
No. The Sargent 1530 is a concealed mount door stop and holder with a 110 degree opening, rated medium duty and ANSI Grade 1. The 81 Series is surface mounted with a jointed-arm stop mechanism, rated heavy duty, and ordered as either the 81H hold-open or the 81S stop-only model in four door opening sizes. Mount type and duty level both differ, so the 1530 is not a drop-in for an opening specified around the 81.
