Accentra 3521 690 – Frequently Asked Questions

1) Will the Accentra 3521 door closer work on a door where I can't install a floor or wall stop?
That's exactly what the holder/stop arm on the 3521 is built for. The arm carries a stop at its soffit plate that dead stops the door at a set point between 85 and 110 degrees, in 5 degree increments, so the arm itself takes the place of an auxiliary stop. Two cautions worth taking seriously: it's intended for openings where no auxiliary stop can be used and where no more than moderate abuse is expected. On a high-abuse opening (a dock door, a busy school corridor where the door gets thrown open), a separate floor or wall stop is still the better answer, and you'd use a plain closer with it.
2) What is the difference between the Stop Only arm and the Holder Stop Thumbturn arm on the Accentra 3521?
Both arms dead stop the door, but the thumbturn version adds hold open. Stop Only gives you the dead stop at the arm's soffit plate and nothing else, so the door always closes. Holder Stop Thumbturn lets someone set the door to stay open at the stop point by turning the thumbturn, then release it back to normal closing. Pick Stop Only for fire-rated or smoke-partition openings and anywhere the door must never be propped; pick the thumbturn where staff genuinely need the door held open for deliveries, moving, or cleaning.
3) Do I have to order a specific spring size for the Accentra 3521 closer, or does one closer cover different door widths?
One closer covers the range. The 3521 is a multi-sized closer, adjustable through the full power range of sizes 1 through 6, so the same unit handles a light interior door and a heavier exterior one. You set the power on site rather than specifying it on the order. The only things you actually choose when ordering are the arm (Stop Only or Holder Stop Thumbturn) and the finish.
4) Is the Accentra 3521 handed? I need closers for doors swinging both directions in the same building.
Non-handed, so one part number covers left and right hand doors. It also ships tri-style packaged for regular arm, top jamb, and parallel arm mounting, meaning the same box works whether you're mounting on the pull side, the frame face, or the push side. That is the practical reason property managers standardize on it across a building: one stocked item, any opening.
5) What comes in the box with the Accentra 3521 closer, and what else do I need to buy to install it?
The 3521 and 3521T ship with a full molded plastic cover, sex nuts, the parallel arm bracket, and a full-size template. That means for a standard parallel arm install on a hollow metal or wood door you have what you need in the box, including the through-bolt hardware for a door that can't be tapped. Drop plates, brackets for narrow top rails, and any special mounting plate are separate items and are not included.
6) Can the Accentra 3521 keep a door from slamming into the wall when someone shoves it open hard?
Yes, and it does it in two stages. Backcheck starts working at roughly 75 degrees of opening and cushions the door when it's forced open faster than the set opening speed, so the door slows before it reaches the dead stop at 85 to 110 degrees. The stop then holds it there. Backcheck intensity is its own independent valve, separate from sweep and latch, so you can dial the cushioning without changing how the door closes.
7) How far will a door open with the Accentra 3521 installed?
Depends which arm you order. With the holder/stop arm the door dead stops between 85 and 110 degrees, wherever you set it in 5 degree increments. That's the whole point of the arm, and it's a limit, not a suggestion. If you need the full swing, the 3000 Series standard arm applications allow 180 degrees where conditions permit, so you'd order the closer with a standard arm instead of the stop arm. Don't buy the 3521 expecting a 180 degree opening.
8) Is the Accentra 3521 heavy duty enough for a busy exterior entrance?
The 3521 is an aluminum alloy bodied, rack and pinion closer sized 1 through 6, and the holder/stop arm is specified for no more than moderate abuse. On a high traffic exterior entrance where the door gets kicked open, a cast iron or extra heavy duty body is the safer specification. ZenSupply carries the BEST EHD9000 Series as an extra heavy duty adjustable size 1-6 closer, the Sargent 281 Powerglide in cast iron, and the LCN 1460T as heavy duty Grade 1 options for that kind of opening.
9) What is a straight equivalent to the Accentra 3521 multi-sized closer if I need adjustable spring sizes 1 through 6?
The Accentra 3521/3521T adjusts through the full power range of sizes 1 through 6, so any peer that covers the same range will hit the same door weights. The BEST EHD9000 Series is an extra heavy-duty Grade 1 surface closer with adjustable spring sizes 1-6, the Norton Rixson 8501A is a Grade 1 tri-mount surface closer with an adjustable size 1-6 spring, and the Arrow DCN325 is a Grade 1 surface closer with adjustable spring size 1-6 in a regular/parallel arm tri-pack. The Accentra 3521 differs from the Arrow DCN325 in that it ships with a full molded plastic cover, while the DCN325 is supplied less cover. Match the arm separately: the 3521 carries a holder/stop arm with a dead stop between 85 and 110 degrees.
10) I need a closer that also stops the door but the opening is high abuse - what should I use instead of a holder/stop arm closer?
The Accentra 3521 holder/stop arm is intended for openings where an auxiliary door stop cannot be used and no more than moderate abuse is anticipated. For a high-abuse opening, a floor or wall stop plus a heavy-duty closer is the more durable route. Heavy-duty peers include the Sargent 1431 Powerglide, the Falcon SC71A, the LCN 1460T with a powder coat finish, the BEST HD8000 Series Grade 1 closer, and the Design Hardware 416 Series. The Sargent 281 Powerglide is heavy duty with cast iron construction if you want a cast iron body rather than aluminum alloy.
11) My spec calls for an ADA barrier free door closer - which closers state that where the Accentra 3521 does not?
For an opening written to a barrier free or ADA line item, peers that state it directly are the Cal-Royal 500S Grade 1 barrier free closer with adjustable back-check, the Cal-Royal N900PBF 900 Series barrier free Grade 1 hydraulic surface closer, the LCN 1250 Series light duty closer with sizes 1-5 and ADA compliance, the Imperial USA TC4300 Series Grade 1 heavy duty size 1-6 ADA closer, the Calibre CA9901 tri-pack arm size 2-5 ADA closer, the Calibre CA4001 adjustable spring tension ADA hydraulic closer, and the Calibre CA8001P parallel arm size 1 ADA closer. The Imperial TC4300 matches the Accentra 3521 on adjustable size range 1 through 6.
12) I need a delayed action closer for an accessible entrance - what takes the place of the Accentra 3521?
The Accentra 3521 offers independent latch, sweep and backcheck adjustment but the sweep control runs from full open down to about 10 degrees, which is not the same as a delayed action hold at the top of the swing. For delayed action, 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 BHDC2011DA/PA is a delayed action closer with the same regular arm and parallel bracket arrangement for 1-3/4 inch doors. Both carry a tri-packed non-hold-open arm, so pair them with a separate stop if the opening still needs one.
13) The door closes fast and bangs the latch. What can I adjust on the Accentra 3521?
Three independent valves handle it on the 3521. Sweep controls speed from full open down to about 10 degrees from closed. Latch controls the last stretch, from roughly 10 degrees to fully shut, which is the range where a banging door is actually happening, so latch speed is the valve to slow. Backcheck is separate again and affects only the opening cycle. Because the valves are independent, slowing the latch does not change your sweep timing or the door's ADA-style opening feel.
14) What finishes does the Accentra 3521 closer come in, and will it match the other closers in my building?
Four painted finishes: 689 aluminum, 690 dark bronze, 691 light bronze, and 696 satin brass. Both arm types are offered in all four. Those are standard BHMA finish numbers, so 689 and 690 will sit alongside the aluminum and dark bronze closers already hung in most commercial buildings without looking off. If your existing openings are dark bronze storefront, 690 is the match.
15) I need a Grade 1 certified surface closer for a spec job. Does the Accentra 3521 fit, or should I look at something else?
If the drawing calls out a Grade 1 closer by certification, order a closer whose Grade 1 rating is on record. ZenSupply stocks several adjustable size 1-6 Grade 1 surface closers: the BEST EHD9000 Series, the Norton Rixson 8501A tri-mount, the Dormakaba 8916-JT jamb track closer, and the Arrow DCN325 tri-pack. Any of those covers the same size range as the 3521. If what the spec actually needs is an integral stop rather than a grade line item, the 3521's holder/stop arm is the feature to keep.
16) Can I mount the Accentra 3521 on the push side of the door?
Yes. The closer is tri-style packaged for regular arm, top jamb, and parallel arm mounting, and the parallel arm bracket is in the box, so a push side parallel install needs no extra bracket purchase. Parallel arm is the usual choice when you want the closer body out of the corridor, on the door face, with the arm running along the frame. A full-size template is included for laying out whichever of the three mountings you use.
17) Can I install the Accentra 3521 on a door that can't be tapped for screws?
Sex nuts are included with the 3521, so the closer can be through-bolted rather than relying on tapped holes. That's what you want on a hollow metal door with thin face sheets, or a wood door that won't hold a machine screw under closer load. Follow the included full-size template for the hole layout on the door and frame before drilling.
18) What is a simpler surface closer for a light interior office door that does not need a stop arm?
When the door already has a wall or floor stop, the holder/stop arm on the Accentra 3521 is not doing work, and a plain non-hold-open closer covers it. The Arrow DC314 is a Grade 1 light duty surface closer, the BEST SL6000 Series is a Grade 1 light duty surface closer with adjustable spring sizes, the Norton Rixson 160 Series is a Grade 1 light duty light commercial closer, and the LCN 1250 Series is a light duty closer with sizes 1-5, all-weather fluid and ADA compliance. The Falcon SC91A is light duty at Grade 3. The Accentra 3521 covers the wider size 1 through 6 range, so if the door is heavy or exposed to wind, stay with the wider range.
19) Which door closers give me the same tri-style mounting flexibility as the Accentra 3521?
The Accentra 3521/3521T is tri-style packed for regular arm, top jamb and parallel arm mounting, and it is non-handed, so one part number covers either hand and any of the three mounting positions. Peers with the same tri-mount packaging include the Norton Rixson 1601P Grade 1 tri-mount closer with 180 degree swing, the Dexter DCH1000 Series Grade 1 tri-mount closer with full cover, the Dexter DCM1000 and DCL2000 Series Grade 1 tri-mount closers, the Arrow DCN314 regular/parallel arm tri-pack, and the Rixson 1600 Series aluminum storefront closer with tri-style mounting. The Dormakaba 8616 AF86P is a Grade 1 tri-pack with a flat non-hold-open arm.
20) Which closers besides the Accentra 3521 have adjustable backcheck for a door that gets thrown open?
The Accentra 3521 has separate and independent latch, sweep and backcheck intensity valves, with backcheck beginning at approximately 75 degrees of opening to cushion the door before the stop engages. Among peers, the BEST HD7000 Series is a Grade 1 medium duty surface closer with adjustable spring power and backcheck control, and the Cal-Royal 500S is a Grade 1 barrier free closer with adjustable back-check. The Cal-Royal 700S is a Grade 1 dual valve sized closer with an adjustable tube arm. On the Accentra the backcheck works together with the holder/stop arm, so the door is slowed before it reaches the dead stop.
21) What looks like a substitute for the Accentra 3521 but will not work on my door?
Several nearby part numbers are not surface closers at all. The Arrow DCN500DP is a parallel drop plate for the DCN500, a mounting accessory rather than a closer. The Stanley Security 327 is a heavy wardrobe pivot for doors 1-3/8 inch or 1-3/4 inch up to 150 pounds, the Stanley 341 is a wardrobe pivot for flush recessed or overlay doors 1-1/8 inch to 1-3/8 inch, and the Stanley 57-0100 is a box of 100 steel machine screws for architectural hinges. None of those provide the rack and pinion closing, adjustable size 1 through 6 power, or holder/stop function of the Accentra 3521/3521T.
22) Are there closers with a slide track or double lever arm instead of the Accentra 3521 stop arm for a narrow or aesthetic opening?
Where a projecting stop arm will not suit the opening, the Corbin Russwin DC5230 Series is a Grade 1 surface closer with a slide track arm standard for pull side mounting on 1-3/4 inch doors. The Corbin Russwin DC6200 and DC8200 Series are Grade 1 surface closers with a double lever regular arm for pull side mounting, also on 1-3/4 inch doors, and the DC3200 is a Grade 1 closer with a regular arm. The Dormakaba 8916-JT is a Grade 1 heavy duty jamb track closer for frame face pull side mounting, adjustable size 1-6. Note that the slide track and jamb track options are described for pull side mounting, while the Accentra 3521 can be mounted regular arm, top jamb or parallel arm.
23) My facility standardizes on Grade 1 door closers - which peers to the Accentra 3521 carry a stated Grade 1 rating?
For a facility standard written to ANSI/BHMA Grade 1, the peers that state Grade 1 span every duty level. Heavy duty Grade 1 includes the BEST EHD9000 and HD8000 Series, the Falcon SC71A, the Sargent 1431 and Sargent 281, and the Rixson 1600 Series. Medium duty Grade 1 includes the BEST HD7000, the Falcon SC81A, the Sargent 1131 and 1331, the Norton Rixson 1601P and 8501A, and the Dormakaba 7303 and 7414. Light duty Grade 1 includes the Arrow DC314, the BEST SL6000 and the Norton Rixson 160. The Falcon SC61A is Grade 1 at light to medium duty. Grade 2 is covered by the Cal-Royal 400 Series hydraulic closer.
24) The Accentra 3521 is aluminum alloy - what are the cast iron and cast aluminum alternatives?
The Accentra 3521/3521T uses an aluminum alloy housing with rack and pinion operation. If the specification calls out a cast body, the LCN 1261 is a surface closer with adjustable spring sizes 1-5 and cast iron construction, and the Sargent 281 Powerglide is a cast iron surface closer with heavy-duty construction. For cast aluminum, the Falcon SC61A, SC81A and SC91A are cast aluminum surface closers, and the LCN 1450 is a medium duty closer with cast aluminum construction and spring sizes 1-6, which matches the Accentra size range.
25) Does the Accentra 3521 come with a cover, or is that separate?
Both the 3521 and 3521T ship with a full molded plastic cover, so the closer body is concealed once installed. That matters if you're comparing against less-cover models: the Arrow DCN314 and DCN325 are sold less cover, meaning the closer body stays exposed unless you buy the cover separately. On a lobby or tenant-facing door, a covered closer is usually what the owner expects.
26) What is a mid-range alternative when the Accentra 3521 size 1-6 range is more than a moderate-traffic door needs?
On a moderate-traffic interior opening the full size 1 through 6 range of the Accentra 3521 may be more adjustment than the door calls for. The Sargent 1131 is a Grade 1 adjustable surface closer described for medium-traffic commercial applications, the Sargent 1331 is a Grade 1 medium duty closer with a universal aluminum body, the Dormakaba 7303 Series is a Grade 1 standard duty surface closer in a painted finish, and the Dormakaba 7414 is a Grade 1 medium duty closer with size 1-4. The Arrow DCN314 covers adjustable spring size 1 - 4 in a regular/parallel arm tri-pack.
