Stanley Security QDC120 R 689 – Frequently Asked Questions

1) Can I swap an LCN 4040 door closer for the Stanley QDC120 without re-prepping the door?
Yes. The QDC100 family, which the QDC120 belongs to, uses 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 new drilling. That is the main reason facilities buyers standardizing on an existing 4040 program pick it up.
2) What door sizes will the Stanley QDC120 closer handle?
Interior doors from 30 to 48 inches wide, and exterior doors from 32 to 48 inches. Spring power is adjustable across sizes 1 through 6, so one closer covers the range from a light interior office door up to a wide exterior entrance. Size the spring to the door width and exposure, not the other way around.
3) What does the extra duty arm with hold open and spring stop actually do on this Stanley closer?
Three jobs in one arm. It holds the door open at a set point so a corridor or loading door can stay propped without a separate wall stop, and the built-in spring stop absorbs the shock when someone throws the door past its intended swing, protecting the closer and the door itself. The arm is forged steel on a cold-forged pinion shaft and a cast iron body, which is what makes it the extra duty option rather than the standard tri-pack arm offered elsewhere in the QDC100 family.
4) Is the Stanley QDC120 ADA compliant for opening force?
The QDC120 is built to ANSI/BHMA A156.4 and ANSI A117.1, which is the accessibility standard governing opening force and closing speed. For an opening that has to meet barrier free requirements, order the Barrier Free option rather than the standard configuration. It is offered in all three finishes.
5) Can I use this Stanley door closer on a fire rated door?
It is UL and cUL listed to UL10c and UL10b, the positive pressure and neutral pressure fire door test standards. One caution on a fire rated opening: a hold open arm is only permitted where the hold open releases on alarm, so if the door must self close under fire conditions, an authority having jurisdiction will usually reject a mechanical hold open. Specify a non-hold-open arm configuration for those doors.
6) What is the closest Grade 1 heavy duty surface closer to the Stanley Security QDC120 if I need another brand?
The QDC120 is a Grade 1 heavy duty surface mounted closer with adjustable spring size 1 to 6. The closest peers on those same points are the Sargent 1431 Powerglide, a Grade 1 heavy duty surface closer with adjustable spring power, the BEST HD8000 Series Grade 1 heavy duty surface closer, and the Falcon SC71A Series Grade 1 heavy-duty surface-mount closer. All three sit in the same Grade 1 heavy duty class, so the deciding factors become arm and stop selection and finish rather than duty rating.
7) I want a cast iron body closer like the QDC120 but from a different manufacturer - what are my options?
The QDC120 uses a cast iron body with a cold-forged pinion shaft and forged steel arms. Two peers are described with cast iron bodies as well: the Sargent 281 Powerglide, a Grade 1 heavy duty cast iron surface closer, and the LCN 1261, a surface-mounted closer with cast iron construction and adjustable spring sizes 1 to 5. Note the LCN 1261 is rated light to medium duty rather than heavy duty, so it covers a narrower traffic range than the QDC120.
8) My opening cannot take a stop in the arm. What should I order instead of the QDC120?
The QDC120 arm includes a spring stop, which is not wanted where a wall stop or floor stop already controls the door swing. Non-hold-open, no-stop alternatives in the same Grade 1 class include the Accentra 2701 with a tri-packed non-hold open arm in sizes 1 to 6, the Design Hardware 416 Series heavy duty closer with a tri-packed non-hold open arm, and the Dorma 8916-JT, a Grade 1 heavy duty closer with a flat non-hold open arm on a jamb track, sizes 1 to 6.
9) Which alternatives to the QDC120 also cover the full size 1 through 6 spring range?
The QDC120 is adjustable through closer sizes 1 to 6. Peers stated in that same range include the BEST EHD9000 Series extra heavy-duty closer with adjustable spring sizes 1 to 6, the Norton Rixson 8501A Grade 1 tri-mount closer with an adjustable size 1 to 6 spring, the Imperial USA TC4300 Grade 1 heavy duty size 1 to 6 ADA closer, and the LCN 1450 with spring sizes 1 to 6. If you are standardizing one part number across both narrow interior doors and wide exterior doors, those are the ones that match the QDC120's adjustment range.
10) I need a barrier free ADA closer - does the QDC120 cover that or should I look at another brand?
The QDC120 is offered in a Barrier Free option alongside the standard build, and is listed to ANSI A117.1. If you are sourcing barrier free from another line, the Cal-Royal 500S is a Grade 1 barrier free closer with adjustable back-check, the Cal-Royal N900PBF is a Grade 1 barrier free surface closer, and the Calibre CA9901 is a Grade 1 tri-pack arm ADA closer in sizes 2 to 5. The QDC120 remains the heavy duty cast iron option among them.
11) We are replacing LCN 4040 closers. Besides the QDC120, is there another heavy duty LCN-family option?
The QDC120 shares the same footprint, bolt pattern and rounded cover as the LCN 4040, so it swaps on without re-prepping the door. If you would rather stay within the LCN line for the heavy duty position, the LCN 1460T is a Grade 1 heavy duty surface-mounted closer in a powder coat finish. Confirm the existing prep against the 1460T before ordering, since the no-re-prep claim is specific to the QDC120's 4040-matched pattern.
12) Can I use a Cal-Royal 400 Series in place of the QDC120 on a school corridor door?
Check the grade before you do. The QDC120 is certified ANSI/BHMA Grade 1 and rated heavy duty for institutional and industrial use. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer. Where a specification or facility standard calls for Grade 1, the 400 Series will not satisfy it; a Grade 1 peer such as the Cal-Royal 700S dual valve sized closer with adjustable tube arm would be the closer match.
13) Are the Deltana DC40 or DC70 closers substitutes for the QDC120 on a commercial fire door?
Treat them as different products. The QDC120 is a commercial Grade 1 closer that is UL/cUL listed to UL10c and UL10b, which is what a fire-rated opening requires. The Deltana DC40 and DC70 are door closers in the DC40 and DC70 series respectively, without a stated grade or fire listing. For a labeled fire door, stay with a Grade 1 listed unit such as the QDC120 or a Grade 1 peer like the BEST HD8000.
14) What kind of doors and frames can the QDC120 mount to, and are the screws included?
Wood, aluminum and hollow metal doors and frames are all covered. Wood and machine screws come standard, and sex nuts plus self-reaming, self-tapping screws are also standard, so you get the through-bolt option for a hollow metal or wood door that needs it and the self-tappers for aluminum without a separate order line.
15) Does the QDC120 have delayed action and backcheck, or do I pay extra for those?
Backcheck is a standard valve on the QDC100 Series, and delayed action is available as a performance option. Backcheck is what stops a wind-caught exterior door slamming into the wall or the frame; delayed action slows the initial close so a cart, a gurney or someone with an armload gets through. On a heavy traffic institutional opening, most specs call for both.
16) I need a hold open closer but not this one. What else is there?
Two straightforward alternatives in the same hold open function: the Accentra 51 Series, which is a tri-packed hold open arm with adjustable size 1-6 like the QDC120, and the Orca Hardware BHDC1958 with a tri-packed hold open arm and parallel bracket for 1-3/4 inch doors. Neither is described as an extra duty arm with a spring stop, so if the reason you want the QDC120 is shock absorption on an abused door, those are not a like-for-like swap.
17) Is a cast iron closer body worth it over cast aluminum for a school or hospital corridor?
For that traffic, yes. Cast iron takes repeated abuse and over-torquing better than a cast aluminum body, and the QDC100 build adds staked valves so an adjustment screw backed out too far will not dump oil, plus all-weather fluid so closing speed holds through temperature swings on an exterior door. Among the alternatives, the LCN 1261 is also cast iron but rated light to medium duty, while the Sargent 281 is a cast iron heavy duty Grade 1 in the same class as this one.
18) Is there a lighter duty alternative to the QDC120 for a low-traffic interior office door?
The QDC120 is built heavy duty for institutional and industrial openings. For a lighter interior application, the Arrow DC314 is a Grade 1 light duty surface closer, the BEST SL6000 Series is a Grade 1 light duty surface closer with adjustable spring sizes, and the LCN 1250 Series is a light duty surface closer in sizes 1 to 5 with all-weather fluid. Each of those trades the QDC120's heavy duty cast iron build for a lighter-traffic package.
19) I need a slide track or concealed-look arm rather than the QDC120's surface arm - what is comparable?
The QDC120 uses an exposed extra duty arm with hold open and spring stop. If the opening calls for a track arm instead, 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 using a jamb track with frame face mounting on the pull side. Both give a low-profile track in place of the QDC120's scissor-style arm.
20) Is the Arrow DCN325 a drop-in substitute for a QDC120?
They are not equivalents. The QDC120 is a heavy duty closer supplied with a full-size rounded plastic cover and an extra duty hold open arm. The Arrow DCN325 is a light duty Grade 1 closer furnished less cover with a regular/parallel tri-pack arm in adjustable sizes 1 to 6. So the DCN325 differs on duty level, does not include a cover, and comes with a non-hold-open tri-pack arm set rather than a hold open arm with spring stop.
21) What is an alternative to the QDC120 for an aluminum storefront entrance?
The QDC120 mounts to wood, aluminum, or hollow metal doors and frames, so it is a candidate on aluminum entrances within its 32 to 48 inch exterior door width range. A peer purpose-built for that opening is the Norton Rixson 1600 Series aluminum storefront closer, a Grade 1 heavy duty unit with tri-style mounting. Both are Grade 1 heavy duty, so the choice comes down to cover style and arm configuration.
22) Is a medium duty closer like the Sargent 1131 or BEST HD7000 enough, or do I need the QDC120?
The QDC120 is a Grade 1 heavy duty closer intended for institutional and industrial traffic, with a cast iron body and all-weather fluid. The Sargent 1131 and the BEST HD7000 are both Grade 1 as well but rated medium duty, as is the Norton Rixson 1601P Grade 1 tri-mount closer. For an office suite or similar moderate-traffic interior those medium duty units carry the same Grade 1 certification; for abusive high-cycle openings the QDC120's heavy duty rating is the differentiator.
23) Which alternatives to the QDC120 give me one part number that mounts regular, parallel, or top jamb?
The QDC120 is non-handed with a universal mount design and can be applied pull side or push side, which is why it stocks well. If you want tri-mount flexibility from another brand, the Dexter DCH1000 is a Grade 1 surface closer with tri mount for regular, parallel or top jamb with a full cover, the Dexter DCM1000 is a Grade 1 tri mount closer, and the Norton Rixson 8501A is a Grade 1 tri-mount closer with a size 1 to 6 spring.
24) If I want delayed action instead of hold open, what compares to the QDC120?
The QDC120 offers delayed action and a back check valve standard as part of the Grade 1 series, though the build with the extra duty arm is configured with hold open and spring stop. For a dedicated delayed action closer from another line, the Orca Hardware BHDC1958DA comes as a delayed action closer with a regular arm and parallel bracket on a tri-packed non-hold open arm, and the Orca BHDC2011DA is the same delayed action arrangement in the BHDC2011 series.
25) Which finishes does the Stanley QDC120 closer come in, and will they match my existing hardware?
Three: 689 aluminum, 690 dark bronze and 696 satin brass. Those are the standard painted closer finishes, so 689 matches most aluminum storefront and 690 matches dark bronze entrances. Each finish is available with or without the Barrier Free option, all with the full-size rounded plastic cover.
26) I ordered an Arrow DCN500DP drop plate thinking it worked with the QDC120 - does it?
No. The Arrow DCN500DP is a parallel drop plate made for the Arrow DCN500 closer, not a closer body and not a QDC120 accessory. The QDC120 is a complete surface mounted closer supplied with wood and machine screws standard plus sex nuts and self-reaming, self-tapping screws. If you need a QDC120 with a hold open arm and spring stop, order the closer itself rather than a drop plate.
