Glynn-Johnson 101H-US32D – Frequently Asked Questions
1) What is the difference between the H, HP, F, S and SE functions on a Glynn-Johnson 100 Series overhead holder?
Five functions are offered: H hold-open, HP internal hold-open, F friction hold-open, S stop-only, and SE special stop-only. Pick by whether the door should ever stay open on its own. H and HP catch and hold the leaf at the stop point until someone pulls it clear, which is what you want on a receiving corridor or a classroom door that gets propped every morning. F holds by friction rather than a positive catch, so the door can be pushed or pulled out of the hold with steady pressure. S and SE only arrest the swing and never hold, which is the right call on any door that has to close and latch behind traffic. Ordering a hold-open onto a door that must self-close is the most common mistake on overhead hardware.
2) Can I set a Glynn-Johnson 100 Series concealed stop to stop the door at 90 degrees?
Ninety degrees is inside the range. Glynn-Johnson supplies templates that allow variable mounting positions from 85 to 110 degrees of opening, so you choose the stop point when you lay out and drill, not afterward. That matters on the job: decide how far the door needs to swing before you machine the door and frame, because the position is set by which template location you mount to. Common reasons to hold it back toward 85 degrees are a return wall, a radiator, or millwork just past the door.
3) Will a Glynn-Johnson 100 Series concealed stop work on continuous hinges, swing clear hinges, or a double acting door?
All three. The 100 Series is built to install on conventional butt hinges, pivots, continuous hinges, swing clear hinges and numerous specialty hinges, and it works on single acting and double acting doors. That is the reason it turns up on healthcare and education jobs, where swing clear hinges on patient room doors and continuous hinges on abused corridor doors would otherwise force a different stop for every opening. Sizing still depends on the hinge type, so a center hung pivot door reads a different door opening range than a butt hinged one.
4) Concealed or surface mounted overhead stop, which one do I want on an existing door?
A concealed unit like the Glynn-Johnson 100 Series mortises into the top edge of the door with a bracket at the head frame, so nothing shows when the door is closed and there is nothing on the face for people to grab or vandalize. The tradeoff is machining: on doors already hung you are pulling the leaf and cutting a pocket in the top rail, which is fine on a new install or a shop-prepped door and awkward on an occupied building. If you cannot machine the door, go surface mounted instead, such as the Norton Rixson 10 Series Checkmate surface stop and holder, which screws to the face of the door and the frame.
5) What is the closest heavy duty concealed overhead stop and holder to the Glynn-Johnson 100 Series?
Two peers sit in the same class. The Norton Rixson 1 Series Checkmate is a heavy duty, Grade 1 concealed door stop and holder with a 110 degree opening, and the Sargent 690 is a heavy duty overhead concealed door stop/holder with ANSI Grade One compliance. The Dormakaba DORMA 900 Series is a third heavy duty stops and holders family. The Glynn-Johnson 100 Series itself is a heavy duty, concealed mount overhead stop and holder for commercial openings, with provided templates that allow mounting positions from 85 to 110 degrees of opening and five function choices - hold-open (H), internal hold-open (HP), friction hold-open (F), stop-only (S), and special stop-only (SE). If the specification calls out a concealed heavy duty unit and the schedule permits an equal, those are the units to price against each other.
6) The door and frame cannot take a concealed overhead stop - what mounts on the surface instead?
The Norton Rixson 10 Series is the surface-mounted route. The 10-236 Checkmate is a surface door stop and holder with an adjustable hold-open feature, the 10-346 Checkmate is a surface stop and holder, and both are medium duty. The 10-336 is a standard duty, Grade 1 overhead stop with adjustable opening control. All of them attach to the face of the door and the frame, so no channel has to be cut into the door top rail. The Glynn-Johnson 100 Series is a concealed mount unit, which means the arm and channel are morticed into the door and the door has to be prepped for it - on a hollow metal or wood door already hung, with no concealed prep, the surface Norton Rixson units are the ones that go on without reworking the door.
7) Is the Glynn-Johnson 100 Series overhead stop handed? Do I need a left hand and a right hand version?
The 100 Series is non-handed. One unit works on a left hand or a right hand door with no special ordering, so if you keep spares on a shelf for a portfolio of buildings you stock one part per size, function and finish instead of two. That also means you can pull a unit for an emergency repair without checking which way the door swings first.
8) The door already has a closer with a stop in the arm. Do I need an overhead stop too?
Running both is the intended arrangement for the 100 Series, which is designed to work in conjunction with surface-applied door closers. The overhead stop takes the impact of the door being thrown open, which is what a closer arm stop is least suited to absorbing, and Glynn-Johnson states the 100 Series is engineered for improved compatibility with closers and reduced wear on the door hardware over its life. On entrance and vestibule doors that get wind loaded, that split of duties is the difference between replacing a closer every couple of years and not.
9) Is a heavy duty concealed overhead stop worth it over a standard duty one on a school or lobby door?
On a door that gets thrown open all day, yes. The Glynn-Johnson 100 Series is a heavy duty unit and covers openings from 18 inches through 54 inches in six sizes, so one series handles a whole building. Standard duty concealed stops are usually built to a narrower slice of openings: the Don-Jo 3023 is a standard duty concealed stop for 30 inch doors, the 3024 for 36 inch doors, and the DORMA 711F is a standard duty concealed friction stop for a 21 to 27 inch opening. Those are reasonable on a light interior door in an office suite. For entrance, vestibule and high traffic corridor doors, heavy duty is the specification that stops the callbacks.
10) Can I match a Glynn-Johnson 100 Series overhead holder to the finishes already in my building?
Eleven finishes are offered. Plated: US3 polished brass, US4 satin brass, US10 satin bronze, US10B oil rubbed bronze, US32 polished stainless and US32D satin stainless steel. Powder coat: SP4 brass, SP10 bronze, SP28 aluminum, SP313 dark bronze and SPBLK black. US32D satin stainless is the usual match for commercial lever and closer hardware, and SP28 and SP313 are the ones that pick up aluminum and dark bronze storefront framing. Anything visible on a concealed stop is the jamb bracket, so match it to the frame and the closer rather than to the lockset if those differ.
11) Will these hold up on an exterior entrance door in a coastal or wash-down environment?
Specify the brass or 300 Series stainless steel construction if corrosion is the concern. Glynn-Johnson offers the 100 Series in heavy-gauge brass, 300 Series stainless and steel, and states that the brass and 300 Series stainless versions give the highest corrosion resistance for varied weather conditions and demanding environments. Steel is the economical choice for dry interior openings. Since the working parts of a concealed stop sit in a pocket in the top of the door where moisture collects and nobody inspects, the material choice matters more here than on hardware you can see.
12) Do I still need a floor stop or wall bumper if I install an overhead stop?
No. An overhead stop arrests the door at the head, so it does the job on the openings where the other two options fail: a door that opens into a corridor with no wall behind it, a vestibule where a floor stop would sit in the traffic path, or a lobby where a floor mounted stop is a trip hazard and a maintenance item. The Glynn-Johnson 100 Series adds hold-open functions on top of that, which a wall bumper cannot do at all. It stops the swing between 85 and 110 degrees depending on where you mount to the template.
13) Is a standard duty concealed overhead stop a drop-in substitute for a heavy duty one?
They are different classes of unit, so check the duty level before swapping. The Don-Jo 3023 and 3024 concealed overhead door stops are standard duty, the DORMA 711F concealed friction stop is standard duty, the Sargent 1530 concealed mount door stop/holder is medium duty with a 110 degree opening and a Grade 1 rating, and the Norton Rixson 10-236 and 10-346 surface Checkmate units are medium duty. The heavy duty concealed group is the Glynn-Johnson 100 Series, the ABH 1000 Series concealed mount overhead door stop, the Norton Rixson 1 Series Checkmate, the Sargent 690 and the DORMA 900 Series. On a corridor or entrance door being specified as heavy duty, a standard or medium duty unit is a different product, not the same part in another brand's box.
14) Which concealed overhead stops let the opening angle be adjusted after the unit is installed?
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 concealed mount stop and holders with adjustable opening control. On the Norton Rixson side, the 10-336 is a standard duty overhead stop with adjustable opening control. The Glynn-Johnson 100 Series sets its angle a different way: the provided templates allow variable mounting positions from 85 to 110 degrees of opening, so the stop point is chosen by where the unit is templated and mounted rather than dialed in afterward. If a facility wants the stop angle changed later without pulling hardware, the adjustable ABH and Norton Rixson units are the ones built for that.
15) I need a stop only, with no hold-open - which concealed overhead units are stop only?
The ABH 1000 Series is a heavy-duty concealed mount overhead door stop, and the Don-Jo 3023 and 3024 are standard duty concealed overhead door stops in satin stainless steel, built for 30 inch and 36 inch doors. The Glynn-Johnson 100 Series covers the same requirement without changing product families: it is ordered by function code, and S is stop-only while SE is special stop-only, alongside the hold-open (H), internal hold-open (HP) and friction hold-open (F) functions. That matters for a facility standardizing on one line - stop-only doors and hold-open doors can be ordered as the same series in the same finish rather than as two different brands.
16) Which concealed overhead stop can be matched to oil rubbed bronze or polished brass hardware?
The Glynn-Johnson 100 Series is ordered in eleven finishes: US3 polished brass, US4 satin brass, US10 satin bronze, US10B oil rubbed bronze, US32 polished stainless, US32D satin stainless steel, plus powder coats SP4 brass, SP10 bronze, SP28 aluminum, SP313 dark bronze and SPBLK black. The Don-Jo 3023 and 3024 concealed overhead door stops are supplied in satin stainless steel. On a lobby or common-area door where the exposed stop has to read the same as the levers and hinges in a bronze or brass finish, the 100 Series is the unit with a matching code; where the rest of the opening is satin stainless, either family lands in the right finish.
17) What is a friction hold-open overhead stop, and which units offer one?
A friction hold-open holds the door at the stop position by friction in the arm rather than a positive catch, so the door can be pushed out of hold without releasing a mechanism. The DORMA 711F is a standard duty concealed friction stop for a 21 inch to 27 inch door opening. The Glynn-Johnson 100 Series offers friction hold-open as its F function, and the same series also covers positive hold-open (H) and internal hold-open (HP) if the opening needs the door to stay put until it is deliberately released. Ordering the function code is how the behavior is chosen, so the door schedule can mix F and H doors within one series.
18) I ordered a stop-only overhead unit but the tenant now wants the door to hold open. Do I have to replace it?
Not necessarily. Glynn-Johnson publishes function conversion instructions for the 100 Series covering the H, HP, F, S and SE functions, so a unit already in the door can be looked at for conversion before you buy a new one. Ordering the function you want up front is still the cleaner path on new work, since conversion means getting back into the door.
19) How do the four ABH 1000 concealed overhead units differ from each other?
ABH splits the 1000 family by what the unit does at the stop. The 1000 Series is a heavy-duty concealed mount overhead door stop, the 1000A Series is a heavy-duty concealed mount overhead stop and holder with field-adjustable opening control, and the 1000RA and 1000SA Series are heavy-duty concealed mount stop and holders with adjustable opening control. The Glynn-Johnson 100 Series draws the same distinctions through function codes on one series - S and SE for stop-only, H, HP and F for the hold-open variants - with mounting positions templated from 85 to 110 degrees of opening. Anyone cross-referencing an ABH part number needs to carry the stop-versus-holder distinction across, since it is the difference between a door that catches open and one that only stops.
