Stanley Security QDC100 R 689 – Frequently Asked Questions

1) Can the Stanley QDC100 closer replace an LCN 4040 without re-drilling the door?
Yes. The QDC100 uses the same footprint, bolt pattern and rounded cover as the LCN 4040, so it goes on the existing prep as a straight off-and-on swap. That is the main reason it gets specified on retrofit work in schools and industrial buildings where the old 4040s are worn out but nobody wants to re-prep a hundred doors.
2) Does the QDC100 door closer body come with the arm, or do I order that separately?
The closer body ships with a full-size rounded plastic cover and no arm. You add the arm as a separate line. The QDC100 family offers 10 arm options across two arm types, a tri-pack arm and an extra duty arm, with varying stop configurations, so pick the arm to suit regular, parallel or top jamb mounting and whether you need a stop in the arm.
3) What door widths will a QDC100 closer handle?
Interior doors from 30 to 48 inches and exterior doors from 32 to 48 inches. Spring power is adjustable across sizes 1 through 6, so one body covers a light interior office door up through a wide exterior entrance, which makes it practical to stock a single closer for a whole building.
4) Do I need to order left hand and right hand QDC100 closers separately?
No. The QDC100 body is non-handed and universal mount, so the same unit works on either swing and mounts pull side or push side. The one exception is the QDC116 arm, which is handed and comes with metal covers. For stocking purposes that means one part number covers both hands on the doors in your building.
5) Is the QDC100 closer fire rated and ADA compliant?
It is UL and cUL listed to UL10c and UL10b for fire door assemblies, certified to ANSI/BHMA A156.4 at Grade 1, and meets ANSI A117.1 for accessibility. Ordering it with the Barrier Free option gets you the reduced opening force setup for accessible openings.
6) What is the closest heavy duty Grade 1 alternative to the Stanley Security QDC100 closer body?
The QDC100 Series is an ANSI/BHMA Grade 1 heavy duty surface mounted closer with cast iron construction and adjustable sizes 1 to 6. The closest heavy duty Grade 1 peers are the BEST EHD9000 Series, the BEST HD8000 Series, the Falcon SC71A, and the Sargent 281 Powerglide, which is also cast iron. All four are catalogued as Grade 1 heavy duty surface closers, so they suit the same institutional and industrial openings. The QDC100 is non-handed and universal mount, which is the detail to confirm against a handed alternative.
7) I am replacing an LCN 4040 - is there a comparable closer besides the QDC100?
The QDC100 Series is built to the same footprint, bolt pattern and rounded cover as the LCN 4040, so it goes on without re-prepping the door. If you want to stay within the LCN line, the LCN 1460T is a heavy duty surface mounted closer and the LCN 1261 is a light to medium duty cast iron closer with adjustable spring sizes 1 to 5. Neither is described as sharing the 4040 bolt pattern, so the QDC100 is the one whose retrofit fit is stated.
8) The QDC100 body ships without arms - which comparable closers come with the arm included?
The QDC100 closer body is ordered without arms, with 10 arm options offered separately across tri-pack and extra duty arm types. If you want a closer that arrives arm-included, the Accentra 1101BF and Accentra 2701 both list a tri-packed non-hold open arm, the Accentra 51 Series lists a tri-packed hold open arm, and the Design Hardware 116, 316 and 416 Series each list a tri-packed non-hold open arm. The Orca BHDC1958 is offered in hold open and non-hold open tri-pack arm versions.
9) I need a barrier free ADA closer - how does the QDC100 compare to other barrier free models?
The QDC100 closer body is offered with a Barrier Free option in 689 aluminum, 690 dark bronze and 696 satin brass, and the series is listed to ANSI A117.1. Comparable barrier free models include the Cal-Royal 500S, a Grade 1 barrier free closer with adjustable back-check, the Cal-Royal N900PBF barrier free Grade 1 hydraulic closer, the Calibre CA9901 tri-pack ADA closer sized 2-5, the Calibre CA4001 adjustable spring tension ADA closer, and the Imperial TC4300 Grade 1 heavy duty ADA closer sized 1-6.
10) What is the difference between the standard and Barrier Free QDC100 options?
Both carry the same cast iron body and Grade 1 rating. The Barrier Free version is the configuration for accessible openings where opening force has to stay within ANSI A117.1 limits, typically interior doors on an accessible route. Order the standard version where you need full closing power on a heavy exterior door and accessibility force limits do not apply.
11) What kinds of doors and frames can a QDC100 closer mount to, and are screws included?
It mounts on wood, aluminum or hollow metal doors and frames. Wood and machine screws come standard, along with sex nuts and self-reaming, self-tapping screws, so you are covered for a solid wood door, a through-bolted application, or drilling into hollow metal without tapping.
12) Do I have to pay extra for delayed action or backcheck on the QDC100?
A back check valve is standard on the QDC100, and delayed action is among the available performance options. Backcheck is what you want on exterior doors exposed to wind so the door cannot be thrown open into the wall; delayed action is for openings where someone needs extra time to get through, like a corridor door in a hospital or a school.
13) Is a cast iron closer like the QDC100 worth it over an aluminum body closer?
For institutional and industrial doors, yes. The QDC100 is rated heavy duty with a cast iron body, cold-forged pinion shaft and forged steel arms, plus staked valves that stop oil leaks if a screw gets backed out too far, and all-weather fluid for exterior doors that see temperature swings. Cast aluminum closers like the Falcon SC81A are medium duty and the SC91A is Grade 3 light duty, which suit lower traffic interior openings. If the door gets abused, go cast iron.
14) The QDC100 is more closer than I need for an interior office door - what is a lighter option?
The QDC100 Series is a heavy duty Grade 1 closer sized 1 to 6 for institutional and industrial traffic. For lighter interior openings, the BEST SL6000 Series is a Grade 1 light duty surface closer, the Norton Rixson 160 Series is a Grade 1 light commercial surface closer with adjustable spring, and the LCN 1250 Series is a light duty surface closer with all-weather fluid and ADA compliance. The Falcon SC91A is a Grade 3 light duty cast aluminum closer if the spec does not call for Grade 1.
15) Which closers besides the QDC100 cover the full adjustable spring range of size 1 through 6?
The QDC100 Series adjusts across closer sizes 1 to 6. Peers with the same stated 1 to 6 range include the BEST EHD9000 Series, the Accentra 51 Series, the Accentra 2701 Series, the Arrow DCN325, the Dorma 8916-JT, the Norton Rixson 8501A, the LCN 1450 and the Imperial USA TC4300. If your range only needs to reach size 4, the Accentra 1101BF and the Arrow DCN314 are sized 1 to 4.
16) The opening needs a slide track or concealed-look arm instead of a surface arm - what should I use instead of the QDC100?
The QDC100 Series mounts pull side or push side with surface arms. If the opening calls for track hardware, 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 heavy duty jamb track closer for frame face, pull side mounting with a flat non-hold open arm. Both are track-arm designs rather than the standard surface arm geometry the QDC100 uses.
17) I need delayed action - does the QDC100 offer it, and what else does?
Delayed action is available as a premium performance option on the Grade 1 QDC100 Series, which also comes with a back check valve as standard. If you are comparing, the Orca BHDC1958DA and the Orca BHDC2011DA are both delayed action closers with a regular arm and parallel bracket, and the Cal-Royal 500S is a Grade 1 closer with adjustable back-check.
18) I need a hold open closer - the QDC100 body is ordered without arms, so what are my options?
Hold open on the QDC100 Series is determined by which of the 10 arm options you pair with the closer body, since the body ships without arms. If you want a closer supplied with a hold open arm out of the box, the Accentra 51 Series lists a tri-packed hold open arm in sizes 1 to 6 and the Orca BHDC1958HO lists a tri-packed hold open arm with a parallel bracket.
19) Our fire doors need a UL10c listed closer - which alternatives to the QDC100 are Grade 1 fire rated candidates?
The QDC100 Series is UL/cUL listed to UL10c and UL10b and certified to ANSI/BHMA A156.4. For a Grade 1 heavy duty equivalent on the same type of labeled opening, look at the BEST HD8000 and EHD9000 Series, the Falcon SC71A, the Sargent 1431 Powerglide and the Sargent 281, all Grade 1 heavy duty surface closers. Confirm the fire label listing on whichever body and arm combination you specify.
20) What finishes does the QDC100 closer cover come in?
Three: 689 aluminum, 690 dark bronze and 696 satin brass, each with the full-size rounded plastic cover. 689 is the usual match for aluminum storefront and hollow metal, 690 for bronze entrances, 696 where existing trim is brass. All three are offered with or without the Barrier Free option.
21) Is the QDC100 overkill for a light interior office door?
Probably. It is a heavy duty commercial closer built for institutional and industrial traffic. For a low-traffic interior door, a medium or light duty unit such as the BEST HD7000 (medium duty, Grade 1), the Norton Rixson 1601P (medium duty, Grade 1), or the light duty BEST SL6000 fits the application better. Keep the QDC100 for exterior entrances, stairwells and doors that get slammed all day.
22) The QDC100 comes with a full round plastic cover - which comparable closers ship less cover or with a metal cover?
The QDC100 closer body is offered with an R full-size rounded plastic cover, and the QDC116 arm configuration uses handed arms with metal covers. Among peers, the Arrow DCN314 and DCN325 are supplied less cover with a regular/parallel tri-pack arm, the Dexter DCH1000 is a Grade 1 tri mount closer with a full cover, and the Design Hardware 316 Series is supplied with a cover.
