    Sure-Loc DC-I50N SP – Frequently Asked Questions

    1) How heavy a door will the Sure-Loc DC-I50N closer handle?
    It is rated for doors up to 180 lbs, with spring power adjustable through sizes 1 to 6. Size 1 suits a light interior door, and the higher sizes cover wide or heavy exterior doors. Because the power is field adjustable, one unit can be tuned on site rather than ordered by size.
    2) Can this closer be mounted on the push side of the door?
    Three mounting positions are covered: hinge (pull side), top jamb (push side), and parallel arm (push side). Which one you use is driven by the opening. Pull side hinge mount is the standard interior application, top jamb works when the frame face gives you room, and parallel arm keeps the closer tucked against the door on the push side where projection into the opening is a problem.
    3) Is the Sure-Loc DC-I50N closer ADA compliant and fire door rated?
    The DC-I50N is ADA compliant and UL rated, and it is certified Grade 1 for commercial use. The adjustable spring range matters for ADA work: sizes at the lower end let you dial opening force down to what an accessible interior opening requires while still closing and latching the door.
    4) Does the Sure-Loc DC-I50N use the LCN 4040 hole pattern, and what LCN closer is the direct alternative?
    Yes. The Sure-Loc DC-I50N is drilled to match the LCN 4040 hole pattern, so it can go back on an opening already prepped for that footprint. If you would rather stay with LCN itself, the LCN 1460T is a heavy duty surface closer offered in a powder coat finish; lighter alternatives in the same family include the LCN 1450, a medium duty closer with spring sizes 1-6, and the LCN 1250, a light duty closer with sizes 1-5.
    5) I need a hold-open arm instead of the regular arm on the Sure-Loc DC-I50N. What should I order?
    The Sure-Loc DC-I50N is supplied with a Regular Arm. If the opening calls for a hold-open function, the Accentra 51 Series is a tri-packed hold open arm closer with adjustable size 1-6, and the Orca Hardware BHDC1958 HO/PA is a tri-packed hold open closer supplied with a parallel bracket for 1-3/4 inch doors.
    6) What is the closest equivalent to the Sure-Loc DC-I50N surface door closer from another brand?
    The Sure-Loc DC-I50N is a heavy duty Grade 1 surface closer with adjustable spring power sizes 1 through 6. The closest heavy duty Grade 1 peers with the same size 1-6 adjustable range are the BEST EHD9000 Series and the Dormakaba 8916-JT, both listed as Heavy Duty Grade 1 with adjustable sizes 1-6. The LCN 1460T is also a Heavy Duty surface closer in a powder coat finish, matching the DC-I50N's powder coat finish type.
    7) Which closers look like substitutes for the Sure-Loc DC-I50N but do not cover the same spring range?
    The Sure-Loc DC-I50N adjusts across spring sizes 1 through 6, so it can be set for a wide interior door or a heavier exterior leaf. Several similar-looking surface closers stop short of that: the Accentra 1101BF adjusts sizes 1-4, the Arrow DCN314 adjusts sizes 1-4, the Dormakaba 7414 is a size 1-4 closer, the LCN 1261 adjusts 1-5, and the Calibre CA9901 covers sizes 2-5. If the opening needs a size 5 or 6 setting, those are not drop-in equals.
    8) Can the Sure-Loc DC-I50N mount parallel arm and top jamb, or do I need a tri-pack closer from another brand?
    The Sure-Loc DC-I50N covers all three surface mountings itself: hinge (pull side), top jamb (push side), and parallel arm (push side). If you prefer a tri-packed unit from another line, the Accentra 2701 Series is a tri-pack non-hold open closer with adjustable sizes 1-6, the Norton Rixson 8501A is a Grade 1 tri-mount closer with an adjustable size 1-6 spring, and the Dexter DCH4000 is a Grade 1 tri-mount surface closer for regular, parallel, or top jamb mounting.
    9) I need a slide track or flat arm closer rather than the Sure-Loc DC-I50N's projecting regular arm. What are the options?
    The Sure-Loc DC-I50N ships with a Regular Arm. Where a low-profile track or flat arm is wanted, the Corbin Russwin DC5230 is a Grade 1 surface closer with a slide track arm as standard for pull side mounting on 1-3/4 inch doors, the Dormakaba 8916-JT is a Grade 1 jamb track closer with a flat non-hold open arm and adjustable size 1-6, and the Dormakaba 8616 is a Grade 1 heavy duty closer with a flat non-hold open tri-pack arm.
    10) Will this door closer work on an exterior door in cold weather?
    Yes. The DC-I50N uses all-weather hydraulic fluid, so closing speed stays consistent through temperature swings rather than slowing to a crawl in winter and slamming in summer. Combined with the 180 lb door rating and heavy duty build, it suits exterior entrances as well as interior traffic doors.
    11) I need to standardize closers across a building. Is this one closer that covers most of my doors?
    For a mixed set of commercial openings, yes. The DC-I50N is Grade 1, heavy duty, adjusts across spring sizes 1 through 6, handles doors to 180 lbs, and mounts hinge, top jamb, or parallel arm. That means one part number and one finish, Silver Powder Coat, across light interior doors and heavy entrances, with the arm position chosen per opening.
    12) The Sure-Loc DC-I50N is more closer than I need for a light interior office door. What is a lighter option?
    The Sure-Loc DC-I50N is rated Heavy Duty for doors up to 180 lbs. For lighter interior traffic, the BEST SL6000 Series is a Light Duty Grade 1 surface closer with adjustable spring sizes, the Norton Rixson 160 Series is a Light Duty Grade 1 light commercial closer, and the Falcon SC91A is a Light Duty closer rated Grade 3. The Arrow DCN314 is a Light Duty Grade 1 tri-pack closer with a narrower adjustable spring range of 1 through 4.
    13) I need delayed action on a barrier-free opening. Does the Sure-Loc DC-I50N do that, or is there another closer for it?
    The Sure-Loc DC-I50N is an ADA compliant Grade 1 closer with a regular arm and all-weather fluid. For an explicit delayed action function, the Orca Hardware BHDC1958 DA/PA and BHDC2011 DA/PA are delayed action closers with a regular arm and parallel bracket for 1-3/4 inch doors. For a barrier free closer with adjustable back-check, the Cal-Royal 500S is a Grade 1 barrier free closer and the Cal-Royal N900PBF is a Grade 1 barrier free hydraulic closer in the 900 Series.
    14) The Sure-Loc DC-I50N has a plastic cover. What heavy duty closer can I use if I want a metal-bodied or cast iron unit?
    The Sure-Loc DC-I50N has a cast aluminum and steel body with a plastic cover. If the spec calls for cast iron, the Sargent 281 Powerglide is a heavy duty Grade 1 cast iron surface closer and the LCN 1261 is a cast iron closer in the 1260 Series. Other heavy duty Grade 1 alternatives include the Sargent 1431 Powerglide, the BEST HD8000 Series, and the Falcon SC71A.
    15) Is there a Grade 2 alternative to the Sure-Loc DC-I50N for a lighter commercial opening?
    The Sure-Loc DC-I50N is a Grade 1 commercial closer. If the specification allows Grade 2, the Cal-Royal 400 Series is a Grade 2 commercial hydraulic door closer. Staying at Grade 1 but stepping down in duty, the BEST HD7000 Series and the Sargent 1131 are both Medium Duty Grade 1 surface closers.
    16) What other heavy duty size 1-6 closers should I look at alongside the Sure-Loc DC-I50N for a high-traffic entrance?
    For a high-traffic opening, the Sure-Loc DC-I50N is Heavy Duty, Grade 1, ADA compliant, with all-weather fluid and doors rated up to 180 lbs. Comparable heavy duty picks include the Imperial USA TC4300, a Grade 1 heavy duty size 1-6 ADA closer; the BEST EHD9000 Series, extra heavy-duty with adjustable spring sizes 1-6; the Design Hardware 416 Series heavy duty tri-packed non-hold open closer; and the Norton Rixson 1600BC, a heavy duty Grade 1 aluminum storefront closer with tri-style mounting.
    17) What is the Sure-Loc DC-I50N closer body made of, and does the cover hold up?
    The body is cast aluminum and steel, with a plastic cover in Silver Powder Coat. The plastic cover is common on this class of closer and keeps the look clean, but in abuse-prone locations like school corridors or loading entries, a metal-cover heavy duty unit such as the BEST EHD9000 or Sargent 281 cast iron closer is worth considering.
