    Sargent 351 O BSP – Frequently Asked Questions

    1) Will the Sargent 351 door closer work on a heavy exterior door, or is it only for interior openings?
    The 351 Powerglide is a heavy duty surface closer with spring power adjustable across sizes 1 through 6, factory set at size 3, so it covers everything from a light interior door up to a wide, heavy exterior leaf once you dial the spring up. The 1-1/2 inch diameter piston is what gives it the control at the top of that range, and the all-weather fluid means you are not re-adjusting it between summer and winter on an exterior opening.
    2) Which arm do I order with a Sargent 351 closer for a deep frame reveal?
    Reveal depth decides the arm on the 351, and it is an ordering choice, not a field fix. For a normal reveal you take the O standard arm or the H hold open arm. For a deeper reveal there are the OZ and HZ arms, and for an extra deep reveal the OZA and HZA. Low ceiling or tight head clearance takes the OLC arm. If you need one arm that suits standard, parallel, or top jamb mounting, order the UO universal standard arm or the UH universal hold open. Mortise foot versions are the O8 and H8. The arms are interchangeable on the closer body, so measure the reveal before you pick.
    3) Can a Sargent 351 Powerglide closer be used on a fire rated door?
    Yes. The 351 is UL 10C listed for the positive pressure fire test and UL/cUL listed for use on fire rated doors. Note that a fire door closer has to close and latch the door, so do not specify a hold open arm on a fire rated opening unless it is tied into a fire alarm release; the plain O, OZ, OZA, OLC, O8 or UO arms are the ones to order there.
    4) Does the Sargent 351 closer meet ADA opening force requirements?
    The 351 is ADA compliant and carries a Grade 1 rating. Because the spring is adjustable over sizes 1 to 6 rather than fixed, you can back the power down to meet the reduced opening force an accessible interior opening calls for, then set the closing speed and latch speed to suit. Adding the DA delayed action option gives a slower sweep so someone using a walker or wheelchair has more time to clear the opening.
    5) How do I mount a Sargent 351 closer if there is no room on the pull side of the door?
    The 351 body is set up for standard (pull side) mounting and top jamb mounting, so when the pull side is unusable you can put it on the frame face above the door with a top jamb application. Top jamb work usually wants the 351A top jamb mounting plate. If your situation actually calls for the closer on the push side with the arm running back to the door, order one of the universal arms, the UO or UH, which cover standard, parallel and top jamb mounting.
    6) What is a straight Grade 1 heavy duty surface closer equivalent to the Sargent 351 Powerglide?
    The Sargent 351 Powerglide is a Grade 1, heavy duty surface mounted closer with adjustable spring power sizes 1 through 6. The closest like-for-like swaps in that same class 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, and the Falcon SC71A Series heavy-duty surface-mount closer, which is also Grade 1 heavy duty. The Dorma 8916-JT is another Grade 1 heavy duty unit with adjustable size 1-6, though it is a jamb track closer with a flat non-hold-open arm rather than a conventional arm closer.
    7) Which surface closer should be used on a light traffic interior door instead of a heavy duty size 1-6 closer?
    On a light interior opening that does not need the full size 1 through 6 range of the Sargent 351, lighter-duty Grade 1 surface closers cover the job: 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 surface closer with adjustable spring, and the LCN 1250 Series is a light duty surface closer with sizes 1-5 and all-weather fluid. The Arrow DC314 in the DC300 Series is also Grade 1 light duty. The Falcon SC91A is light duty but carries a Grade 3 rating, so it will not satisfy a Grade 1 spec.
    8) The Sargent 351 mounts standard or top jamb only. What closer covers a parallel arm opening?
    The Sargent 351 body is non-handed for standard and top jamb mounting, and parallel arm applications on it are handled by the universal arms, the 25-UO standard and 25-UH hold open. If a tri-mount closer is preferred so that regular, parallel, and top jamb are all covered by the same shipped package, the Dexter DCH1000 Series is a Grade 1 tri-mount surface closer with a full cover, the Dexter DCH4000 and DCM1000 Series are Grade 1 tri-mount closers, and the Norton Rixson 8501A is a Grade 1 tri-mount surface closer with adjustable size 1-6 spring. The Norton Rixson 1600 Series is a Grade 1 tri-mount closer with 180 degree swing.
    9) Is hold open available on a Sargent 351, or does it take a different closer?
    Hold open on the Sargent 351 is handled at the arm: the H hold open arm, the H8 mortise foot hold open, the HZ for deep reveals, the HZA for extra deep reveals, and the UH universal hold open arm all convert the same closer body. Closers that arrive as hold open units include the Accentra 51 Series, which is an industrial closer with a tri-packed hold open arm in sizes 1-6, and the Orca Hardware BHDC1958HO/PA, a hold open closer with parallel bracket for 1-3/4 inch doors. The Stanley Security A45-501HL is a long hold open arm for standard and top jamb mounting rather than a closer body.
    10) Which door closers look like a substitute for the Sargent 351 but will not meet a Grade 1 heavy duty spec?
    Several surface closers sit in the same aisle but land in a different class than the Grade 1 heavy duty Sargent 351. The Cal-Royal 400 Series commercial hydraulic closer is Grade 2. The Falcon SC91A is Grade 3 light duty. The Falcon SC81A and the Dormakaba 7303 and 7414 are Grade 1 but medium duty, and the Falcon SC61A is Grade 1 light to medium duty. Two more items in the same family are not closers at all: the Arrow DCN500DP is a parallel drop plate for the DCN500, and the Stanley Security 327 is a heavy wardrobe pivot for 1-3/8 or 1-3/4 inch doors up to 150 pounds.
    11) What is the TB option on a Sargent 351 closer and do I need it?
    TB is through bolting for a 1-3/4 inch door, and it is the option to take on abuse-prone openings and on hollow core or mineral core wood doors where wood screws will eventually pull out. Through bolts sandwich the closer through the door with sex nuts rather than relying on the door face alone. On a solid steel door in a low-traffic corridor the standard fastener pack is normally enough. Order it up front; retrofitting through bolts later means drilling the door.
    12) Is the Sargent 351 the right closer for a high abuse door, like a stairwell or a dock entrance?
    It is a reasonable pick there. The body is die cast aluminum silicon alloy with a heat treated full closed rack and pinion, and built-in pressure relief valves take the shock when someone throws the door open past its stop rather than letting that force wreck the closer or the frame. Pair it with the TB through bolt option on that kind of opening.
    13) What is the Corbin Russwin equivalent to a Sargent 351 surface closer?
    The Sargent 351 is a Grade 1 surface mounted closer. In the Corbin Russwin line the comparable Grade 1 surface closers for 1-3/4 inch doors are the DC3200 with a regular arm and surface mounting, the DC6200 Series and DC8200 Series, both double lever regular arm closers for pull side mounting, and the DC5230 Series, which uses a slide track arm as standard on the pull side rather than a conventional projecting arm.
    14) What closer gives delayed action without ordering it as a Sargent 351 option?
    On the Sargent 351 delayed action is a device option, ordered as DA on the closer itself. If a closer that comes configured for delayed action is wanted instead, 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 Hardware BHDC2011DA/PA is the same delayed action regular arm with parallel bracket arrangement in the BHDC2011 Series, also for 1-3/4 inch doors.
    15) What barrier free ADA door closers compare to the Sargent 351?
    The Sargent 351 is an ADA compliant Grade 1 commercial closer with field adjustable spring power. Other ADA closers in the same Grade 1 class 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 with adjustable spring tension for ADA, and the Imperial USA TC4300 Series, a heavy duty size 1-6 ADA closer. The Calibre CA9901 is a Grade 1 ADA surface mount closer with a tri-pack arm in sizes 2-5.
    16) Which closers come tri-packed so one part number covers regular, parallel, and top jamb?
    The Sargent 351 handles mounting through its interchangeable arm, with the arm type selected at order. Closers supplied tri-packed instead include the Accentra 1101BF with a tri-packed non-hold-open arm in sizes 1-4, the Accentra 2701 architectural closer with tri-pack mounting and adjustable spring sizes 1-6, the Arrow DCN325 Grade 1 surface closer with regular and parallel arm tri-pack in sizes 1-6, the Arrow DCN314 in the same tri-pack arrangement for sizes 1-4, and the Design Hardware 116 and 416 Series heavy duty closers with tri-packed non-hold-open arms. Note that both Arrow DCN units ship less cover, where the Sargent 351 carries a full cover.
    17) What medium duty surface closer works where a heavy duty Sargent 351 is more closer than the opening needs?
    For a moderate traffic opening that does not call for the heavy duty build of the Sargent 351, the Grade 1 medium duty options include the BEST HD7000 Series with adjustable spring power and backcheck control, the Falcon SC81A cast aluminum medium duty closer, the Norton Rixson 1601P tri-mount closer with 180 degree swing, and the Norton Rixson 8501A with adjustable size 1-6 spring. The Design Hardware 316 Series is rated medium to heavy duty with a tri-packed non-hold-open arm and comes with a cover.
    18) What closer suits an aluminum storefront door instead of a Sargent 351?
    The Sargent 351 is a commercial surface closer for standard and top jamb mounting. For an aluminum storefront entrance the Norton Rixson 1600 Series aluminum storefront door closer is built for that opening, Grade 1 heavy duty with tri-style mounting. Where a narrow head or low ceiling condition is the constraint on a Sargent 351 opening, the OLC standard arm for low ceiling addresses it on the 351 itself.
    19) Which closers can be standardized across a facility alongside Sargent 351 openings?
    The Sargent 351 is a Grade 1 heavy duty commercial closer offered in finishes including 10BE dark oxidized satin bronze, EN sprayed aluminum enamel, BSP black suede powder coat, and WSP white suede powder coat. Where a facility wants one Grade 1 family across mixed openings, the Calibre line spans CA4001, CA5501 standard arm, CA8001P parallel arm size 1, and CA9901 tri-pack arm size 2-5, all Grade 1; the Dexter line spans DCH1000, DCH4000, DCL2000, and DCM1000, all Grade 1 tri-mount surface closers. Both give a single-brand ladder from light openings up to the heavier ones a 351 covers.
    20) What finishes does the Sargent 351 door closer come in, and can I match dark bronze storefront?
    Eight finishes: 10BE dark oxidized satin bronze, EB sprayed bronze enamel matching dark satin bronze, ED sprayed bronze enamel matching dark statuary bronze, EP sprayed bronze enamel matching satin bronze, EAB sprayed brass enamel, EN sprayed aluminum enamel, plus BSP black suede and WSP white suede powder coats. For dark bronze storefront, ED or EB is the match depending on which bronze the existing hardware is; 10BE is the plated dark bronze rather than a sprayed enamel and is the one to use where the closer sits at eye level on a public entrance.
    21) Can I standardize a whole building on the Sargent 351, or do I need different closers for different doors?
    One model covers most of a building. The spring adjusts across sizes 1 to 6 so the same closer body suits a light office door and a heavy exterior entrance, and the arm is the piece you vary by opening: standard arm for typical reveals, deep or extra deep reveal arms where the frame is set back, low ceiling arm where head clearance is tight, universal arm where mounting varies. Stocking one body and a few arm types keeps the spare parts shelf short and the maintenance staff on one adjustment procedure.
    22) Are Deltana DC series closers an alternative to the Sargent 351 on a commercial opening?
    The Sargent 351 is a Grade 1 heavy duty commercial closer. The Deltana line covers the DC10, DC40, DC50, and DC70 closers, each its own series. Where a job is specified for Grade 1 heavy duty commercial service, the closers carrying that rating in the comparable field are units such as the BEST HD8000 Series and the Falcon SC71A Series, both Grade 1 heavy duty surface closers.
