    Stanley Security D-3551S 695 – Frequently Asked Questions

    1) Can the Stanley D-3551 closer be mounted on the push side of the door?
    Yes. Three mountings are supported: hinge (pull side), top jamb (push side), and parallel arm (push side). That tri-mount flexibility is why one part number can cover mixed openings in a building, in-swinging and out-swinging.
    2) Do I need to order a handed version of the Stanley D-355 closer?
    No handing to specify. The D-355 Series body is non-handed and works on left or right hand doors, so a property manager can stock one closer for the whole building and set handing at install.
    3) Will this Stanley closer meet ADA door opening force requirements?
    ADA compliant, and certified ANSI/BHMA Grade 1, the highest performance level for surface closers. With adjustable spring sizing from 1 to 4 you can dial the power down on interior barrier-free openings and still meet the closing requirement.
    4) I need a closer that holds the door open instead of the Stanley D-3551 non-hold-open arm. What should I order?
    The Stanley D-3551 ships with a tri-packed non-hold open arm, so it will not stay open on its own. For a hold-open function, the Accentra 51 Series is a tri-packed hold open arm closer in adjustable size 1-6, and the Orca Hardware BHDC1958HO/PA is a hold open closer with a tri-packed hold open arm and a parallel bracket for 1-3/4 inch doors.
    5) My opening needs a slide track or jamb track closer rather than the Stanley D-3551 exposed arm. What are my options?
    The Stanley D-3551 uses a conventional heavy-duty arm mounted hinge/pull side, top jamb, or parallel arm. If the detail calls for track hardware, the Corbin Russwin DC5230 is a Grade 1 surface closer with a slide track arm standard, pull side mounting, for 1-3/4 inch doors, and the Dorma 8916-JT is a Grade 1 heavy duty jamb track closer with frame face mounting, pull side, adjustable size 1-6.
    6) What is the closest equivalent to the Stanley D-3551 surface closer if I need a Grade 1 non-hold-open tri-pack arm in adjustable sizes 1-4?
    The Stanley D-3551 is a Grade 1 surface closer with a tri-packed non-hold open arm and adjustable spring sizes 1 through 4, mountable hinge/pull side, top jamb, or parallel arm. The Accentra 1101BF carries the same tri-packed non-hold open arm function with adjustable spring sizes 1-4, and the Arrow DCN314 is a Grade 1 surface closer with a regular/parallel arm tri-pack in adjustable spring size 1-4, supplied less cover. The Design Hardware 116 Series is another heavy duty closer with a tri-packed non-hold open arm.
    7) Is a Cal-Royal 400 Series closer an equivalent substitute for the Stanley D-3551?
    Not on the certification. The Stanley D-3551 is certified ANSI/BHMA Grade 1 and ADA compliant. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer. If the door schedule specifies Grade 1, the Cal-Royal 500S barrier free closer with adjustable back-check or the 700S dual valve sized closer with adjustable tube arm are the Grade 1 options in that line. The Falcon SC91A is likewise Grade 3 and not a Grade 1 swap.
    8) Will the Stanley D-3551 closer work on an exterior door in cold weather?
    It uses all-weather hydraulic fluid, so closing speed stays consistent through temperature swings on exterior openings. Body construction is R-14 silicon aluminum with a powder coat finish for the exposure.
    9) What mounting hardware comes with the Stanley D-3551 closer?
    The package includes a full plastic cover plus wood and machine screws, sex nuts, and self-tapping screws, so it covers both wood and hollow metal door installs without a separate fastener pack. Drop plates or special brackets for tight top rails are not part of the package.
    10) What is a heavier-duty alternative to the Stanley D-3551 for a high abuse entrance?
    The D-3551 is built for high-use institutional traffic, but if you want a closer rated heavy duty by the manufacturer, the BEST EHD9000 Series is an extra heavy duty Grade 1 closer with sizes 1 to 6, and the Sargent 281 Powerglide is a heavy duty Grade 1 cast iron body. Both give you size 5 and 6 power the D-3551 does not reach.
    11) Is there a lighter-duty alternative to the Stanley D-3551 for a low-traffic interior door?
    The Stanley D-3551 is built for high-use institutional applications with silicon aluminum construction. Where the opening sees lighter service, the BEST SL6000 Series is a Grade 1 surface closer in light duty with adjustable spring sizes, the Norton Rixson 160 Series is a Grade 1 light duty light commercial surface closer with an adjustable spring, and the Arrow DC314 in the DC300 Series is a Grade 1 light duty surface closer. The Falcon SC61A is rated light to medium duty and also Grade 1.
    12) I need a flat arm closer for a narrow top rail instead of the Stanley D-3551. What should I look at?
    The Stanley D-3551 comes with a heavy-duty arm and a full plastic cover. Where a flat arm is required, the Dormakaba 8616 AF86P FC SNB1 689 is a Grade 1 heavy duty closer with a flat arm non-hold open tri-pack, and the Dorma 8916-JT uses a flat non-hold open arm in the 8900 Series, also Grade 1 heavy duty.
    13) Do I need delayed action rather than the standard Stanley D-3551 closing cycle?
    The Stanley D-3551 is a standard non-hold open closer with all-weather fluid. If the opening serves users who need extra time to pass through and the spec calls for delayed action, the Orca Hardware BHDC1958DA/PA and BHDC2011DA/PA are delayed action closers with a regular arm and parallel bracket, tri-packed non-hold open, for 1-3/4 inch doors.
    14) If I am standardizing a whole building on one Grade 1 tri-mount closer, what else covers the same hinge, top jamb and parallel arm mounting as the Stanley D-3551?
    The Stanley D-3551 mounts hinge (pull side), top jamb (push side), or parallel arm (push side). Comparable tri-mount Grade 1 closers include the Dexter DCH1000 Series, which is tri mount regular, parallel or top jamb with a full cover, the Dexter DCM1000 and DCL2000 Series in the same tri mount arrangement, and the Norton Rixson 1601P, a Grade 1 medium duty tri-mount closer with 180 degree swing.
    15) The Stanley D-3551 body is silicon aluminum. What if my spec calls for a cast iron closer?
    The Stanley D-3551 uses R-14 silicon aluminum construction for performance under heavy loads. Where cast iron is specified, the Sargent 281 Powerglide is a cast iron surface closer with heavy-duty construction, Grade 1, and the LCN 1261 in the 1260 Series is a cast iron surface closer with adjustable spring sizes 1-5.
    16) Which heavy duty Grade 1 closers compare with the Stanley D-3551 for a high-traffic institutional opening?
    The Stanley D-3551 is Grade 1 and built for high-use institutional applications. On comparable heavy duty footing, the Falcon SC71A is a Grade 1 heavy-duty surface-mount closer, the BEST HD8000 Series is a heavy duty Grade 1 surface closer, and the Sargent 1431 Powerglide is a Grade 1 heavy-duty surface closer with adjustable spring power. The Design Hardware 416 Series is heavy duty with a tri-packed non-hold open arm like the D-3551.
    17) What medium duty Grade 1 closer sits a step below the Stanley D-3551 for interior office doors?
    The Stanley D-3551 is a Grade 1 closer intended for demanding high-traffic environments. For interior openings with lighter service, the Sargent 1131 is a Grade 1 medium duty adjustable surface closer for medium-traffic commercial applications, the BEST HD7000 Series is Grade 1 medium duty with adjustable spring power and backcheck control, and the Dormakaba 7414 in the 7400 Series is a Grade 1 medium duty closer in size 1-4, matching the D-3551 spring range.
    18) What finishes does the Stanley D-355 closer come in?
    Two painted finishes: 689 aluminum painted and 695 dark bronze painted. 689 is the usual match for aluminum storefront and hollow metal frames; 695 pairs with dark bronze storefront and exterior trim.
    19) Is the Stanley D-3551 suitable for residential use?
    It is classed commercial. Grade 1 certification, all-weather fluid and a silicon aluminum body are aimed at institutional and high traffic openings. For a light residential door a light duty closer like the Falcon SC91A is the closer match.
    20) I ordered an Arrow DCN500DP drop plate thinking it would work with the Stanley D-3551. Is that correct?
    No. The Arrow DCN500DP is a parallel drop plate made for the Arrow DCN500 closer, not a closer itself and not a Stanley component. The Stanley D-3551 ships with its full plastic cover, wood and machine screws, sex nuts, and self-tapping screws for installation, and mounts parallel arm on the push side without that plate.
