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
1) How do I pick the right size Glynn-Johnson 90 Series overhead stop for my door?
Two things decide it: door width and how the door is hung. On butt hinges or offset pivots, the 902 covers 23 1/16 to 27 inches, the 903 covers 27 1/16 to 33, the 904 covers 33 1/16 to 39, the 905 covers 39 1/16 to 45, and the 906 covers 45 1/16 to 54. Center hung doors read a different column and every model steps up: 902 is 27 1/16 to 33 inches, 903 is 33 1/16 to 39, 904 is 39 1/16 to 45, 905 is 45 1/16 to 51, and 906 is 51 1/16 to 59. Measure the door width, then pick the model whose range for your hinge type brackets it. Between the five sizes the family runs from 23 1/16 inches up to 59 inches.
2) What is the difference between the H, S, SE and F functions on a Glynn-Johnson 90 Series overhead holder?
H is hold-open: the door catches at the set angle and stays there until you push it past. S is stop-only: it stops the door at the angle and lets it close normally, which is what you want on any opening that has to self-close every time. SE is a special stop-only built for particular door and closer combinations. F is friction hold-open, which holds by friction so the door can be repositioned by hand and left anywhere without fully closing. All four share the same channel and slide arm chassis, so the choice is about how the door needs to behave, not about a different unit.
3) Will a Glynn-Johnson 90 Series overhead stop work on a center hung pivot door or a door with specialty hinges?
Yes to both. The 90 Series is templated for conventional butt hinges and for specialty hinges and pivots, and the sizing chart carries its own center hung column: a 906, for instance, covers 51 1/16 to 59 inches center hung against 45 1/16 to 54 inches on butt hinges or offset pivots. Read the column that matches how the door is hung, not just the width, or you will land on the wrong model. The unit is non-handed, so the same part works on a left hand or right hand door.
4) The opening cannot take a surface mounted overhead stop - what overhead holder works instead of the Glynn-Johnson 90 Series?
Go to a concealed unit. The ABH 4000 Series is a concealed mount overhead stop and holder with medium duty construction, and the ABH 4000RA Series is a concealed mount medium duty overhead door holder and stop with adjustable opening control. Both mount into the top of the door and the frame soffit instead of onto the face of the door, so nothing is exposed on the push side. The Glynn-Johnson 90 Series is a surface mount overhead stop and holder in heavy duty construction, mounting the channel arm on the door face with a jamb bracket at the frame - the right choice where the door and frame can be drilled for a face-applied unit, but not where a concealed pocket is required.
5) What other heavy duty surface mounted overhead stops and holders compare to the Glynn-Johnson 90 Series?
The closest peers are the Norton Rixson 9ADJ Checkmate heavy duty adjustable surface mount door stop and holder with 110 degree opening, the Norton Rixson 10 Series Checkmate surface door stop/holder with slide track arm, and the Sargent 590 heavy duty overhead surface mount door stop/holder with bronze construction. All three are Grade 1 heavy duty units, and the Norton Rixson 10 Series uses a slide track arm like the Glynn-Johnson channel/slide-arm design. What separates the Glynn-Johnson 90 Series is its span: five models covering 23 1/16" to 59" of door width, a non-handed body, and four functions - H hold-open, S stop-only, SE special stop-only, and F friction hold-open - with the function field-modifiable through the offset jamb bracket rather than fixed at order.
6) I need the stop angle adjustable after the unit is mounted - what overhead stop does that instead of the Glynn-Johnson 90 Series?
The ABH 3300A Series is a surface mount overhead stop and holder with adjustable opening control, and the Norton Rixson 9ADJ Checkmate is a heavy duty adjustable surface mount door stop and holder with a 110 degree opening; the ABH 4000RA Series offers adjustable opening control in a concealed mount medium duty body. On the Glynn-Johnson 90 Series the stop or hold-open angle is set between 85 and 110 degrees by the mounting position chosen from the provided templates, so the angle is decided when the jamb bracket is drilled. What the 90 Series does change after installation is the function - the channel/slide-arm and offset jamb bracket design lets H, S, SE, and F be converted in the field without replacing the unit.
7) Do I need to specify handing when I order a Glynn-Johnson 90 Series door holder?
No. The 90 Series is non-handed, so one unit fits a left hand or right hand door and you never have to call the hand at order time. What you do specify is size (902 through 906, chosen off the door width and hinge type), function (H hold-open, S stop-only, SE special stop-only, or F friction hold-open), and finish. For a property manager or facility buyer that non-handed build is the useful part: you can stock a couple of sizes on the shelf and cover openings that swing either way.
8) Can a Glynn-Johnson 90 Series stop-only be changed to a hold-open later without replacing it?
Yes. The channel and slide arm assembly with its offset jamb bracket is built so the function can be modified in the field, without swapping out the hardware. A stop-only can be converted when a room changes use and a door needs to be held open, or the reverse. For anyone standardizing a building, that changes the stocking math: you carry one size and finish and set function at the door instead of holding four separate part numbers.
9) Which Glynn-Johnson 90 Series material holds up on an exterior or coastal door?
Brass or 300 Series stainless steel. The 90 Series is built in heavy-gauge brass, 300 Series stainless, and steel, and it is the brass and stainless versions that carry the highest corrosion resistance of the three for weather-exposed and washdown openings. Steel is the choice for dry interior work. On an exterior opening the stainless finishes, US32 polished stainless and US32D satin stainless, keep the substrate visible rather than relying on a coating to do the protecting.
10) Do I still need a floor stop or wall bumper if I install a Glynn-Johnson 90 Series overhead stop?
No. An overhead stop takes the door's travel at the head of the frame, so it does the job of a floor or wall stop with nothing projecting off the floor or the wall. That is why they get specified in hospital corridors, schools and lobbies where a floor stop is a trip hazard or the surface behind the door is glass, millwork or a monitor. Set the 90 Series anywhere from 85 to 110 degrees when you lay out the template so the leaf comes to rest clear of whatever is behind it.
11) I only need a stop on a 26 inch interior office door. Is the Glynn-Johnson 90 Series more than I need?
It may be. The 902 does cover 23 1/16 to 27 inches on butt hinges or offset pivots, but the 90 Series is a heavy duty commercial unit built for abuse. On a low-traffic interior door where you do not need heavy duty construction or field-convertible functions, ZenSupply also carries the DORMA 701F, a standard duty surface applied friction stop for 21 to 27 inch door openings, and the Sargent 1540, a medium duty Grade 1 surface mount stop/holder with a 110 degree opening. If that door gets propped daily or takes cart traffic, stay with the 90 Series.
12) My frames are flush, not rabbeted. How does the Glynn-Johnson 90 Series jamb bracket mount?
The 90 Series lands on the jamb with an offset jamb bracket as standard, which is also the piece that makes the function field-convertible. For flush frames Glynn-Johnson publishes a separate installation for the 90 Series surface overhead holders using an angle bracket for flush frame, covering the H, F, S and SE functions. Sort out which frame condition you have before ordering, because the bracket arrangement is what determines whether the arm lines up square to the door.
13) What is a lighter duty alternative to the Glynn-Johnson 90 Series for a low traffic interior door?
The Sargent 1540 is a standard duty surface mount door stop/holder with a 110 degree opening, carrying a medium duty rating at Grade 1 - a reasonable fit for an office or interior door that sees light cycling. The ABH 3400 Series is another surface mount overhead stop and holder, sized for 24" to 36" door frames. The Glynn-Johnson 90 Series is heavy duty commercial hardware built in heavy-gauge brass, 300 Series stainless steel, or steel, which is what puts it on entrances, stairwells, and exterior doors where corrosion resistance and cycle life matter more than a lighter unit can deliver.
14) What overhead stop and holder should I use for a warehouse or loading dock door instead of the Glynn-Johnson 90 Series?
The Norton Rixson 7 Series Checkmate is an industrial duty surface door stop and holder with a hold open function, rated heavy duty at Grade 1 and built for abusive openings; the Norton Rixson 10 Series Checkmate surface stop/holder with slide track arm is another Grade 1 heavy duty option. The Glynn-Johnson 90 Series is also heavy duty and is specified for industrial and warehouse facilities, with the H hold-open function for doors that need to stand open during loading and the S stop-only function where the door should never be held. Its brass and 300 Series stainless steel construction is the choice where a dock door sees weather and washdown.
15) Can I get a Glynn-Johnson 90 Series overhead stop to match the dark bronze hardware already on my building?
Yes. SP313 powder coat dark bronze and US10B oil rubbed bronze both cover the dark bronze look, with SP10 powder coat bronze and US10 satin bronze available if your existing hardware is the lighter bronze. The full range is twelve finishes: 625 chrome-like coating, US3 polished brass, US4 satin brass, US10 satin bronze, US10B oil rubbed bronze, US32 polished stainless, US32D satin stainless steel, SP4 powder coat brass, SP10 powder coat bronze, SP28 powder coat aluminum, SP313 powder coat dark bronze and SPBLK powder coat black. Match to the finish code on your existing hardware rather than to the color name, since bronze reads differently as a powder coat than as a plated finish.
16) The overhead stops on my other doors are bronze - will a Glynn-Johnson 90 Series match, or do I need a different brand?
The Glynn-Johnson 90 Series carries bronze options directly: US10 satin bronze and US10B oil rubbed bronze in plated finishes, plus SP10 powder coat bronze and SP313 powder coat dark bronze, alongside brass finishes US3 polished brass and US4 satin brass and stainless finishes US32 polished stainless and US32D satin stainless steel. The Sargent 590 is a heavy duty overhead surface mount door stop/holder built in bronze if the existing units are Sargent and the goal is to keep one manufacturer across the building. For matching an existing look across mixed doors, the 90 Series finish range is wide enough to hold the same appearance while standardizing the hardware itself.
