Dormakaba 8956-AF89P-FC-SN1-689 – Frequently Asked Questions

1) Does the DORMA 8956 need to be ordered left hand or right hand?
No handing to specify. The 8956 is non-handed and ships tri-pack, meaning the same closer covers regular arm (pull side), top jamb, and parallel arm (push side) mounting. You decide the mounting at the door, not on the order form.
2) What mounting hardware comes with the DORMA 8956 door closer?
Sex nuts sized for a 1-3/4 inch door are included, so the closer through-bolts a standard commercial 1-3/4 inch leaf without you sourcing fasteners separately. Sex bolts are what you want on a hollow metal or wood door in high traffic, since wood screws pull out over time. If your door is a thickness other than 1-3/4 inches, the supplied fasteners will not be the right length.
3) Is the DORMA 8956 a hold open closer?
No, it is the non-hold open flat arm version. The door closes every time it is released, which is what you need on a fire rated opening or any door that has to self-close and latch. If you want the door to stand open at a set degree, this is the wrong arm; a hold open closer such as the Accentra 51 Series or the Orca BHDC1958 hold open version is the version to buy instead.
4) Is the DORMA 8956 Grade 1 and how many cycles is it rated for?
ANSI/BHMA Grade 1, tested to 10,000,000 cycles. For a spec writer or facilities buyer that is the top commercial grade with a heavy duty cycle count behind it, suitable for a school corridor, hospital, or entry door that swings all day. If your spec sheet calls for Grade 1 heavy duty surface closers, the 8956 meets it.
5) My spec calls for a slide track arm. Can the DORMA 8956 be used?
No. The DORMA 8956 is furnished with a flat arm non-hold open arm and will not satisfy a slide track callout. The Corbin Russwin DC5230 Series is a Grade 1 surface closer with a slide track arm as standard in a pull side mounting for 1-3/4 inch doors. If the drawing instead calls for a double lever regular arm on the pull side, the Corbin Russwin DC6200 and DC8200 Series are both Grade 1 surface closers in that configuration for 1-3/4 inch doors.
6) What is a straight equivalent to the DORMA 8956 closer for a heavy duty Grade 1 opening?
The DORMA 8956 is a heavy duty, Grade 1 surface closer rated for 10,000,000 cycles with adjustable spring size 5 to 6. The closest peers on the same footing are the BEST EHD9000 Series extra heavy-duty surface closer with adjustable spring sizes 1-6, Grade 1, and the BEST HD8000 Series heavy duty surface closer, also Grade 1. Falcon SC71A is another heavy duty Grade 1 surface-mount closer, as is the Sargent 1431 Powerglide with adjustable spring power and the Sargent 281 Powerglide in cast iron. All of these carry the same Grade 1 certification and heavy duty rating the 8956 does, so any of them holds the same class of opening.
7) I need a hold open arm instead of the 8956 non-hold open arm. What should I order?
The DORMA 8956 ships with a flat arm non-hold open arm in a tri-pack. For an opening that has to stand open, the Accentra 51 Series is a tri-packed hold open arm closer covering size 1-6, and the Orca Hardware BHDC1958HO/PA is a hold open closer with a parallel bracket for 1-3/4 inch doors. Stanley Security A45-501HL is a long hold open arm closer in a top jamb application. Choose the hold open peer rather than adding a stop to a non-hold open closer.
8) Which closers besides the DORMA 8956 give me all three mountings out of one box?
The DORMA 8956 is supplied as a tri-pack with a flat arm non-hold open arm, so one box covers the mounting options. Peers packed the same way include the Accentra 1101BF with tri-pack mounting and adjustable spring sizes 1-4, the Accentra 2701 Series with tri-pack mounting and adjustable spring sizes 1-6, the Arrow DCN325 with regular and parallel arm tri-pack and adjustable spring size 1-6, and the Calibre CA9901 with a tri-pack arm in size 2-5. Dexter DCH1000 is a Grade 1 tri-mount closer that can be regular, parallel, or top jamb mounted and comes with a full cover, and Norton Rixson 8501A is a Grade 1 tri-mount closer with an adjustable size 1-6 spring.
9) The job needs a delayed action closer. Does the DORMA 8956 do that?
The DORMA 8956 is a flat arm non-hold open closer with adjustable backcheck and full range spring power adjustment; delayed action is a separate function. For that, the Orca Hardware BHDC1958DA/PA is a delayed action closer with a regular arm and parallel bracket for 1-3/4 inch doors, and the Orca Hardware BHDC2011DA/PA is the same delayed action configuration in the BHDC2011 Series. Backcheck and delayed action control different parts of the swing, so do not treat the 8956 backcheck adjustment as a substitute for a delayed action requirement.
10) Will a Grade 2 closer work where the DORMA 8956 is specified?
Not if the spec is written to Grade 1. The DORMA 8956 is ANSI/BHMA Grade 1 certified and heavy duty. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer and the Falcon SC91A is a Grade 3 light duty cast aluminum closer, so neither meets a Grade 1 callout. If you want a Cal-Royal that stays at Grade 1, the 500S is a Grade 1 barrier free closer with adjustable back-check, the 700S is a Grade 1 dual valve sized closer with an adjustable tube arm, and the N900PBF is a Grade 1 barrier free hydraulic surface closer.
11) Is a size 1-4 closer an acceptable substitute for the DORMA 8956?
Only if the door is small enough. The DORMA 8956 is adjustable size 5 to 6 for doors up to 180 pounds, which is the upper end of the spring range. The Accentra 1101BF covers adjustable spring sizes 1-4 and the Arrow DCN314 covers adjustable spring size 1-4, so neither reaches into the 5-6 band the 8956 is set up for. To keep the top of the range, look at closers that go to 6, such as the Accentra 2701 Series at sizes 1-6, the Arrow DCN325 at size 1-6, the BEST EHD9000 at sizes 1-6, the Norton Rixson 8501A at size 1-6, or the Imperial USA TC4300 at size 1-6.
12) Will the DORMA 8956 stop the door slamming into the wall on a windy entrance?
That is what the backcheck is for, and the 8900 Series backcheck is adjustable by valve so you can set how hard it cushions the swing. There is also a separate backcheck positioning adjustment for parallel arm mounting, so a push side install cushions over the same range as a pull side or top jamb install. On a wind exposed entry with a 48 inch leaf, that is the setting that saves the door and the adjacent wall.
13) I need one closer model to standardize across a whole building. Does the 8956 cover most of my doors?
Partly. The 8956 covers the heavy end, sizes 5 to 6, doors up to 48 inches and 180 lbs, so it fits entrances and oversized leaves. It does not adjust down for narrow interior doors. If you want one adjustable model to cover a broader range of openings, look at a full size 1-6 closer such as the Accentra 2701 Series, the BEST EHD9000, or the Imperial USA TC4300, all of which cover sizes 1 through 6 on one body.
14) Can the DORMA 8956 mount on the push side of the door?
Yes. Tri-pack means the box supports parallel arm (push side), regular arm (pull side), and top jamb mounting. Push side parallel arm is the usual choice when the closer has to sit inside the room for security or when the pull side has no room for the arm. The 8900 Series carries a dedicated backcheck positioning adjustment for parallel arm so you do not lose backcheck range in that configuration.
15) I need an ADA barrier-free closer. Which options match the DORMA 8956 on that?
The DORMA 8956 is ADA compliant and, with its fully adjustable spring, meets barrier-free accessibility requirements. Peers described the same way include the Cal-Royal 500S Grade 1 barrier free closer with adjustable back-check, the Cal-Royal N900PBF barrier free Grade 1 hydraulic surface closer, the Calibre CA9901 tri-pack arm size 2-5 ADA closer, the Calibre CA4001 adjustable spring tension ADA hydraulic closer, the Imperial USA TC4300 Grade 1 heavy duty size 1-6 ADA closer, and the LCN 1250 in sizes 1-5. Of these, the Imperial TC4300 is the one that also carries a heavy duty rating like the 8956.
16) The opening is a low-traffic interior door. Is there a lighter closer than the DORMA 8956?
The DORMA 8956 is a heavy duty closer built for institutional and high-traffic commercial use. On a light-traffic interior door, the lighter-rated peers are the BEST SL6000 Series, a Grade 1 light duty surface closer with adjustable spring sizes, the Norton Rixson 160 Series light commercial closer, Grade 1 light duty, and the LCN 1250 Series light duty closer in sizes 1-5 with all-weather fluid and ADA compliance. Arrow DC314 is another Grade 1 light duty option. The BEST HD7000 Series sits between them as a Grade 1 medium duty closer with adjustable spring power and backcheck control.
17) The DORMA 8956 comes with a full cover. Which comparable closers come without one?
The 8956 8900 Series uses a narrow projection full cover over the aluminum body. Among the peers, the Arrow DCN314 and Arrow DCN325 are both supplied less cover with a regular and parallel arm tri-pack, and the Dexter DCH4000 Series is a Grade 1 tri-mount closer with no cover called out, while the Dexter DCH1000 Series is the tri-mount version with a full cover. Design Hardware also splits this way: the 316 Series is furnished with a cover, while the 116 and 416 Series are heavy duty closers with a tri-packed non-hold open arm.
18) Which closers look like alternatives to the DORMA 8956 but will not do the job?
A few items sit next to surface closers in a search and are not one. The Arrow DCN500DP is a parallel drop plate for the DCN500, a mounting accessory rather than a closer. Stanley Security 327 is a heavy wardrobe pivot for 1-3/8 inch or 1-3/4 inch doors up to 150 pounds and Stanley Security 341 is a wardrobe pivot for flush recessed or overlay doors 1-1/8 inch to 1-3/8 inch; pivots carry the door, they do not close it. Stanley Security 57-0100 is a box of 100 steel machine screws for architectural hinges. None of these replaces the 8956, which is a heavy duty surface mounted closer rated for 10,000,000 cycles.
19) I am standardizing an aluminum storefront entrance. Is the DORMA 8956 the right closer or is there a closer built for that?
The DORMA 8956 has an aluminum body and comes with sex nuts for a 1-3/4 inch door, which suits it to institutional and high-traffic commercial openings. If the entrance is aluminum storefront specifically, the Norton Rixson 1600 Series aluminum storefront closer is built for that application, Grade 1 heavy duty with tri-style mounting. The Norton Rixson 1601P is the medium duty Grade 1 tri-mount version of the 1600 Series with a 180 degree swing. The LCN 1460T is another Grade 1 heavy duty surface closer, finished in powder coat.
20) For a medium-traffic office door, what steps down from the DORMA 8956 without leaving Grade 1?
The DORMA 8956 is a heavy duty Grade 1 closer for institutional or high-traffic commercial use. On a medium-traffic opening that still has to be Grade 1, the Sargent 1131 is a Grade 1 adjustable surface closer for medium-traffic commercial applications and the Sargent 1331 is a Grade 1 medium duty closer with a universal aluminum body. Falcon SC81A is a Grade 1 medium duty cast aluminum closer and Falcon SC61A is Grade 1 light to medium duty. LCN 1450 is a medium duty closer in cast aluminum with spring sizes 1-6, and LCN 1261 is light to medium duty in cast iron with adjustable spring sizes 1-5.
21) I only need a standard arm or a parallel arm closer, not a tri-pack. What are the options against the DORMA 8956?
The DORMA 8956 is furnished as a tri-pack, so the mounting choice is made at install. If you would rather order the arm configuration outright, the Calibre CA5501 is a standard arm surface mount closer, Grade 1, and the Calibre CA8001P is a parallel arm size 1 ADA surface mount closer, also Grade 1. The Corbin Russwin DC3200 is a Grade 1 regular arm surface mounted closer for 1-3/4 inch doors.
22) What finishes does the DORMA 8956 surface closer come in?
Two: 689 aluminum and 695 dark bronze, both painted over an aluminum body. If you are standardizing a building, 689 is the common match for clear anodized aluminum storefront and 695 matches dark bronze frames, so pick to the frame rather than to the door.
23) Is the DORMA 8956 body cast iron or aluminum?
Aluminum. That keeps the closer lighter on the door and it will not rust on an exterior opening the way an unpainted iron body can, and the 689 and 695 finishes are painted over that aluminum body. If your specification specifically calls for cast iron, the Sargent 281 Powerglide and the LCN 1261 are cast iron surface closers.
24) Is the DORMA 8956 rated for residential use or commercial only?
Commercial. It is a heavy duty Grade 1 closer built for institutional and high traffic openings, and at size 5-6 the spring power is far heavier than a house door needs. On a multifamily building it belongs on the lobby and corridor entries, not on unit interior doors.
25) The DORMA 8956 is offered in 689 aluminum and 695 dark bronze. Which comparable closers cover a different look?
The 8956 is stocked in 689 aluminum and 695 dark bronze on an aluminum body. If the opening calls for a more traditional or residential appearance, the Accentra 1900 Series is a traditional surface mounted closer, and Deltana offers the DC10, DC40, DC50 and DC70 door closers. For a painted heavy duty commercial look on the same Grade 1 footing, the LCN 1460T is a heavy duty closer in a powder coat finish and the Sargent 281 Powerglide is a heavy duty cast iron closer.
