    Sure-Loc DC-C71N SP – Frequently Asked Questions

    1) Will the Sure-Loc DC-7C1N door closer drop into the holes left by a Norton 8300 closer?
    Yes. The Sure-Loc DC-7C1N surface closer is built to the Norton 8300 hole pattern, so on a replacement it reuses the existing prep instead of requiring new drilling. That makes it a straight swap where an 8300 is coming off the door.
    2) How heavy a door can this Sure-Loc surface closer handle?
    Up to 180 lbs. The spring power is field adjustable across sizes 1 through 6, so one closer covers everything from a light interior door up to a heavy exterior one without swapping bodies. You set the size to suit the door width, weight and any wind exposure at install.
    3) Can this closer be mounted on the push side of the door?
    Three mountings are supported: hinge (pull side), top jamb (push side) and parallel arm (push side). So yes, push side works either as top jamb on the frame face or as a parallel arm tucked under the head. Pull side hinge mounting is the other option when the door swings away from the corridor.
    4) Is this door closer ADA compliant for a barrier-free opening?
    The DC-7C1N is ADA compliant and Grade 1, and because the spring power adjusts down through size 1 you can dial the opening force to meet accessible-route requirements on an interior door while still getting positive latching.
    5) I only need a light interior office door closed, not a 180 lb exterior door. What is a lighter option than the Sure-Loc DC-7C1N?
    The Sure-Loc DC-7C1N is rated for doors up to 180 lbs with spring sizes 1 through 6, which is more range than a light interior office door needs. Lighter-duty alternatives include the Arrow DCN314 Grade 1 surface closer with adjustable spring size 1 to 4, the BEST SL6000 Series Grade 1 light duty closer, the Norton Rixson 160 Series light commercial closer, and the LCN 1250 Series light-duty closer with sizes 1 through 5 and all-weather fluid. The Falcon SC91A is a light duty closer rated Grade 3 rather than Grade 1.
    6) What is the closest equivalent to the Sure-Loc DC-7C1N adjustable size 1-6 Grade 1 surface closer from another brand?
    The Sure-Loc DC-7C1N is a Grade 1 surface closer with adjustable spring power sizes 1 through 6, mounting regular arm on the pull side, top jamb, or parallel arm on the push side. Closely matched alternatives with the same adjustable 1-6 range and Grade 1 rating include the Norton Rixson 8501A tri-mount closer, the BEST EHD9000 Series extra heavy-duty closer, and the Arrow DCN325 Grade 1 surface closer with regular/parallel tri-pack arm. The Imperial USA TC4300 Series is also a Grade 1 size 1-6 ADA closer in a heavy duty build.
    7) What should I use instead of the Sure-Loc DC-7C1N on a narrow top rail or aluminum storefront door?
    The Sure-Loc DC-7C1N is a surface closer mounting regular arm pull side, top jamb, or parallel arm push side on a conventional door and frame. For aluminum storefront openings, the Norton Rixson 1600BC Series is a heavy duty Grade 1 aluminum storefront closer with tri-style mounting. Where a slide track rather than a projecting arm is wanted, the Corbin Russwin DC5230 is a Grade 1 surface closer with a slide track arm standard for pull side mounting, and the Dorma 8916-JT is a Grade 1 jamb track closer for frame face pull side mounting with adjustable size 1-6.
    8) Is a Cal-Royal 400 Series closer the same thing as the Sure-Loc DC-7C1N?
    No. The Sure-Loc DC-7C1N is a Grade 1 closer, while the Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer. If you need to stay at Grade 1 within the Cal-Royal line, 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 the Grade 1 options.
    9) The Sure-Loc DC-7C1N matches the Norton 8300 hole pattern. Are there other closers that fit an existing prep like that?
    The Sure-Loc DC-7C1N uses a mounting hole pattern that matches the Norton 8300 pattern, which is what makes it a retrofit candidate on an existing prep. Other Grade 1 tri-mount closers to consider for a retrofit are the Norton Rixson 8501A of the 8000 Series, adjustable size 1-6, the Norton Rixson 1601P 1600 Series Grade 1 tri-mount closer with 180 degree swing, and the Dexter DCH4000 Series Grade 1 tri mount closer for regular, parallel, or top jamb mounting. Confirm the existing hole centers against the replacement cut sheet before ordering.
    10) Will this closer hold the door open, or does it always close?
    It ships with a regular arm, non-hold-open, so the door closes every time. If you need the leaf to stay parked, look at a hold-open version instead: the Accentra 51 Series carries a tri-packed hold open arm, and Orca Hardware's BHDC1958 is offered as a hold open with parallel bracket.
    11) Is this door closer OK for an exterior door in cold weather?
    It uses all-weather hydraulic fluid, so the closing speed stays reasonably consistent through temperature swings rather than turning sluggish in winter. Body is cast aluminum and steel and the finish is a powder coat, both suited to an exterior opening.
    12) Does the closer come with mounting screws, or do I need to order them separately?
    Mounting hardware is included, and the closer comes with a plastic cover over the body. What is not included is a drop plate or bracket for tight top rails and blade stops, so check the head condition on your opening before you get to site.
    13) Is this a residential or a commercial door closer?
    Commercial. It is a Grade 1, UL rated surface closer intended for commercial openings, which is the grade most institutional and multi-family specs call for on a fire-rated or high-traffic door.
    14) Which other size 1-6 adjustable closers compare to this Sure-Loc?
    Several Grade 1 tri-mount closers cover the same 1-6 adjustable range: the Norton Rixson 8501A, the Accentra 2701 Series, the Arrow DCN325 (supplied less cover), the Dorma 8916-JT, and the Imperial USA TC4300 Series. If you only need sizes 1-4, the Arrow DCN314 and Dormakaba 7414 narrow the range.
    15) Should I use a parallel arm or top jamb mount on a door that swings out into a corridor?
    Both are push-side options on this closer. Parallel arm keeps the closer and arm tucked back under the door head, out of the corridor and less exposed to abuse, which is the usual choice on out-swinging exterior and stairwell doors. Top jamb mounts the body on the frame face and is what you use when the top rail is too narrow to carry the closer, such as on a narrow-stile aluminum door.
    16) The Sure-Loc DC-7C1N has a plastic cover. What closers offer a metal or no-cover alternative?
    The Sure-Loc DC-7C1N ships with a plastic cover over a cast aluminum and steel body. If the opening calls for something else, the Arrow DCN325 and DCN314 are supplied less cover, and the Dexter DCH1000 Series Grade 1 tri-mount closer is specified with a full cover. The Design Hardware 316 Series is a medium to heavy duty closer supplied with a cover.
    17) I am standardizing a building on one closer. Which alternatives to the Sure-Loc DC-7C1N are heavy duty for high-traffic entrances?
    The Sure-Loc DC-7C1N is a Grade 1 commercial closer with all-weather fluid and adjustable sizes 1-6, suited to doors up to 180 lbs. For the heaviest traffic doors in a standardization program, heavy duty Grade 1 options include the BEST HD8000 Series, the Falcon SC71A Series, the Sargent 1431 Powerglide, the Sargent 281 Powerglide cast iron closer, and the Dormakaba 8600 Series 8616 with a flat arm tri-pack. The LCN 1460T is a heavy duty closer in a powder coat finish.
    18) Is there a medium duty Grade 1 alternative to the Sure-Loc DC-7C1N for interior corridor doors?
    The Sure-Loc DC-7C1N covers spring sizes 1 through 6 for doors up to 180 lbs. On interior corridor doors a medium duty Grade 1 closer is often the better fit: the BEST HD7000 Series with adjustable spring power and backcheck control, the Sargent 1131 for medium-traffic commercial applications, the Sargent 1331 with a universal aluminum body, the Falcon SC81A cast aluminum closer, the Dormakaba 7303 Series standard duty closer, and the LCN 1450 with cast aluminum construction and spring sizes 1 through 6.
    19) My spec sheet calls out a 1-3/4 inch door. Which closers list that door thickness alongside the Sure-Loc DC-7C1N?
    Peers that publish a 1-3/4 inch door thickness include the Corbin Russwin DC3200 Grade 1 regular arm surface closer, the DC6200 and DC8200 Series Grade 1 double lever regular arm closers for pull side mounting, and the Orca Hardware BHDC1958 and BHDC2011 Series closers with parallel brackets. The Sure-Loc DC-7C1N itself is a surface mounted closer that installs to the door face or frame face rather than through the door, in regular arm pull side, top jamb, or parallel arm push side configurations.
    20) What is the difference between the Sure-Loc DC-7C1N and a parallel-arm-only closer like the Calibre CA8001P?
    The Sure-Loc DC-7C1N is supplied with a regular arm and mounts three ways: hinge mount on the pull side, top jamb on the push side, or parallel arm on the push side. The Calibre CA8001P is a Grade 1 parallel arm size 1 ADA surface mount closer, fixed to that single arm style and size, while the Calibre CA5501 is a Grade 1 standard arm surface mount closer. Choose by whether the opening needs the arm out of the traffic path on the push side or a projecting arm on the pull side.
    21) What finish does the Sure-Loc adjustable closer come in?
    One finish only: SP Silver Powder Coat. It is matched to the rest of the Sure-Loc Commercial Hardware line, so if you are already running Sure-Loc trim on a building the closers won't look off. If you need a bronze or dark painted closer to match existing hardware, this isn't the one.
    22) What are the non-hold-open tri-pack alternatives to the Sure-Loc DC-7C1N?
    The Sure-Loc DC-7C1N ships with a regular arm and supports regular, top jamb, and parallel arm mounting. Comparable tri-packed non-hold open closers include the Accentra 2701 Series architectural closer with adjustable spring sizes 1-6, the Accentra 1101BF industrial closer with adjustable spring sizes 1-4, the Design Hardware 116 and 416 Series heavy duty closers, and the Orca BHDC1958RA/PA with a regular arm and parallel bracket.
