Dormakaba STA-8916-ARP-FMC-SN1-630 – Frequently Asked Questions

1) Will a door closer hold up on a pool deck or a coastal building where everything else rusts out?
That's exactly what the DORMA STA8916 is built for. The STA Series takes the same closer platform and adds corrosion resistance for severe climates and corrosive exposure, with recommended applications including seashore and swimming pool areas, offshore oil rigs, ships, chemical plants, and sewage treatment facilities. Body substrate is aluminum. If you're replacing standard closers every couple of years on a natatorium or an oceanfront property, this is the version to spec.
2) Do I have to order a left hand or right hand DORMA STA8916 closer?
No handing to specify. The STA8916 is non-handed and mounts regular arm, top jamb, or parallel arm, so one unit covers whichever way the door swings and whichever side you have room on. For a property manager standardizing across a building, that means a single part number on the shelf instead of a left and a right.
3) What spring size does the STA8916 door closer cover, and will it handle a wide exterior entrance door?
Spring power on the STA8916 is field adjustable across sizes 1 through 6, and it is a heavy duty closer. Sizes at the top of that range are what you use on wide or heavy exterior openings, while dialing down toward the low end is how you get a lighter opening force on an interior door. You set it on the unit, not at the order form, so one closer covers a mixed run of doors in the same facility.
4) Is the DORMA STA8916 closer ADA compliant and Grade 1?
Both. The STA8916 is ANSI/BHMA Grade 1 certified and listed as ADA compliant. Adjustable spring power is what makes the ADA piece work in practice, since you can back the size down to meet the reduced opening force a barrier free opening needs and still keep the closer on the door. For institutional and MRO specs that call for a Grade 1 surface closer, this meets it.
5) What is the difference between the AR and ARP arm on the STA8916, and which one do I need?
Both are round form non-hold-open arms. The AR is the regular arm you use pulling side or top jamb; ARP is the parallel arm version for mounting on the push side of the door with the closer body on the door face and the arm running parallel to the head. If the door opens out into a corridor or the frame face gives you nothing to land on, parallel arm is the one. Pick the arm and the finish together when you order, since those are the two choices on the part.
6) Will the STA8916 stop the wind from slamming my door back into the wall?
Backcheck is standard on the STA8916, and both its intensity and the point in the swing where it kicks in are adjustable. That is the function that cushions a door being thrown open, which is the usual failure mode on exterior openings in wind. You also get separate sweep speed and latch speed adjustments, so you can slow the main swing while keeping enough latch speed to throw the bolt.
7) Which door closer should I use instead of a STA8916 if I need the door to hold open?
Both STA8916 arm choices, the AR round form arm and the ARP round form arm, are non-hold open arms. Where the opening needs to stand open, peers built with a hold open arm include the Accentra 51 Series industrial closer with hold open and tri-packed mount options in size 1-6, the Orca Hardware BHDC1958 Series hold open closer with parallel bracket, and the Stanley Security A45-501HL with a long hold open arm standard in a top jamb application. The STA8916 does offer optional delayed closing from maximum opening angle to approximately 70 degrees, which slows the door for a loaded cart or a wheelchair user without holding it open; if delayed action is what is actually wanted rather than true hold open, the STA8916 covers it, and the Orca BHDC1958 and BHDC2011 delayed action closers do the same on a non-hold open arm.
8) What is the closest equivalent to a DORMA STA8916 door closer from another manufacturer for a heavy duty Grade 1 opening?
The DORMA STA8916 is a heavy duty, Grade 1 certified surface mounted closer with adjustable spring power, adjustable backcheck intensity and positioning, and separate sweep and latch speed adjustment. The closest peers on the same duty and grade footing are the BEST EHD9000 Series extra heavy-duty surface closer with adjustable spring sizes 1-6, the BEST HD8000 Series heavy duty surface closer with Grade 1 certification, the Falcon SC71A heavy-duty surface-mount closer, the Sargent 1431 Powerglide heavy-duty surface closer with adjustable spring power, and the Norton Rixson 1600 Series aluminum storefront closer with tri-style mounting. All are heavy duty Grade 1 surface closers. What none of them carry is the STA corrosion-resistance construction the 8916 is built around, so for a pool deck, coastal, or chemical plant opening the STA8916 remains the specific answer.
9) I need an ADA compliant closer with adjustable spring sizes 1 through 6 - what are my options besides the STA8916?
The STA8916 is ADA compliant with an adjustable closer size of 1 to 6, letting one unit be tuned down to an ADA-acceptable opening force on an accessible opening and up for a heavy exterior leaf. Peers offering the same size 1-6 adjustable span include the Accentra 2701 Series architectural closer with tri-pack mounting and adjustable spring sizes 1-6, the Norton Rixson 8501A tri-mount closer with adjustable size 1-6 spring, the BEST EHD9000 Series with adjustable spring sizes 1-6, the Imperial USA TC4300 Series Grade 1 heavy duty size 1-6 ADA closer, the LCN 1450 medium duty closer with spring sizes 1-6, and the Arrow DCN325 Grade 1 surface closer with adjustable spring size 1-6. The Calibre CA9901 covers a narrower 2-5 span on a tri-pack arm.
10) Will an Arrow DC314 or DCN314 work in place of a STA8916 on an exterior door?
Those two are built for a different opening. The Arrow DC314 is a Grade 1 surface closer at a light duty level, and the DCN314 is likewise light duty, a Grade 1 surface closer supplied less cover with a regular and parallel arm tri-pack and an adjustable spring size of 1 to 4. The STA8916 is heavy duty with an adjustable size of 1 to 6, so it reaches spring powers the size 1-4 Arrow units do not. Two further points for an exterior leaf: the STA8916 has backcheck standard to protect the door and frame from wind catch, and it is the corrosion-resistant STA construction intended for seashore and severe climate exposure. The DCN314 also comes less cover, where the STA8916 includes a full plastic cover on painted finishes.
11) What finishes does the DORMA STA8916 come in, and do I get a metal cover or a plastic one?
Seven finishes: 689 aluminum, 690 dark bronze, 691 light bronze, 693 black, 695 dark bronze, 696 satin brass, and 630 satin stainless. Cover type follows the finish, not a separate line item. Painted finishes ship with a full plastic cover, and 630 satin stainless ships with a full metal cover. On a corrosive site the 630 stainless with the metal cover is the one that matches the rest of the hardware you'd be specifying there.
12) How is the STA8916 different from a standard DORMA 8900 closer?
Same closer platform, different environment. The STA Series carries the versatility and flexibility of the 8900 or 8600 Series and adds maximum corrosion resistance for severe climates and corrosive exposure. Functionally you get the same adjustable power, adjustable backcheck, and separate sweep and latch speed control. If the opening is interior and dry, a standard closer does the job; the STA is what you buy when salt air, pool chemistry, or plant atmosphere is what's killing the hardware.
13) What else could I use instead of the DORMA STA8916 for a heavy duty Grade 1 surface closer?
For a straight heavy duty Grade 1 surface closer with the same size 1-6 adjustable range, the BEST EHD9000 Series is the closest equivalent, and the Sargent 1431 Powerglide and Falcon SC71A Series are also heavy duty Grade 1 units. The Norton Rixson 1600BC Series is heavy duty Grade 1 and aimed at aluminum storefront. None of those are sold as corrosion resistant the way the STA is, so on a coastal or chemical exposure opening the STA8916 is doing something the others aren't. If the opening is interior and light traffic, a medium duty unit like the Sargent 1331 or Norton Rixson 8501A is more closer than you need to buy.
14) Can I get delayed action on the DORMA STA8916 for a door people push carts through?
Delayed closing is an option on the STA8916, holding the door back from its maximum opening angle down to roughly 70 degrees before the normal sweep takes over. It's the standard answer for laundry rooms, kitchens, and any opening where someone is coming through with a cart or a wheelchair. It's an optional function, so call it out when you order rather than assuming a stock unit has it.
15) Is there a lighter duty Grade 1 surface closer to use instead of a STA8916 on an interior office door?
The STA8916 is a heavy duty closer with an adjustable spring range of size 1 to 6, which is more closer than a low-traffic interior door needs. On lighter interior openings, Grade 1 peers at lower duty levels include the BEST SL6000 Series light duty closer with adjustable spring sizes, the BEST HD7000 Series medium duty closer with adjustable spring power and backcheck control, the Falcon SC81A medium duty cast aluminum closer, the Falcon SC61A light to medium duty cast aluminum closer, the Norton Rixson 160 Series light commercial closer with adjustable spring, and the Sargent 1131 medium duty adjustable surface closer. All six hold Grade 1. The trade is that none of them are built for the corrosive and severe-climate exposure the STA line targets.
16) What is the difference between a DORMA STA8916 and a Sargent 281 or LCN 1460T for a heavy traffic entrance?
All three are heavy duty closers for high traffic entrances. The Sargent 281 Powerglide is a Grade 1 heavy duty closer of cast iron construction; the LCN 1460T is a Grade 1 heavy duty closer supplied in a powder coat finish; the STA8916 is an aluminum-substrate closer with adjustable spring sizes covering 1 to 6 and backcheck standard, non-handed for regular, top jamb and parallel arm applications. The distinguishing point on the STA8916 is corrosion resistance for seashore, pool, offshore, chemical plant and sewage treatment exposure, plus a 630 satin stainless steel option that ships with a full metal cover. Interior lobby and corridor entrances that never see that exposure are squarely in Sargent 281 and LCN 1460T territory.
17) Can I substitute a Grade 2 closer like the Cal-Royal 400 for a STA8916?
Not where the specification calls for Grade 1. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer, while the STA8916 is Grade 1 certified and heavy duty. If a Grade 1 Cal-Royal is what the job needs, the 500S barrier free closer with adjustable back-check, the 700S dual valve sized closer with adjustable tube arm, and the N900PBF barrier free hydraulic closer are all Grade 1. Note as well that grade substitution is only half the question on a corrosive opening, since the STA8916 is the corrosion-resistant option for seashore, pool, offshore and chemical plant service.
18) Which closers besides the STA8916 mount regular, top jamb and parallel arm from the same unit?
The STA8916 is non-handed for regular, top jamb and parallel arm applications, so one unit covers all three mounting positions. Peers built the same way include the Dexter DCH1000 Series Grade 1 surface closer, tri mount for regular, parallel or top jamb with full cover, along with the Dexter DCH4000, DCL2000 and DCM1000 Series, all Grade 1 tri mount; the Norton Rixson 1601P Grade 1 tri-mount closer with 180 degree swing; the Norton Rixson 8501A Grade 1 tri-mount closer; the Accentra 1101BF and 2701 Series with tri-pack mounting; and the Arrow DCN314 and DCN325 Grade 1 surface closers with regular and parallel arm tri-pack. Note the Dexter DCH1000 ships with a full cover; on the STA8916 a full plastic cover is standard on painted finishes and a full metal cover is standard on 630 satin stainless steel.
19) Is the Arrow DCN500DP drop plate a substitute for a STA8916 closer?
No. The Arrow DCN500DP is a parallel drop plate for the DCN500, a mounting bracket that carries a closer body on a parallel arm application, not a closer. The STA8916 is the closer itself, a surface mounted unit with adjustable spring power, backcheck and sweep and latch speed. Two other items that surface in closer searches but do the same non-closing job are the Stanley Security 327 heavy wardrobe pivot for doors 1-3/8 inch or 1-3/4 inch up to 150 pounds and the Stanley Security 341 wardrobe pivot for flush recessed or overlay doors 1-1/8 inch to 1-3/8 inch. Pivots hang a door; a closer controls how it shuts.
20) What is the difference between the STA8916 and a Corbin Russwin DC8200 or DC6200 closer?
The Corbin Russwin DC8200 and DC6200 Series are Grade 1 surface closers supplied with a double lever regular arm for pull side mounting, each listed for a 1-3/4 inch door thickness; the DC3200 is a Grade 1 surface closer with a regular arm, also 1-3/4 inch, and the DC5230 is a Grade 1 surface closer with a slide track arm standard for pull side mounting at the same thickness. Those are pull-side arrangements. The STA8916 is non-handed and covers regular, top jamb and parallel arm applications, and its arm choices are the AR and ARP round form non-hold open arms. It is also the corrosion-resistant option, which the DC Series comparables are not described for.
21) If I am standardizing closers across a facility, which heavy duty lines match the STA8916 across a mixed set of doors?
The STA8916 covers a wide span from one part number: adjustable size 1 to 6, non-handed, and mountable regular, top jamb or parallel arm, in seven finishes from 689 aluminum through 690 and 695 dark bronze, 691 light bronze, 693 black, 696 satin brass and 630 satin stainless. Heavy duty lines that can carry a similar standardization program include the Design Hardware 116 and 416 Series heavy duty closers with a tri-packed non-hold open arm, the Design Hardware 316 Series at medium to heavy duty with the same arm type, the BEST HD8000 and EHD9000 Series, and the Imperial USA TC4300 Series heavy duty size 1-6 ADA closer. Where the facility includes natatorium, coastal or wash-down openings alongside dry interior ones, the STA8916 is the line that spans both, since corrosion resistance is what it is built for.
22) Is a Falcon SC91A an acceptable alternative to a STA8916?
Only on a much lighter opening, and not where the spec is Grade 1. The Falcon SC91A is a light duty cast aluminum surface-mount closer at Grade 3. The STA8916 is Grade 1 and heavy duty with an adjustable size 1 to 6 range. Staying within Falcon, the SC71A heavy-duty surface-mount closer is Grade 1 and the closer match on duty and grade, with the SC81A medium duty and SC61A light to medium duty Grade 1 units sitting between them.
23) What should I use instead of a STA8916 on a residential or light commercial door?
The STA8916 is a commercial, heavy duty Grade 1 closer sized 1 to 6, which is more unit than a light residential opening calls for. Lighter alternatives in the same surface mounted family include the Deltana DC10, DC40, DC50 and DC70 door closers, the LCN 1250 Series light-duty closer in sizes 1-5 with all-weather fluid and ADA compliance, the LCN 1261 with adjustable spring sizes 1-5 and cast iron construction at light to medium duty, and the Norton Rixson 160 Series light commercial closer with adjustable spring. Worth noting on an exposed exterior residential door: the LCN 1250 uses all-weather fluid for temperature swing, while the STA8916 corrosion resistance addresses rust and chemical attack, which are different problems.
24) Which closers compare to the STA8916 for an aluminum storefront entrance?
The STA8916 has an aluminum body, is non-handed for regular, top jamb and parallel arm mounting, and carries backcheck as standard, which matters on a glass storefront leaf that can be caught by wind. The direct storefront peer is the Norton Rixson 1600 Series aluminum storefront door closer with tri-style mounting, heavy duty and Grade 1. The Norton Rixson 1601P Grade 1 tri-mount closer with 180 degree swing is the option where the door needs to swing back flat against a wall. Where the storefront faces a beach, marina or pool deck, the STA8916 is the corrosion-resistant choice, and it can be ordered in 630 satin stainless steel, which comes with a full metal cover.
25) Are the Calibre CA4001 and CA8001P interchangeable with a STA8916?
They cover different ground. The Calibre CA4001 is a Grade 1 adjustable spring tension ADA hydraulic closer, the CA5501 is a Grade 1 standard arm surface mount closer, the CA8001P is a Grade 1 parallel arm closer in size 1 only, and the CA9901 is a Grade 1 tri-pack arm ADA closer in size 2-5. Against those, the STA8916 is Grade 1, ADA compliant, and adjustable across size 1 to 6, so it reaches above the CA8001P size 1 and the CA9901 size 2-5 ceiling for a heavy exterior leaf. The CA8001P is also fixed to a parallel arm application, while the STA8916 is non-handed for regular, top jamb and parallel arm.
26) Is the STA8916 a commercial closer or will it work on an apartment or house door?
Commercial, heavy duty. The STA8916 is built for commercial openings and its spring range runs 1 through 6, so it can be dialed down for a lighter door, but it is priced and built as a corrosion-resistant commercial unit. For a light interior residential-scale door, a light duty closer such as the Arrow DC314 or the LCN 1250 Series is the right class of product.
