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

1) Will the DORMA 8956 door closer work on a left hand and a right hand door, or do I have to order handed?
The 8956 closer body is non-handed, so one unit covers either hand on most of the arm options. The exception is the double egress track arm, which is handed: order TDEH-LH for left hand or TDEH-RH for right hand. Every other arm choice (FTH, JTH, PTH, TH) is hand-neutral.
2) What is the difference between the FTH, JTH, PTH and TH arms on the 8956?
They differ by where the closer body and track land on the opening. TH mounts the closer on the door with the track on the frame, pull side. FTH is pull side with the closer frame mounted into a flush track condition, JTH is pull side with the closer frame mounted for a jamb track. PTH flips it to the push side with the closer soffit mounted, which is what you use when nothing can show on the corridor side of the door. TDEH is the double egress version, frame face mounted on the pull side and handed. All of them are hold open track arms.
3) Does the DORMA 8956 come with mounting screws, and what door thickness are they for?
Sex nuts are supplied, sized for a 1-3/4 inch door. That's the standard commercial door thickness, so on a typical hollow metal or solid core leaf you're covered out of the box. Through-bolting with sex nuts is also what you want on a high traffic door, since wood screws into a hollow metal skin pull out over time.
4) Is the DORMA 8956 ADA compliant for opening force?
Yes. The 8956 is ADA compliant and the fully adjustable spring lets you dial the power down to meet barrier-free opening force requirements, while backcheck stays available to protect the door on a hard swing.
5) Is the DORMA 8956 rated for high traffic entrances?
It is tested to 10,000,000 cycles and carries ANSI/BHMA Grade 1 certification, classed heavy duty and commercial. That cycle count is what you want on a main entrance, stairwell or a heavily used corridor door rather than a light duty closer that will need replacing.
6) I need to close a pair of double egress doors. Which 8956 do I order?
Double egress needs the TDEH track arm, and it is handed: TDEH-LH on the left hand leaf and TDEH-RH on the right hand leaf, both pull side with the closer frame face mounted. So a pair takes one of each, not two of the same part.
7) 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 same mounting approach as the DORMA 8956 slide track hold-open closer. The DORMA 8956 is also Grade 1 and is built to a 10,000,000 cycle rating with hold-open track arm options including flush track, jamb track, push side track, and double egress track in left and right hand. The DC5230 is listed for 1-3/4 inch doors.
8) I need a hold-open closer but not a track arm. What are the alternatives to the DORMA 8956?
Two hold-open arm closers that mount with a conventional arm are the Accentra 51 Series, supplied with a tri-packed hold open arm in sizes 1 through 6, and the Orca Hardware BHDC1958 hold open version with parallel bracket, listed for 1-3/4 inch doors. The Stanley Security A45-501HL uses a long hold open arm for top jamb mounting. The DORMA 8956 achieves hold-open through the slide track itself, in flush track, jamb track, push side, or double egress configurations.
9) Should I use a slide track closer or a regular parallel arm closer?
A slide 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 gets abused or looks wrong. A conventional regular or parallel arm projects off the door but generally gives you more mechanical advantage and easier field adjustment. If your drawing just calls for a tri-mount surface closer, something like the Corbin Russwin DC8200 Series with a double lever regular arm or the Sargent 1431 Powerglide heavy duty closer covers that; if the spec says slide track, the 8956 is the heavy duty answer.
10) Do I need the delayed action option on a slide track hold open closer?
Delayed action is a separate ordering choice on the 8956, yes or no. Take it where people need extra time to get through the opening: patient room doors, classroom exits, carts and wheelchairs, loading corridors. It holds the door near full open for a few seconds before the close cycle starts. Hold open already lets you park the door, so if the door is either fully parked or swinging shut, the standard non-delayed version is enough.
11) What cover options are there, and which one holds up in a school or dorm?
Three covers: the standard full plastic cover (FC), a full plastic slotted cover (FCSL), and a full metal cover (FMC). In dorms, schools and detention-adjacent corridors the full metal cover is the one to order, since plastic covers get kicked off and go missing. The slotted version is used where the arm or spindle location needs the clearance.
12) What other heavy duty Grade 1 closers could I use instead of the DORMA 8900 Series?
For a heavy duty Grade 1 surface closer, ZenSupply also carries the BEST HD8000 Series and the extra heavy duty BEST EHD9000 Series, the Falcon SC71A, the Sargent 1431 Powerglide and 281 cast iron closers, and the LCN 1460T. The thing to check is the arm: the 8956 is a slide track hold open, while most of those are conventional tri-mount or regular arm closers. If the slide track look is what the job needs, the closest peer here is the Corbin Russwin DC5230, a Grade 1 slide track arm closer for pull side mounting on 1-3/4 inch doors.
13) Is a size 5 to 6 closer overkill for a standard interior office door?
Usually yes. With an adjustable range of size 5 to 6 and a 180 lb door rating, the 8956 is built for large or heavy leaves and exterior openings. On an ordinary light interior door a medium or light duty closer is the better match, for example the BEST HD7000 Series (medium duty, Grade 1), the Sargent 1131, or the light duty LCN 1250 with spring sizes 1 to 5.
14) Can the 8956 be used where the arm must not show on the corridor side of the door?
Yes, order the PTH arm. It puts the track hold open on the push side with the closer soffit mounted, so the closer sits up under the head of the frame instead of on the visible face of the door. The FTH, JTH, TH and TDEH arms are all pull side.
15) Is a light duty closer like the Arrow DCN325 a substitute for the DORMA 8956?
They serve different traffic levels. The Arrow DCN325 is a Grade 1 surface closer rated light duty, supplied less cover with a regular or parallel tri-pack arm and adjustable spring size 1 through 6; the Arrow DC314 is likewise Grade 1 light duty. The DORMA 8956 is a heavy duty Grade 1 closer rated for 10,000,000 cycles at closer size 5 to 6, for doors up to 180 pounds, and comes with a full cover, with plastic, slotted plastic, and metal cover choices.
16) What is a simpler closer than the DORMA 8956 for a medium traffic interior door?
For medium traffic, the Sargent 1131 and Sargent 1331 are Grade 1 medium duty adjustable surface closers, the BEST HD7000 Series is a Grade 1 medium duty closer with adjustable spring power and backcheck control, and the Norton Rixson 8501A is a Grade 1 medium duty tri-mount closer with adjustable size 1 through 6 spring. The DORMA 8956 is a heavy duty Grade 1 unit intended for institutional and high-traffic commercial openings, with an aluminum body and adjustable backcheck.
17) Which alternatives to the DORMA 8956 also offer a delayed action option?
The Orca Hardware BHDC1958 delayed action version with parallel bracket and the Orca Hardware BHDC2011 delayed action version both use a regular arm with parallel bracket and are listed for 1-3/4 inch doors. The DORMA 8956 offers delayed action as a yes or no selection combined with its slide track hold-open arm, and the closer is non-handed except in the double egress track configurations, which are specified left hand or right hand.
18) For an aluminum storefront entrance, is the DORMA 8956 or the Norton Rixson 1600 the better fit?
The Norton Rixson 1600 Series is described as an aluminum storefront door closer with tri-style mounting, heavy duty and Grade 1, so it is purpose-named for narrow stile aluminum entrances. The DORMA 8956 is a heavy duty Grade 1 closer with an aluminum body, a narrow projection full cover and slide track arm, supplied with sex nuts for a 1-3/4 inch door and available in painted finishes including 689 aluminum, 690 and 695 dark bronze, 691 light bronze, 693 black, and 696 satin brass.
19) Does a Grade 2 closer like the Cal-Royal 400 work in place of the DORMA 8956?
Not where a Grade 1 specification is called out. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer. If a Grade 1 Cal-Royal is needed, the 500S is Grade 1 barrier free with adjustable back-check, the 700S is a Grade 1 dual valve sized closer with adjustable tube arm, and the N900PBF is a Grade 1 barrier free surface closer. The DORMA 8956 is ANSI/BHMA Grade 1 and ADA compliant with a fully adjustable spring.
20) What finishes does the DORMA 8956 painted closer come in?
Six painted finishes: 689 aluminum, 690 dark bronze, 691 light bronze, 693 black, 695 dark bronze and 696 satin brass. If you're matching existing closers in a building, pull the three digit number off the old cover rather than going by eye, since 690 and 695 are both called dark bronze.
21) What is the 8956 closer body made of?
Aluminum, with a painted finish over it. That matters for exterior and coastal openings where a cast iron body will rust once the paint is chipped. If you specifically want a cast iron body, the Sargent 281 Powerglide is the cast iron heavy duty option.
22) What heavy duty closers can I standardize on across a facility alongside the DORMA 8956?
Heavy duty Grade 1 surface closers to pair with the DORMA 8956 include the LCN 1460T in a powder coat finish, the Falcon SC71A, the Sargent 281 Powerglide cast iron closer, and the BEST EHD9000 Series with adjustable spring sizes 1 through 6. The Design Hardware 116 and 416 Series are heavy duty closers supplied with a tri-packed non-hold open arm, which suits openings where hold-open is not wanted while the DORMA 8956 covers the hold-open track positions.
23) Is the Arrow DCN500DP drop plate an alternative to the DORMA 8956?
No. The Arrow DCN500DP is a parallel drop plate for the DCN500 closer, a mounting bracket rather than a closer body. The DORMA 8956 is a complete surface mounted heavy duty closer with a slide track hold-open arm, sized 5 to 6 for doors up to 180 pounds, and is supplied with sex nuts for a 1-3/4 inch door.
