Stanley Security QDC115 M 689 LH – Frequently Asked Questions

1) Can the Stanley QDC115 door closer replace an LCN 4040 without re-prepping the door?
Yes. The QDC100 family, which the QDC115 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 it gets specified on retrofit work in schools and institutional buildings where the existing doors are already prepped for the 4040.
2) What door widths will the QDC115 closer handle?
The adjustable spring covers sizes 1 through 6, which puts it on interior doors from 30 to 48 inches wide and exterior doors from 32 to 48 inches. One unit on the shelf covers a whole building's range, which is why property managers use it to standardize instead of stocking a separate closer per opening size.
3) Is the QDC115 closer handed, and do I need to know the swing before ordering?
The closer body itself is non-handed and universal mount, so it works on either swing. The handing selection matters for the QDC116 arms and metal covers, which are handed. Left and right are both offered across the 689 aluminum, 690 dark bronze and 696 satin brass finishes.
4) Can this closer be mounted on the push side of the door, or only the pull side?
Both. Mounting is pull side or push side, and the unit installs on wood, aluminum, or hollow metal doors and frames. That covers regular arm, parallel arm and top jamb style applications on the same body.
5) Is the Stanley QDC115 fire rated and ADA compliant?
It is UL/cUL listed to UL10c and UL10b for fire door assemblies, certified to ANSI/BHMA A156.4, and meets ANSI A117.1 for accessibility. For barrier-free openings, order the Barrier Free option, which is one of the two option choices offered alongside None.
6) What is the closest heavy duty Grade 1 alternative to the Stanley Security QDC115 door closer?
The QDC115 is a Grade 1, heavy duty surface mounted closer adjustable across sizes 1 to 6. The closest peers on those same terms are the BEST EHD9000 Series, an extra heavy-duty Grade 1 surface closer with adjustable spring sizes 1 to 6, and the BEST HD8000 Series, a heavy duty Grade 1 surface closer. Sargent's 1431 Powerglide and 281 Powerglide are also heavy duty Grade 1 surface closers, the 281 with a cast iron body like the QDC115.
7) The opening needs a slide track or flat arm instead of the QDC115 extra duty arm. What should I use?
The QDC115 is furnished with an extra duty arm. Where the opening calls for track hardware or a flat arm instead, the Corbin Russwin DC5230 is a Grade 1 surface closer with a slide track arm standard for pull side mounting, the Dorma 8916-JT is a Grade 1 heavy duty closer with a jamb track and flat non-hold open arm for frame face pull side mounting in sizes 1 to 6, and the Dormakaba 8616 AF86P is a Grade 1 heavy duty closer with a flat non-hold open tri-pack arm.
8) Is the Cal-Royal 400 Series a substitute for the Stanley QDC115?
Not on a Grade 1 spec. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer, while the QDC115 is Grade 1 and certified to ANSI/BHMA A156.4 with UL/cUL, UL10c and UL10b listing. If you need to stay in the Cal-Royal line at Grade 1, the 500S barrier free closer with adjustable back-check, the 700S dual valve sized closer and the N900PBF barrier free 900 Series closer are the Grade 1 options.
9) What replaces an LCN 4040 if I do not want the Stanley QDC115?
The QDC115 is the direct off-and-on exchange, since the QDC100 body shares the same footprint, bolt pattern and rounded cover as the LCN 4040. Staying within LCN, the 1460T is a heavy duty Grade 1 surface closer in a powder coat finish, and the 1261 is a cast iron closer with adjustable spring sizes 1 to 5 rated light to medium duty. Confirm the existing hole pattern before ordering either LCN, since only the QDC100 is stated to match the 4040 prep.
10) What screws come with the QDC115 and do I need sex nuts for a wood door?
Wood and machine screws come standard, and sex nuts plus self-reaming, self-tapping screws are standard as well. Sex bolts are what you want through a hollow-core or wood door where a screw alone will pull out under repeated closing force.
11) Does the QDC115 have delayed action and backcheck, or are those extra?
A back check valve is standard, and delayed action is available as a premium option. Backcheck is what keeps a wind-caught exterior door from slamming into the wall; delayed action gives someone with a cart or a wheelchair extra time through the opening before the door starts to close.
12) Is a cast iron closer like the QDC115 worth it over an aluminum body closer?
On high-traffic institutional and industrial openings, yes. The QDC100 body is cast iron with a cold-forged pinion shaft and forged steel arms, and the valves are staked so an over-backed adjustment screw will not let oil out. All-weather fluid keeps closing speed consistent through temperature swings on exterior doors. For lighter interior traffic a medium or light duty aluminum body unit is usually enough, for example the Falcon SC81A medium duty cast aluminum closer or the light duty Arrow DC314.
13) How many arm options does the QDC100 series offer and which arm is on the QDC115?
Ten arm options across the series, built on two arm types: a tri-pack arm and an extra duty arm, with varying stop types. The QDC115 is configured with the extra duty arm, which is what you want where the door is likely to be flung open against a stop, such as a loading area or a school corridor.
14) For a medium traffic office building, is there a step down from the QDC115?
Yes. The QDC115 is specified as heavy duty for institutional and industrial openings. For medium traffic, the BEST HD7000 Series is a medium duty Grade 1 closer with adjustable spring power and backcheck control, the Sargent 1131 is a Grade 1 adjustable surface closer for medium-traffic commercial use, the Norton Rixson 1601P is a medium duty Grade 1 tri-mount closer with 180 degree swing, and the Falcon SC81A is a medium duty Grade 1 cast aluminum closer.
15) Which closers offer a hold open arm if the QDC115 extra duty arm does not?
For a hold open function, the Accentra 51 Series is an industrial closer with a tri-packed hold open arm in sizes 1 to 6, and the Orca Hardware BHDC1958 HO/PA is a hold open closer with a tri-packed arm and parallel bracket for 1-3/4 inch doors. If delayed action is what you actually need, the QDC100 family carries delayed action as a premium option alongside standard back check.
16) I need a barrier free ADA closer. How does the QDC115 compare to other ADA options?
The QDC115 is offered with a Barrier Free option in 689 aluminum, 690 dark bronze and 696 satin brass, and the series is certified to ANSI A117.1. Other barrier free choices include the Cal-Royal 500S Grade 1 barrier free closer with adjustable back-check, the Cal-Royal N900PBF barrier free 900 Series closer, the Calibre CA9901 Grade 1 tri-pack arm ADA closer in sizes 2 to 5, and the Imperial USA TC4300, a heavy duty size 1 to 6 ADA closer.
17) Are the Arrow DC300 Series closers equivalent to the Stanley QDC115?
They sit at a different duty level. The Arrow DC314 is a Grade 1 surface mounted closer rated light duty, and the DCN314 and DCN325 are light duty units supplied less cover with a regular/parallel tri-pack arm, the DCN314 adjustable size 1 to 4 and the DCN325 size 1 to 6. The QDC115 is a heavy duty Grade 1 closer with a cast iron body and a full-size metal cover, sized 1 to 6.
18) The QDC115 arms are handed. What non-handed heavy duty closers can I stock instead?
The QDC115 body is non-handed, but the QDC116 arms are handed along with the metal covers, which is why handing is selected at order. If you want a tri-mount closer where one part number covers regular, parallel and top jamb mounting, the Dexter DCH1000 is a Grade 1 surface closer with tri-mount and full cover, the Norton Rixson 8501A is a Grade 1 tri-mount closer adjustable size 1 to 6, and the Design Hardware 416 Series is a heavy duty closer with a tri-packed non-hold open arm.
19) Which closers should I look at for an aluminum storefront door instead of the QDC115?
The QDC115 will mount to aluminum doors and frames as well as wood and hollow metal, on the pull or push side, for door widths of 32 to 48 inches exterior. If you want a unit built specifically for storefront, the Norton Rixson 1600BC Series is a heavy duty Grade 1 aluminum storefront closer with tri-style mounting.
20) What finishes does the Stanley QDC115 come in, and will it match the closers already in my building?
Three finishes: 689 aluminum, 690 dark bronze, and 696 satin brass. Those are the standard powder-coat closer finishes used across most commercial lines, so matching an existing run of closers is usually a matter of picking the same number. The QDC115 configuration carries a full-size rounded cover.
21) Is a drop plate like the Arrow DCN500DP a substitute for a QDC115 closer?
No. The Arrow DCN500DP is a parallel drop plate for the DCN500, a mounting bracket only, with no hydraulic body. The QDC115 is a complete Grade 1 surface mounted closer with cast iron body, extra duty arm and cover, mounting on wood, aluminum or hollow metal doors and frames on the pull or push side.
