Stanley Security DB-3551 689 – Frequently Asked Questions

1) Is the Stanley Security DB-3551 door closer handed, or will one unit work on both left and right hand doors?
Non-handed. One DB-3551 closer body works on either hand of door, so you can stock a single unit for a whole building and decide the swing at install. Mounting is what you choose at the door: it is set up for both pull side and push side mounting.
2) Can the Stanley DB-3551 closer be used on a labeled fire door?
Yes. The DB-3551 is UL/cUL listed and carries UL10c and UL10b, which are the fire door assembly test standards, so it can go on a labeled opening. It also meets ANSI/BHMA A156.4 and ANSI A117.1 for accessibility, which is what an inspector looks for on a barrier free opening.
3) Is the Stanley DB-3551 heavy enough for a high traffic entrance, or is it a light duty closer?
It is a heavy duty, Grade 1 commercial closer, which is the top ANSI/BHMA grade for cycle life and abuse resistance. That is the right class for main entrances, stairwells and corridor doors in schools, healthcare and multi-family, not just interior offices.
4) What is a comparable heavy duty Grade 1 surface door closer to the Stanley Security DB-3551 size 1-4 closer body?
The Stanley Security DB-3551 closer body and cover is a Grade 1, heavy duty surface mounted closer for commercial openings. Close peers on those same two attributes include the BEST HD8000 Series, which is listed Grade 1 heavy duty, the BEST EHD9000 Series extra heavy-duty closer with adjustable spring sizes 1-6, the Falcon SC71A heavy-duty surface-mount closer listed Grade 1, and the Sargent 1431 Powerglide heavy-duty closer with adjustable spring power, also Grade 1. All are surface mounted commercial closers, so the decision comes down to arm and mounting style and finish rather than duty class.
5) I only need a closer for a light interior office door. Is there something lighter than the Stanley DB-3551?
The DB-3551 closer body and cover is rated heavy duty for commercial traffic, which is more closer than a low-traffic interior office door usually needs. Lighter-rated alternatives include the BEST SL6000 Series, listed Grade 1 light duty with adjustable spring sizes, the Arrow DC314 from the DC300 Series, listed Grade 1 light duty, the Norton Rixson 160 Series light commercial closer with adjustable spring, and the LCN 1250 Series light-duty closer in sizes 1-5 with all-weather fluid. The Falcon SC91A is also light duty but is Grade 3 rather than Grade 1, which matters if your spec calls for Grade 1.
6) I need a closer that holds the door open. Does the Stanley DB-3551 do that, or should I pick something else?
The Stanley Security DB-3551 is sold as a closer body and cover in size 1-4, with the arm selected separately, so if hold open is a firm requirement it is simpler to order a closer whose hold open arm is part of the listed configuration. The Accentra 51 Series ships with a tri-packed hold open arm in size 1-6, and the Orca Hardware BHDC1958 hold open model pairs a tri-packed hold open arm with a parallel bracket for 1-3/4 inch doors. If you instead want controlled slow closing rather than a latch-open, the Orca BHDC1958DA and BHDC2011DA are delayed action closers with a regular arm and parallel bracket.
7) The Stanley DB-3551 covers spring size 1-4. What if I need a size 5 or 6 for a wide exterior door?
The DB-3551 body and cover is offered in the size 1-4 configuration. For heavier or wider leaves needing spring power above size 4, closers listed with an adjustable 1-6 range include the BEST EHD9000 Series extra heavy-duty closer, the Dorma 8916-JT Grade 1 heavy duty closer with jamb track arm for pull side frame face mounting, the Norton Rixson 8501A Grade 1 tri-mount closer, the Accentra 2701 Series architectural closer, and the Imperial USA TC4300 Series Grade 1 heavy duty ADA closer. The Arrow DCN325 also spans size 1-6 but is listed light duty.
8) My spec sheet calls for a barrier free ADA closer. Does the Stanley DB-3551 meet that, or is there a better match?
The Stanley Security DB-3551 is listed to ANSI/BHMA A156.4 and ANSI A117.1, the accessibility standard, and is UL/cUL listed including UL10b and UL10c for fire door assemblies. If your submittal names a barrier free closer outright, the Cal-Royal 500S is a Grade 1 barrier free closer with adjustable back-check and the Cal-Royal N900PBF is a Grade 1 barrier free hydraulic surface closer. The Calibre CA4001 and CA8001P are listed as adjustable spring tension ADA closers, and the Imperial USA TC4300 is a Grade 1 heavy duty ADA closer in size 1-6.
9) What mounting screws come with the Stanley DB-3551 closer, and do I need sex nuts for a wood door?
Wood and machine screws come standard, and sex nuts plus self-reaming, self-tapping screws are standard as well. That covers a hollow metal frame, an aluminum application and a wood door where you want to through-bolt rather than rely on wood screws alone.
10) What exactly is the Stanley DB-3551 part, the whole closer or just the body?
The DB-3551 is the closer body together with its cover, in a painted finish. It is the hydraulic unit and the shell that goes over it, ordered by finish, and it is a surface mounted commercial closer rather than a concealed overhead unit.
11) I need a hold open closer, not a standard closer. What should I look at instead?
If the opening needs to stand open, a hold open arm model is the way to go. The Accentra 51 Series is a tri-packed hold open closer, and Orca Hardware's BHDC1958 hold open model comes with a parallel bracket for push side mounting on a 1-3/4 inch door. Just keep in mind that a mechanical hold open is generally not acceptable on a labeled fire door.
12) What other heavy duty Grade 1 surface closers could I use in place of the Stanley DB-3551?
Staying in the same heavy duty Grade 1 class, the BEST HD8000 Series and the Falcon SC71A are direct peers, and the Sargent 1431 Powerglide is another heavy duty Grade 1 surface closer. The LCN 1460T is heavy duty as well, in a powder coat finish. If you are standardizing a facility, pick one series and keep it across the openings so arms, covers and spare parts interchange.
13) Does the Stanley DB-3551 closer meet ADA opening force requirements?
It is listed to ANSI A117.1, the accessible buildings standard that governs door opening force, along with ANSI/BHMA A156.4 for closers. On an accessible interior opening you still need to adjust the spring power down at install and verify the opening force at the door.
14) Can the Stanley DB-3551 be mounted on the push side of the door with a parallel arm?
Yes, the closer is set up for both push side and pull side mounting, so it works regular arm on the pull side or parallel arm on the push side. Push side parallel is the usual choice where the closer would otherwise hang into a corridor or be exposed to abuse.
15) Can I use the Stanley DB-3551 for regular, parallel and top jamb mounting, or do I need a tri-pack closer?
The Stanley Security DB-3551 closer body is non-handed and mounts on either the pull side or the push side. If you want one carton that covers regular arm, parallel arm and top jamb on the job, closers explicitly packed that way include the Dexter DCH1000 Series Grade 1 surface closer with full cover, the Dexter DCH4000 and DCM1000 tri-mount Grade 1 closers, the Arrow DCN314 Grade 1 regular/parallel tri-pack in size 1-4, the Norton Rixson 1600 Series Grade 1 tri-mount closer with 180 degree swing, and the Calibre CA9901 tri-pack arm closer in size 2-5.
16) The Stanley DB-3551 comes with a cover. Which alternatives ship without one?
The DB-3551 is supplied as a closer body and cover, so the metal cover is part of what you receive. Two Arrow closers are catalogued less cover: the DCN314 Grade 1 surface closer in size 1-4 and the DCN325 in size 1-6, both regular/parallel arm tri-packs. If you want a covered unit from another brand, the Dexter DCH1000 Series Grade 1 surface closer is listed with a full cover and the Design Hardware 316 Series heavy duty closer is supplied with cover.
17) Is a Cal-Royal 400 Series an acceptable substitute for the Stanley DB-3551?
Only if the opening does not require Grade 1. The Stanley Security DB-3551 closer body and cover is Grade 1 and heavy duty, while the Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer. If the drawing calls for Grade 1 you would stay with Grade 1 peers such as the Cal-Royal 700S dual valve sized closer with adjustable tube arm, the Corbin Russwin DC8200 Series surface closer, or the Sargent 281 Powerglide cast iron heavy-duty closer.
18) What looks like a substitute for the Stanley DB-3551 but is not?
The Arrow DCN500DP is a parallel drop plate for the DCN500 closer, a mounting accessory rather than a closer, so it will not stand in for the Stanley DB-3551 closer body and cover. Also watch for closers whose arm style is fixed to one mounting: the Corbin Russwin DC5230 is supplied with a slide track arm for pull side mounting and the Dorma 8916-JT uses a jamb track arm for frame face pull side mounting, where the DB-3551 body is non-handed and suits pull side or push side mounting.
19) We are standardizing a medium traffic office building. Is the Stanley DB-3551 overkill, and what is the middle option?
The Stanley Security DB-3551 is a heavy duty Grade 1 closer, which suits high-traffic commercial entries. For interior corridors and offices with moderate use, medium duty Grade 1 closers include the BEST HD7000 Series with adjustable spring power and backcheck control, the Sargent 1131 and 1331, the Falcon SC81A cast aluminum closer, the Dormakaba 7414 in size 1-4, and the Norton Rixson 8501A. Standardizing on one of these across interior openings still keeps you at Grade 1 for the specification.
20) What finishes does the Stanley DB-3551 closer come in?
Two painted finishes: 689 aluminum painted (the matte silver look that blends with aluminum storefront and most hollow metal) and 695 dark bronze painted, which is the one to pick when the building standard is dark bronze frames or anodized entrances.
21) This is going on an interior office door with light use. Is a heavy duty closer overkill?
For a low traffic interior door you can step down and save the difference. The BEST SL6000 Series and the Arrow DC314 are both light duty Grade 1 surface closers, and the Falcon SC81A is a medium duty Grade 1 unit. Keep the heavy duty DB-3551 for entrances, stair doors and anything that takes constant use.
22) The Stanley DB-3551 comes in 689 aluminum and 695 dark bronze. Which comparable closers offer a similar painted look?
The Stanley Security DB-3551 body and cover is offered in 689 aluminum painted and 695 dark bronze painted. Among comparable surface closers, the DORMA 7303 Series standard duty closer and the Dormakaba 7414 are catalogued in painted finish, and the LCN 1460T heavy duty Grade 1 commercial closer is offered in a powder coat finish. The Dormakaba 8616 AF86P FC SNB1 and Dorma 8916-JT are both listed in 689.
