Product details

It results in the perfect combination of durability, reliability, and appearance.

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

1) Will the DORMA 8956 closer work on a heavy exterior door, and how big a door can it handle?
The DORMA 8956 is a heavy duty surface closer with spring power adjustable across sizes 5 to 6, rated for doors up to 180 lbs. That puts it squarely on wide, heavy exterior and institutional openings rather than light interior doors. If your door is a standard 3-foot interior opening, a size 1-4 closer is the better match; the 8956 starts where most closers stop.
2) Do I have to order a left-hand or right-hand version of the 8956 closer?
No handing to specify. The 8956 is non-handed, so one unit covers both left and right swings. You choose the mounting (regular or top jamb) at install, not at the order.
3) Can the 8956 be parallel arm mounted on the push side?
The IS-Integra cushion arm version is built for regular arm and top jamb mounting. If your opening requires the closer on the push side with a parallel arm, this is the wrong arm configuration and you need the parallel arm version of the 8900 Series instead. The series itself does support parallel arm applications, including a backcheck positioning adjustment for them.
4) Is the DORMA 8956 certified Grade 1, and how many cycles is it tested to?
ANSI/BHMA Grade 1 certified, with a 10,000,000 cycle endurance rating. For a spec writer standardizing a high-traffic institutional building, that is the number that separates it from medium and light duty closers.
5) What mounting fasteners come with the DORMA 8956 closer?
It ships with sex nuts sized for a 1-3/4 inch door, which is the standard commercial door thickness. Sex nuts pull the closer through the door rather than relying on screws in the face, which is what you want on a heavy, high-cycle opening. If your door is thicker or thinner than 1-3/4 inches you will need different through-bolt hardware.
6) What is the closest heavy-duty Grade 1 surface closer to the DORMA 8956 from another manufacturer?
The DORMA 8956 is a heavy duty, Grade 1 surface mounted closer. The closest peers on those same two attributes are the BEST EHD9000 Series extra heavy-duty surface closer with adjustable spring sizes 1-6 and the BEST HD8000 Series heavy duty surface closer, both Grade 1. Falcon's SC71A Series is also a Grade 1 heavy-duty surface-mount closer, and Sargent's 1431 Powerglide is a Grade 1 heavy-duty surface closer with adjustable spring power. Any of those four sit in the same duty and grade class as the 8956.
7) The 8956 is more closer than I need for an interior office door. What is a lighter alternative?
The DORMA 8956 is a heavy duty closer sized 5 to 6 for doors around 180 lb. For lighter interior traffic, the BEST SL6000 Series is a Grade 1 light duty surface closer with adjustable spring sizes, the LCN 1250 Series is a light duty surface closer in sizes 1-5 and ADA compliant, and the Norton Rixson 160 Series is a Grade 1 light duty commercial surface closer with adjustable spring. For a middle step, the BEST HD7000 Series is a Grade 1 medium duty closer with adjustable spring power and backcheck.
8) I need a closer with size 1-6 adjustability rather than the 8956's size 5-6 range. What should I use?
The DORMA 8956 is an adjustable size 5 to 6 closer, built for the heavy end of the range. If the opening needs a broader span, the Accentra 2701 Series offers adjustable spring sizes 1-6 with tri-pack mounting, the Arrow DCN325 is a Grade 1 surface closer adjustable size 1-6, the Norton Rixson 8501A is a Grade 1 tri-mount closer adjustable size 1-6, and the Imperial USA TC4300 is a heavy duty size 1-6 ADA closer. Those cover light interior doors through heavy exterior leaves off one part number.
9) Which closers look like substitutes for the 8956 but will not hold up on a heavy high-traffic door?
The DORMA 8956 is rated heavy duty at 10,000,000 cycles, Grade 1. Several surface closers in the same aisle are built to a lighter standard: the Falcon SC91A is a Grade 3 light duty cast aluminum closer, the Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer, and the Arrow DC314 and DCN325 are Grade 1 but rated light duty. The Falcon SC81A and Sargent 1131 are Grade 1 medium duty. Also note that Stanley 327 and 341 are wardrobe pivots, not closers at all, despite showing a heavy duty rating.
10) Does the DORMA 8900 Series closer meet ADA opening force requirements?
Yes. The 8900 Series closer is ADA compliant and the fully adjustable spring lets you dial the opening force down to meet barrier-free accessibility requirements. That matters on any door in a path of travel in a school, healthcare, or government facility.
11) What is the backcheck on the 8900 Series for and can it be adjusted?
Backcheck slows the door near the end of the opening swing so wind or a hard push does not slam it into the adjacent wall or tear the arm off. On the 8900 Series it is adjustable by valve, so you set the intensity to the opening. Paired with the Integra cushion arm you get both a hydraulic check and a mechanical stop on the same door.
12) Is there an equivalent to the 8956 that holds the door open?
The DORMA 8956 uses the IS-Integra cushion arm, which is a cushion stop arm rather than a hold-open. If the opening needs the door to stay put, the Accentra 51 Series is an industrial closer with hold open and tri-packed mount options in sizes 1-6, the Orca BHDC1958HO/PA is supplied with a hold-open arm and parallel bracket, and the Stanley A45-501HL uses a long hold open arm in a top jamb application. For timed closing instead, the Orca BHDC1958DA/PA is a delayed action closer with regular arm and parallel bracket.
13) I need an ADA barrier-free closer like the 8956 for a public entrance. What else qualifies?
The DORMA 8956 is ADA compliant and meets barrier-free requirements through its fully adjustable spring. Comparable barrier-free options include the Cal-Royal 500S, a Grade 1 barrier free closer with adjustable back-check, the Cal-Royal N900PBF barrier free Grade 1 hydraulic surface closer, the Calibre CA4001 adjustable spring tension ADA hydraulic closer, and the Calibre CA9901 tri-pack arm size 2-5 ADA closer. The LCN 1250 is also listed ADA compliant in sizes 1-5.
14) Is there a slide track alternative to the 8956 arm for a cleaner look on the pull side?
The DORMA 8956 uses a flatform style arm in a regular or top jamb application. For a track instead of an exposed arm, the Corbin Russwin DC5230 is a Grade 1 surface closer with slide track arm standard, pull side mounting, for 1-3/4 inch doors. If a double lever regular arm on the pull side works, the Corbin Russwin DC6200 and DC8200 are both Grade 1 surface closers in that configuration, also for 1-3/4 inch doors, which matches the door thickness the 8956 sex nuts are supplied for.
15) For an aluminum storefront entrance, does the 8956 fit or is there a better-suited closer?
The DORMA 8956 is a heavy duty Grade 1 commercial closer with an aluminum body and adjustable backcheck to protect the door and adjacent structure, and it is non-handed. A closer built specifically for that opening is the Norton Rixson 1600 Series aluminum storefront door closer, heavy duty Grade 1 with tri-style mounting. LCN's 1460T is also a Grade 1 heavy duty surface closer in a powder coat finish for commercial entrances.
16) I want a cast iron closer body instead of the 8956's aluminum. What are my options?
The DORMA 8956 has an aluminum body and is offered in 689 aluminum and 695 dark bronze finishes. If cast iron is specified, the Sargent 281 Powerglide is a cast iron surface closer with heavy-duty construction, and the LCN 1261 is a surface closer with cast iron construction and adjustable spring sizes 1-5. Among cast aluminum peers, Falcon's SC71A heavy-duty and SC81A medium-duty closers are both Grade 1.
17) What finishes does the DORMA 8956 surface closer come in?
Two: 689 aluminum and 695 dark bronze, both painted. Those are the two standard architectural closer finishes, so matching existing hardware across a building is usually straightforward. The closer body itself is aluminum.
