Stanley Security QDC118 R 689 – Frequently Asked Questions

1) Can the QDC118 closer replace an LCN 4040 without re-drilling the door?
Yes. The QDC100 Series shares the same footprint, bolt pattern and rounded cover as the LCN 4040, so it goes on as a direct off-and-on exchange with no re-prep of the door or frame. That is the main reason facilities standardizing on one closer pick this series when they already have 4040s in the building.
2) What door widths will the QDC118 door closer handle?
Spring power is adjustable size 1 through 6, covering 30 to 48 inch interior doors and 32 to 48 inch exterior doors. On an exterior opening narrower than 32 inches you are outside the published range, and on anything over 48 inches you need a different closer.
3) Do I have to order the QDC118 closer handed for a left or right hand door?
No. The QDC118 body and its extra duty arm are non-handed, so one unit stocks for both hands. Handing only becomes a factor on the QDC116 arms, which are handed and use metal covers.
4) Can this closer be mounted parallel arm on the push side, or is it pull side only?
Both. The QDC118 mounts pull side or push side with a universal mount design, which is what lets a maintenance shop carry one part number across mixed openings instead of stocking separate closers per mounting condition.
5) Is the QDC118 closer fire rated and ADA compliant for a hospital or school corridor?
It is UL/cUL listed to UL10c and UL10b, certified to ANSI/BHMA A156.4, and meets ANSI A117.1, which is the accessibility standard behind ADA opening force requirements. There is also a Barrier Free option if you want the closer supplied set up for reduced opening force.
6) What is the closest heavy duty Grade 1 alternative to the Stanley Security QDC118 closer if I need a different brand on the same opening?
The QDC118 is an ANSI/BHMA Grade 1 heavy duty surface closer with adjustable spring sizes 1 to 6. Peers matched on both grade and duty level include the BEST EHD9000 Series extra heavy-duty surface closer with adjustable spring sizes 1-6, the BEST HD8000 Series heavy duty Grade 1 closer, the Falcon SC71A heavy-duty surface-mount closer, the Sargent 1431 Powerglide heavy-duty closer, and the Sargent 281 Powerglide cast iron closer. Confirm arm type and mounting side separately, since the QDC118 is supplied with an extra duty arm with stop and hold open.
7) I do not need heavy duty - what is a lighter closer than the Stanley QDC118 for a low-traffic interior office door?
The QDC118 is rated heavy duty for institutional and industrial openings. For lighter interior traffic, lighter-rated alternatives include the BEST SL6000 Series Grade 1 light duty surface closer, the Arrow DC314 Grade 1 light duty closer, the LCN 1250 light duty closer with sizes 1-5 and all-weather fluid, the Norton Rixson 160 Series light commercial closer, and the Falcon SC91A light duty Grade 3 closer. Note the SC91A is Grade 3 rather than Grade 1, so check your spec before substituting it.
8) The QDC118 arm has a built-in stop - what should I use if the door already has a floor or overhead stop and I do not want stop in the arm?
The QDC118 ships with an extra duty arm with stop and hold open, which is not what you want where a separate stop already limits the swing. Non-hold-open arm alternatives in the same class include the Design Hardware 116 Series heavy duty closer with a tri-packed non-hold open arm, the Design Hardware 416 Series heavy duty closer with the same arm function, the Dorma 8916-JT heavy duty Grade 1 closer with a flat non-hold open arm, and the Accentra 2701 with a tri-packed non-hold open arm in sizes 1-6.
9) What is a barrier free door closer alternative to the Stanley QDC118 if I am standardizing on ADA openings?
The QDC118 is offered in a Barrier Free option alongside the standard build, in 689 aluminum, 690 dark bronze and 696 satin brass, and carries ANSI A117.1. Comparable barrier free and ADA-oriented closers include the Cal-Royal 500S Grade 1 barrier free closer with adjustable back-check, the Cal-Royal N900PBF barrier free Grade 1 hydraulic surface closer, the Calibre CA9901 tri-pack arm ADA closer in sizes 2-5, and the Imperial USA TC4300 Grade 1 heavy duty size 1-6 ADA closer. The TC4300 is the closest on duty level and spring range.
10) What does the stop/hold open arm on the QDC118 actually do?
The extra duty arm on the QDC118 carries a built-in stop with hold open, so the arm itself limits how far the door swings and will hold it open at that point instead of relying on a separate wall or floor stop. Use it where an overswinging door would hit adjacent hardware or a wall, and where staff need the door parked open for carts or deliveries. If you do not want a door that stays open on its own, choose a non-hold-open arm version instead.
11) What is the difference between the None and Barrier Free options on the QDC118?
Two choices on the order: None is the standard closer, Barrier Free is the reduced opening force configuration for accessible openings governed by ANSI A117.1. Both come with the R full-size rounded plastic cover and are offered in all three finishes, 689 aluminum, 690 dark bronze and 696 satin brass.
12) Is a cast iron closer like the QDC118 worth it over an aluminum body closer?
On high-traffic institutional and industrial doors, yes. The QDC100 body is cast iron with a cold-forged pinion shaft and forged steel arms, and it uses staked valves so the adjustment screws cannot be backed out far enough to leak oil. All-weather fluid means the sweep speed holds up on exterior doors in cold weather. For a light-traffic interior office door, a cast aluminum closer such as the Falcon SC81A (medium duty, Grade 1) covers the job with less mass.
13) What other heavy duty Grade 1 surface closers compare to the Stanley QDC118?
Close peers in the same heavy duty, Grade 1, size 1-6 class include the BEST EHD9000 Series and HD8000 Series, the Sargent 1431 Powerglide, the Sargent 281 cast iron closer, and the Falcon SC71A. The LCN 1460T is also heavy duty. What separates the QDC118 is the LCN 4040 footprint and bolt pattern, which makes it the one to pick when you are swapping out existing 4040 closers.
14) Does the QDC118 come with delayed action and backcheck, or are those extras?
A back check valve is standard on the QDC100 Series, and delayed action is offered as a performance option. Backcheck is what protects the closer and the frame when someone throws the door open in a windy entry; delayed action buys extra time for carts, wheelchairs and gurneys before the sweep begins.
15) Which other cast iron door closers compare to the Stanley Security QDC118?
The QDC118 uses a cast iron body with a cold-forged pinion shaft and forged steel arms. Among comparable closers, the Sargent 281 Powerglide is also a cast iron heavy duty surface closer, and the LCN 1261 is built with cast iron construction in a light to medium duty rating. If cast iron is the reason for the specification on a high-traffic institutional opening, the 281 is the closer match on duty level.
16) Is there a slide track or concealed-style closer I should use instead of the Stanley QDC118 on an opening where a projecting arm is not acceptable?
The QDC118 uses a surface-mounted extra duty arm with a stop and hold open, which projects from the door or frame. Where the arm profile is the issue, the Corbin Russwin DC5230 is a Grade 1 surface closer supplied with a slide track arm as standard for pull side mounting, and the Dorma 8916-JT is a Grade 1 heavy duty closer with a jamb track for frame face, pull side mounting. Both are track-style rather than the linked arm arrangement the QDC118 uses.
17) Which alternatives to the Stanley QDC118 also cover the full spring size 1 through 6 range?
The QDC118 is adjustable across closer sizes 1 to 6, which is what lets one closer cover interior doors from 30 inches and exterior doors from 32 inches up to 48 inches wide. Other closers listing the same 1-6 adjustment include the BEST EHD9000 Series, the Accentra 51 Series with a tri-packed hold open arm, the Accentra 2701 with a non-hold open arm, the Arrow DCN325, the Dorma 8916-JT, the Norton Rixson 8501A tri-mount closer, and the Imperial USA TC4300. If you are stocking one closer for a mixed door schedule, these are the peers that match that range.
18) I need a hold open closer but not the Stanley QDC118 extra duty arm - what else holds open?
The QDC118 pairs an extra duty arm with a stop and hold open function. Other hold open options include the Accentra 51 Series industrial closer with a tri-packed hold open arm in sizes 1-6 and the Orca Hardware BHDC1958HO/PA with a tri-packed hold open arm and parallel bracket for 1-3/4 inch doors. Both hold open through the arm rather than combining hold open with a stop in an extra duty arm, so verify how the opening needs to be limited.
19) What is a medium duty step down from the Stanley QDC118 for a moderate-traffic commercial corridor?
Where heavy duty is more closer than the opening needs, Grade 1 medium duty peers include the BEST HD7000 Series with adjustable spring power and backcheck control, the Sargent 1131 for medium-traffic commercial, the Sargent 1331 with a universal aluminum body, the Norton Rixson 1601P tri-mount with 180 degree swing, the Norton Rixson 8501A, the Falcon SC81A cast aluminum closer, the Dormakaba 7303 and the Dormakaba 7414. All are Grade 1 like the QDC118 but rated medium rather than heavy duty.
20) The Arrow DCN325 looks similar to the Stanley QDC118 - what is the difference?
They differ in two ways that matter at install. The Arrow DCN325 is a Grade 1 surface closer supplied less cover with a regular/parallel tri-pack arm and is rated light duty. The QDC118 is heavy duty with cast iron construction and ships with a full-size rounded plastic cover and an extra duty arm with stop and hold open. If the opening needs a covered closer and a stop in the arm, the DCN325 is not a like-for-like swap.
21) Which non-handed closers compare to the Stanley QDC118 for stocking one unit across left and right hand doors?
The QDC118 is non-handed with a universal mount design and can be mounted pull side or push side, which is what makes it practical to stock a single part across a mixed door schedule. Comparable tri-mount or universal peers include the Dexter DCH1000 Grade 1 tri-mount closer that can be regular, parallel or top jamb mounted with a full cover, the Dexter DCH4000 tri-mount closer, the Norton Rixson 1601P tri-mount design, the Norton Rixson 1600 Series with tri-style mounting, and the Sargent 1331 with a universal aluminum body.
22) Which cover and finish do I get on the QDC118 R model, and will it match other closers in the building?
The R configuration ships with a full-size rounded plastic cover in one of three finishes: 689 aluminum, 690 dark bronze, or 696 satin brass. Those are the standard painted closer finishes, so 689 blends with aluminum storefront and 690 with dark bronze entrances. Note the rounded plastic cover is what mirrors the LCN 4040 look; QDC116 arms use metal covers instead.
23) Is the QDC118 a commercial closer or can it be used on a residential door?
It is built and rated for commercial use, heavy duty and Grade 1, aimed at institutional and industrial openings. It will function on a heavy residential door, but the spring range starts at 30 inch interior width and the unit is sized for traffic a house never sees. For light residential work a Deltana DC10 or DC40 closer is the more proportionate choice.
24) Is the Arrow DCN500DP drop plate a substitute for a closer like the Stanley QDC118?
No. The Arrow DCN500DP is a parallel drop plate for the DCN500, a mounting accessory rather than a closer. The QDC118 is a complete Grade 1 heavy duty surface mounted closer with an extra duty arm, stop and hold open, and a full-size rounded plastic cover. A drop plate is ordered in addition to a closer when the frame face does not give enough mounting surface, not in place of one.
