Glynn-Johnson 793H-US26D – Frequently Asked Questions

1) Do I have to specify handing when ordering a Glynn-Johnson 79 Series overhead holder?
No handing to specify. The 79 Series is non-handed, so one unit covers left and right hand openings. That is why a property manager standardizing a building only has to stock by door width, model (hold-open or stop-only), and finish.
2) What is the difference between the 79 Series H and S models?
H is the hold-open version: the door parks open at the stop angle until you pull it free. S is stop-only, which arrests the door at the same angle but does not hold it there, so the closer takes it back shut. Pick S on anything you need to stay latched (corridors, stair doors, anywhere a closer must control the door), and H where you want the door propped for loading, cleaning, or airflow.
3) Can I install a 79 Series overhead stop without cutting into the door or frame?
Largely, yes. The 79 Series is a surface-applied unit: both the door bracket and the jamb bracket mount to the face, so it needs minimal door and frame prep compared with a concealed overhead stop that has to be mortised into the top rail and the frame soffit. That is what makes it a practical retrofit on existing openings where you are not pulling the door to a shop. Glynn-Johnson supplies templates covering many mounting positions and nearly all door types, including doors hung on conventional butt hinges and on specialty hinges.
4) What do I need to order with a 79 Series overhead stop for a thick door or a hollow metal door?
Four add-on options are available and they cover the usual install problems. SB-1 sex bolts through-bolt the door bracket on doors up to 2 inches thick; SB-2 does the same on doors 2 to 3 inches. Use those on mineral core, aluminum, or any door where screws alone will pull out under abuse. SOC gets you pin-in-socket security screws for openings where tampering is a concern, such as detention-adjacent or public restrooms. J adds an angle jamb bracket when the frame face does not give you a flat mounting surface square to the door.
5) Is there a lighter duty overhead door stop for an interior door that does not see heavy traffic?
Yes. The Don-Jo 3023 and Don-Jo 3024 are standard duty concealed overhead door stops in satin stainless steel, sized for 30 inch and 36 inch doors respectively. The Norton Rixson 10-336 is another standard duty overhead stop, with adjustable opening control and a Grade 1 rating. The Glynn-Johnson 79 Series is a heavy duty commercial unit built for high-traffic industrial and commercial openings, so the lighter units suit closets, offices and low-cycle interior doors where that build is more than the opening needs.
6) My spec calls for ANSI Grade 1 on the overhead stop. Which comparable units state a Grade 1 rating?
Four peers state Grade 1: the Sargent 690 heavy duty overhead concealed stop/holder, the Norton Rixson 1 Series Checkmate heavy duty concealed stop and holder, the Norton Rixson 10-336 standard duty overhead stop, and the Sargent 1530 medium duty concealed mount stop/holder with 110 degree opening. Of those, the Sargent 690 and Norton Rixson 1 Series are the two that pair Grade 1 with a heavy duty rating, matching the heavy duty class of the Glynn-Johnson 79 Series.
7) Should I use a surface overhead stop or a concealed one?
A surface unit like the 79 Series bolts to the face of the door and frame, so it installs on doors already hanging and it is straightforward to service or replace later. The tradeoff is that you see it. A concealed overhead stop hides in the top rail and frame soffit for a cleaner look, but it needs the door and frame machined for it, which usually means new doors or a shop. If aesthetics rule the opening, look at concealed units such as the Sargent 690, a heavy duty overhead concealed stop and holder, or the ABH 1000 Series. If speed of install and serviceability rule, stay surface.
8) When do I need the J angle jamb bracket on a Glynn-Johnson 79 Series stop?
The J option swaps in an angle jamb bracket, and Glynn-Johnson publishes separate installation instructions for the angle bracket version of the 79 Series H and S. You order it when the standard flat jamb bracket has nowhere to land square, which typically comes up on deep reveals or frame profiles that put the soffit out of reach. If the frame face is flat and standard, order the unit without a device option.
9) Which finish should I pick for an exterior door or a coastal building?
For weather exposure, the powder coat finishes are the practical pick: SP10 bronze, SP313 dark bronze, SP28 aluminum, SP4 brass, and SPBLK black. Glynn-Johnson builds the 79 Series in heavy gauge brass, 300 Series stainless steel, and steel, and it is the brass and stainless material options that carry the highest corrosion resistance, so specify one of those materials rather than steel on anything seeing salt air or standing weather. Plated architectural finishes are also offered: US3 polished brass, US4 satin brass, US10 satin bronze, US10B oil rubbed bronze, US26 polished chrome, and US26D satin chrome.
10) Can I use a 79 Series overhead stop on a door that already has a closer?
Yes, and that is the normal application. The 79 Series is built to work alongside door closers, and taking the shock of the swing at the overhead stop instead of at the closer arm reduces wear on the closer and the rest of the door hardware. On any high traffic opening with a closer, a heavy duty overhead stop is what keeps the closer from being used as the stop.
11) What is a heavy duty alternative to the Glynn-Johnson 79 Series surface overhead stop?
Staying surface mounted, the Norton Rixson 10 Series Checkmate is the closest cross-brand family, offered as a surface stop and holder with adjustable hold-open. Note the duty levels differ across that family: the 10-336 is standard duty and the 10-236 and 10-346 are medium duty, while the 79 Series is heavy duty. The DORMA 900 Series is another heavy duty stops and holders family. If you want a heavy duty unit and can accept concealed mounting, the Norton Rixson 1 Series Checkmate is Grade 1 heavy duty with a 110 degree opening.
12) Is the Don-Jo 3024 overhead stop a substitute for a Glynn-Johnson 79 Series?
Not on the same kind of opening. The Don-Jo 3024 is a standard duty concealed overhead stop for 36 inch doors in satin stainless, and the 3023 is the standard duty version for 30 inch doors. Both are concealed mount, so they need the door and frame machined, and both are standard duty. The 79 Series is heavy duty and surface applied. On a warehouse, school, or any door getting abused, the duty difference is the one that matters; the Don-Jo units suit lighter traffic where the look is the priority.
13) Is there another heavy duty stop and holder family that covers a range of openings the way the Glynn-Johnson 79 Series does?
The DORMA 900 Series is a heavy duty stops and holders family, so it covers the same duty class as the Glynn-Johnson 79 Series across a family of units rather than a single size. The 79 Series itself spans five door opening ranges, from 23 1/16 inch to 27 inch up to 45 1/16 inch to 54 inch on butt or offset pivots, with corresponding center hung ranges reaching 59 inches.
14) I need the hold-open angle to be adjustable in the field rather than fixed at installation. What are my options?
The ABH 1000A Series is a heavy duty concealed mount overhead stop and holder with field-adjustable opening control, and the ABH 1000RA and 1000SA Series are heavy duty concealed mount stop and holders with adjustable opening control. The Norton Rixson 10-336 also offers adjustable opening control in a standard duty unit. The Glynn-Johnson 79 Series works over an 85 to 110 degree hold-open and stop range and is ordered as either the H hold-open or S stop-only model.
15) Do the Norton Rixson 10 Series Checkmate surface units do the same job as a Glynn-Johnson 79?
They mount the same way but sit in a different duty class and function. The Norton Rixson 10-236 and 10-346 Checkmate surface units are medium duty and carry a stop product function, while the 79 Series is a heavy duty surface overhead holder and stop for high-traffic industrial and commercial openings, ordered as an H hold-open or an S stop-only. For a heavy duty surface application, the Norton Rixson 1 Series Checkmate is the closer match at heavy duty and Grade 1.
16) We are standardizing overhead door control across a building and want one unit in multiple finishes. How do the options compare?
The Glynn-Johnson 79 Series carries eleven finishes across one platform, including US3 polished brass, US4 satin brass, US10 satin bronze, US10B oil rubbed bronze, US26 polished chrome, US26D satin chrome, and powder coats in bronze, dark bronze, aluminum, brass and black, with heavy gauge brass, 300 Series stainless steel and steel material options. Among the comparables, the Don-Jo 3023 and 3024 concealed overhead stops are specified in satin stainless steel, which suits a facility standardizing on a single stainless look on lighter standard duty interior doors.
17) What is the difference between a friction stop like the DORMA 711F and a Glynn-Johnson 79 hold-open?
The DORMA 711F is a standard duty concealed friction stop covering a 21 inch to 27 inch door opening, so it controls the door by friction at the stop point. The Glynn-Johnson 79 Series H model is a dedicated hold-open unit working over an 85 to 110 degree range, and the S model is stop-only; both are heavy duty and surface applied with door and jamb brackets requiring minimal door and frame preparation.
18) Is the Glynn-Johnson 79 Series rated for industrial and high traffic commercial doors?
The 79 Series is a heavy duty, commercial rated overhead holder and stop, built for high traffic industrial and commercial openings. Typical placements are warehouses and industrial facilities, offices, schools, healthcare, retail, government buildings, and multi-tenant residential. For a facility standardizing on one stop across mixed door widths, the non-handed design and five door width ranges let you spec a single series building wide.
