DORMA 712S Series

700 Series - Standard duty stops/holders

900 Series - Heavy duty stops/holders

Functions

S - Stop Only
F - Friction Stop
H - Stop/Hold

Stop only units (S function) are designed to limit the degree of door swing while providing a cushioned stop. These units are a good choice for use on labeled fire doors where hold open is prohibited.

Stop/Hold units (H function) function like stop only units with an added selective on/off hold open feature. An inconspicuous slot screw on the face of the track channel allows field engagement/disengagement of hold open. Stop/hold is recommended where non-labeled doors must be held in the open position.

Friction/Stop (F function) units provide a cushioned limiting stop and adjustable friction stay. The accessible screw on top of the slide shoe allows field adjustment of the friction. This option provides a method of holding non- labeled doors at multiple positions without readjustment. Available in 700/710 Series only.

Product details

Durable and visually pleasing

Separate stops and holders are the preferred method of limiting door swing. They are ideal where the use of wall or floor stops is precluded. The 700/900 Series high quality units are both durable and visually pleasing.

Highest quality materials

DORMA stops and holders are designed and manufactured from the highest quality materials to provide optimum service under heavy-duty use.

Different finishes available

A standard two-coat paint finish is the best choice to match sprayed DORMA door closers. Optional plated finishes are also available.

Several unit types available

Stop only units are designed to limit the degree of door swing while providing a cushioned stop. These units are a good choice for use on labeled fire doors where hold open is prohibited. Stop/Hold units function like stop only units with an added selective on/off hold open feature. Stop/hold is recommended where non-labeled doors must be held in the open position.

Dormakaba 712S 689 – Frequently Asked Questions

1) Can I use a concealed overhead stop on a labeled fire door?
A stop only unit like the 712S is the right pick there. The S function limits the swing and cushions the door at the end of travel with no hold open at all, which is what you want on a labeled fire door where hold open is prohibited. If you want hold open, that has to be a non-labeled opening, and you would order the H (stop/hold) or F (friction/stop) function instead.
2) What does the S in DORMA 712S mean, and how is it different from the H and F units?
S is stop only: it limits how far the door swings and cushions it, nothing more. H is stop/hold, same stop action plus a selective hold open you turn on or off in the field with a slot screw on the face of the track channel. F is friction/stop, a cushioned stop with an adjustable friction stay set by a screw on top of the slide shoe, so the door stays put at multiple positions. F is only offered in the 700/710 Series.
3) Is the DORMA 700 Series standard duty or heavy duty, and which should I spec?
The 700 Series is DORMA's standard duty stop and holder line; the 900 Series is the heavy duty line. For an interior office, classroom, or apartment door in normal traffic, standard duty is the correct spec. For an entry, a stairwell, a heavy exterior door, or anywhere the door gets thrown open hard, step up to the 900 Series or a heavy duty concealed unit such as the Glynn-Johnson 100 Series, the Norton Rixson 1 Series Checkmate, or the Sargent 690.
4) Concealed overhead stop or surface mounted overhead stop, which do I need?
Concealed units like the DORMA 712S mortise into the top of the door and the frame soffit, so almost nothing shows when the door is closed. That means the door and frame have to be prepped for the cutout, which is easy on a new door and a real job on an existing one. If the door is already hung and you cannot mill it, go surface mounted instead: the Glynn-Johnson 70 Series or 79 Series, or the Norton Rixson 10 Series, all mount on the face of the door and the frame with no mortising.
5) What overhead stop should I use instead of a DORMA 712S on a high traffic opening?
The 712S is a standard duty unit. Where the opening warrants a heavier unit in the same concealed mount arrangement, the Glynn-Johnson 100 Series is a heavy duty concealed overhead holder and stop that is non-handed, the Norton Rixson 1 Series Checkmate is a heavy duty concealed stop and holder with a 110 degree opening and carries Grade 1, and the Sargent 690 is a heavy duty overhead concealed stop/holder with ANSI Grade 1 compliance. The ABH 1000 Series is a heavy duty concealed mount overhead door stop that is fire rated, which is relevant if the opening is a labeled fire door.
6) What is the closest equivalent to a DORMA 712S concealed overhead stop from another manufacturer?
The DORMA 712S is a standard duty concealed mount overhead stop with a stop only function. The Don-Jo 3024 is the nearest match in kind: a standard duty concealed overhead door stop in satin stainless steel sized for 36 inch doors. Don-Jo also builds the 3023 in the same standard duty concealed configuration for 30 inch doors, so a 30 inch and a 36 inch opening are both covered. The 712S is finished differently, offered in 15 finishes from 605 bright brass through 693 black and 689 aluminum, where the Don-Jo units are satin stainless steel.
7) I need hold open, not just a stop. What replaces a DORMA 712S?
The 712S is the S function, stop only, which limits swing with a cushioned stop and no hold open. For a non-labeled door that must stay open, concealed stop and holder units include the Sargent 1530, a concealed mount stop/holder with a 110 degree opening, and the Norton Rixson 1 Series Checkmate concealed stop and holder, also at 110 degrees. The ABH 1000A, 1000RA and 1000SA Series are concealed mount overhead stop and holder units with adjustable opening control, the 1000A being field adjustable. Within the DORMA 700 Series itself the H function adds a selective on/off hold open engaged by a slot screw on the track channel face.
8) Which overhead stops are surface mounted rather than concealed like the DORMA 712S?
The 712S is a concealed mount unit, which is mortised into the door and needs the door prepped for it. If the door cannot be cut, surface applied units mount to the door face and frame instead: the Glynn-Johnson 70 Series is a heavy duty surface overhead holder and stop with an 85 to 110 degree hold-open range, the Glynn-Johnson 79 Series is an extra heavy duty surface unit, and the Norton Rixson 10 Series Checkmate is offered as a surface stop and holder in the 10-236 and 10-346 units. These are not drop-in for a concealed prep; the door and frame preparation is different.
9) What finishes does the DORMA 712S overhead stop come in, and which one matches a sprayed DORMA closer?
Fifteen finishes: 605 bright brass, 606 satin brass, 611 bright bronze, 612 satin bronze, 613 oil rubbed bronze, 618 bright nickel, 619 satin nickel, 625 bright chrome, 626 satin chrome, 689 aluminum, 690 dark bronze, 691 light bronze, 693 black, 695 dark bronze and 696 satin brass. The painted finishes (689, 690, 691, 693, 695, 696) are the two-coat paint DORMA uses to match sprayed closers, so pick from those if the stop has to sit next to a sprayed 689 or 690 closer on the same opening. The plated options are the brass, bronze, nickel and chrome numbers.
10) Can I add hold open to a DORMA 712S later if the tenant wants the door propped?
No. The 712S is a stop only unit; hold open is a different unit, not an accessory. The hold open feature lives in the H function model, where a slot screw on the track channel face lets you switch it on or off in the field. If there is any chance the opening needs hold open later, and the door is not fire labeled, order the stop/hold version up front.
11) Does an overhead stop replace the door closer, or do I still need one?
You still need the closer. The 712S controls how far the door opens and cushions the end of the swing; it does not close the door or control closing speed. DORMA sells the 700/900 Series stops and holders as a complement to their closer line, so on a typical commercial opening you are buying both: a closer for the close cycle and an overhead stop to protect the door, hinges and adjacent wall at the open end.
12) Is the Norton Rixson 10 Series a substitute for a DORMA 712S concealed stop?
Only in part, and it depends on which 10 Series unit. The Norton Rixson 10-336 is a standard duty overhead stop with adjustable opening control and carries Grade 1, which is a close functional match to the 712S stop only role. The 10-236 and 10-346 Checkmate units are surface mounted stop and holders at medium duty, so they do not drop into a concealed prep the way the 712S does. Confirm mount type before ordering against a concealed cutout.
13) I am standardizing overhead stops across a building. Which lines cover the most openings from one manufacturer?
For a single-source fleet, Glynn-Johnson spans duty levels and both mount types: the 100 Series heavy duty concealed non-handed units, the 410 Series medium duty concealed units, and the 70 and 79 Series surface units for doors that cannot be prepped. ABH covers the concealed side across the 1000, 1000A, 1000RA and 1000SA Series, the 1000 being fire rated and the A, RA and SA units adding adjustable opening control. The DORMA 700 Series carries the S stop only, H stop/hold and F friction stop functions and offers 15 finishes, so one line can match brass, bronze, nickel, chrome, aluminum and black hardware across a building.
14) Is this DORMA overhead stop suitable for commercial buildings or just residential?
The 712S is a commercial rated unit, part of DORMA's door control line that complements their door closers. It is built for the kind of repeated use you get in offices, schools, healthcare, and multi-family common areas, not sized as a residential item.
