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

1) Will the DORMA 8956 slide track closer handle a heavy exterior door?
The 8956 is a heavy duty surface closer rated for doors up to 180 lbs, with spring power adjustable across closer sizes 5 to 6. It is a commercial closer, ANSI/BHMA Grade 1, tested to 10,000,000 cycles. That covers institutional entrances and high-traffic openings where a size 3 or 4 residential-grade closer would wear out.
2) Do I need to order a left hand or right hand DORMA 8956?
The closer body itself is non-handed, so one unit works on either swing. Handing only enters the picture on the double egress track arms: TDE-LH and TDE-RH are ordered left hand or right hand, transom mounted. The other arm choices (FT, JT, PT) are not called out by hand.
3) What is the difference between the FT, JT and PT track arms on the 8956?
They differ by which side of the door the closer sits on and what it mounts to. JT puts the closer on the door with the track on the frame, pull side. FT is a pull-side flush transom application with the closer on the transom and the track on the door. PT is push side, transom mounted, again closer on transom and track on door. TDE-LH and TDE-RH are the double egress versions, transom mounted and handed.
4) Does the DORMA 8956 meet ADA opening force requirements?
Yes. The 8956 is ADA compliant and the fully adjustable spring lets you dial opening force down to meet barrier-free accessibility requirements on an accessible route.
5) I have a pair of double egress doors. Which 8956 do I order?
Order the TDE track arm, transom mounted, and specify it by hand: TDE-LH for the left hand leaf and TDE-RH for the right hand. On a double egress pair each leaf swings opposite the other, so you will normally need one of each rather than two of the same.
6) What is the closest slide track door closer to the DORMA 8956 from another manufacturer?
The Corbin Russwin DC5230 is the nearest match in intent: it is a Grade 1 surface door closer supplied with a slide track arm as standard for pull side mounting. The DORMA 8956 is also Grade 1 and is a slide track closer, offered with FT, JT, PT and double egress TDE-LH and TDE-RH track arm configurations and rated for 10,000,000 cycles at heavy duty. If you need transom mounted or double egress track geometry, those arm options come from the 8956 side.
7) If the opening does not need a slide track, what regular arm closer covers the same duty?
For a heavy duty Grade 1 opening with a conventional arm, the BEST HD8000 and the Sargent 1431 Powerglide are both heavy duty Grade 1 surface closers, and the Falcon SC71A is a heavy duty Grade 1 surface mount closer as well. The DORMA 8956 is a heavy duty Grade 1 closer built around track arm hardware, so it is the choice when the design calls for a concealed-look track on the door or frame rather than a projecting arm.
8) Why choose a slide track closer instead of a standard parallel arm closer?
A track arm keeps the hardware tight to the door and frame with no projecting elbow, which is why it gets specified in schools, healthcare and anywhere an exposed arm invites abuse or vandalism. The 8956 uses a narrow projection full cover to match. If you do not need the low profile and just want a tri-mount regular or parallel arm closer, a standard-arm Grade 1 unit like the Corbin Russwin DC3200 or the Norton Rixson 8501A covers that instead.
9) What mounting fasteners come with the 8956 closer?
Sex nuts sized for a 1-3/4 inch door ship with it, which is the standard commercial door thickness. Sex bolts are what you want on a hollow metal or wood door where you need to draw the closer through the door rather than rely on sheet metal screws.
10) Can I get a DORMA 8956 with delayed action for a wheelchair-accessible opening?
Delayed action is an ordering option on the 8956, yes or no. Specify the delayed action version where you want the door to hold near full open for a few seconds before it begins to close, which is common at accessible entrances and openings used with carts or gurneys.
11) What finishes does the painted DORMA 8956 come in, and can I match existing bronze hardware?
Six painted finishes: 689 aluminum, 690 dark bronze, 691 light bronze, 693 black, 695 dark bronze and 696 satin brass. There are two dark bronze options, 690 and 695, so pull the BHMA number off the closers already on your other openings rather than matching by eye.
12) Will the 8956 stop the door from slamming into an adjacent wall?
Backcheck is built in and adjustable by valve, which cushions the door before it reaches the end of its opening swing and protects the door, the closer and whatever is behind it. On parallel arm applications there is also a backcheck positioning adjustment so the cushion starts in about the same place as it would on regular or top jamb mounting. Backcheck is not a stop, so a wall or floor stop is still good practice.
13) What is a heavy duty alternative to the DORMA 8956 if I do not need a track arm?
Several Grade 1 heavy duty surface closers cover the same traffic level with conventional arms: the BEST HD8000 Series, the BEST EHD9000 Series with adjustable spring sizes 1-6, the Falcon SC71A, the Sargent 1431 Powerglide, and the LCN 1460T. If you specifically want the concealed-track look from another brand, the Corbin Russwin DC5230 is a Grade 1 slide track arm closer, pull side mounting.
14) Is a lighter duty closer enough for an interior office door, or do I need the 8956?
For a low-traffic interior door the 8956 is more closer than the opening needs, since it starts at spring size 5. Light duty Grade 1 options include the Arrow DC314, the BEST SL6000 Series and the Norton Rixson 160 Series; medium duty choices include the BEST HD7000, the Falcon SC81A and the Sargent 1131. Keep the 8956 for heavy exterior and high-traffic institutional openings where 10 million cycles matters.
15) How long is the slide track on the DORMA 8956?
The track is 48 inches. Confirm you have that much clear run along the head or the door face for the mounting style you picked, since the FT and PT arms put the track on the door leaf while JT puts it on the frame.
16) What should I look at if I need a hold open arm instead of the DORMA 8956 track arm?
The Accentra 51 Series is supplied with a tri-packed hold open arm, and the Orca Hardware BHDC1958HO/PA is a hold open door closer with a parallel bracket for 1-3/4 inch doors. The DORMA 8956 is offered in FT, JT, PT and double egress track arm configurations with delayed action available as an option, so specify one of the hold open models when a mechanical hold open position is required.
17) Which alternative should I consider for a medium traffic Grade 1 opening rather than the heavy duty 8956?
The Norton Rixson 8501A is a Grade 1 tri-mount surface closer with an adjustable size 1-6 spring at medium duty, the Sargent 1331 is a Grade 1 medium duty closer with a universal aluminum body, and the BEST HD7000 is a Grade 1 medium duty closer with adjustable spring power and backcheck. The DORMA 8956 carries the same Grade 1 certification but is a heavy duty, 10,000,000 cycle closer with an aluminum body and adjustable backcheck.
18) Does a Grade 2 closer like the Cal-Royal 400 work where the DORMA 8956 is specified?
Only if the specification allows Grade 2. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer, while the DORMA 8956 is ANSI/BHMA Grade 1 and heavy duty. Where the drawing calls out Grade 1, Cal-Royal's own Grade 1 options such as the 500S barrier free closer or the 700S dual valve sized closer are the closer match on rating.
19) What is a heavy duty alternative for an aluminum storefront entrance instead of the DORMA 8956?
The Norton Rixson 1600 Series aluminum storefront closer is heavy duty and Grade 1 with tri-style mounting, and the LCN 1460T is a heavy duty Grade 1 commercial closer in a powder coat finish. The DORMA 8956 is a heavy duty Grade 1 closer with an aluminum body offered in painted finishes including 689 aluminum, 690 and 695 dark bronze, 691 light bronze, 693 black and 696 satin brass.
20) Which barrier free closers compete with the DORMA 8956 on accessibility?
The Cal-Royal N900PBF is a Grade 1 hydraulic barrier free surface closer, the Cal-Royal 500S is a Grade 1 barrier free closer with adjustable back-check, and the Imperial USA TC4300 is a Grade 1 heavy duty size 1-6 ADA closer. The DORMA 8956 is ADA compliant with a fully adjustable spring that meets barrier-free requirements, and unlike those parallel and regular arm models it mounts with a slide track arm.
21) Can I get a metal cover on the DORMA 8956 instead of plastic?
Three cover choices: the standard full plastic cover (FC), a full plastic slotted cover (FCSL), or a full metal cover (FMC). Spec the metal cover on abuse-prone openings such as dorms, detention-adjacent corridors and public restrooms where plastic gets kicked off.
22) Is the DORMA 8956 body cast iron or aluminum?
Aluminum. The 8956 uses an aluminum body with a hydraulic control system, and the painted finish is applied over that. Some competing heavy duty closers use cast iron, such as the LCN 1261 and the Sargent 281, which is worth knowing if your spec calls out a body material.
23) Is the Arrow DCN500DP drop plate a substitute for anything on the DORMA 8956?
No. The Arrow DCN500DP is a parallel drop plate made for the Arrow DCN500 closer, not a closer itself and not track hardware. The DORMA 8956 ships as a complete track arm assembly in FT, JT, PT or double egress form, so a parallel arm drop plate for another brand's body has no role in that installation.
24) Are the Stanley wardrobe pivots an option in place of a DORMA 8956?
No. The Stanley 327 and Stanley 341 are wardrobe pivots for hanging doors, the 327 rated for 1-3/8 or 1-3/4 inch doors up to 150 pounds. They control how a door swings on its axis, not how it closes. The DORMA 8956 is a hydraulic surface mounted closer with adjustable spring power and adjustable backcheck for doors around 180 pounds, so a pivot is complementary hardware rather than a replacement.
