LCN 4031-RW/PA-652 – Frequently Asked Questions

1) Will the LCN 4031 closer work on a 4-foot wide exterior door?
Yes. The 4031 with a sized cylinder handles exterior doors up to 4'0" wide and interior doors up to 5'0". If you order the non-sized adjustable cylinder instead, the range drops to 4'0" interior and 3'0" exterior, so on a 4-foot exterior opening you want the sized cylinder. All-weather fluid means the exterior application is covered through temperature swings.
2) Do I have to order the LCN 4031 door closer handed for a left or right swinging door?
No handing to specify. The 4031 is non-handed and mounts three ways on either a left- or right-swinging door: hinge (pull) side, top jamb on the push side, or parallel arm on the push side. One part number covers all three, so a property manager stocking spares only needs one closer on the shelf.
3) Which arm do I order on the LCN 4031 if the door opens against a wall?
Use one of the Cush-n-Stop arms. The 4031 offers CUSH (Cush-n-Stop), SCUSH (spring Cush-n-Stop), HCUSH (hold open Cush-n-Stop) and SHCUSH (spring hold open Cush-n-Stop), all of which build the stop into the arm so the door does not slam into adjacent wall or hardware. If you just want the door to stay open and there is no obstruction, the plain H hold open arm or HWPA hold open with parallel arm bracket does that job.
4) Does the LCN 4031 meet ADA opening force requirements?
Yes, the 4031 is ADA compliant and is certified to ANSI/BHMA A156.4 Grade 1. It is also BAA qualified, which matters on federally funded work. Spring power adjusts across sizes 1 through 4, so you can dial the closing force down to what an accessible opening needs while still getting the door latched.
5) Which arm should I order for a parallel arm installation on the push side of the door?
For push side parallel arm mounting on the 4031, order RWPA (regular arm with parallel arm bracket), HWPA if you also want hold open, or LD/PA for a light duty parallel arm. The Cush-n-Stop arms mount parallel arm as well. A plain REGARM will not do parallel arm work, it needs the bracket, so specify the arm and mounting together on the order.
6) What door closer should I use instead of the LCN 4031 if I need delayed action?
The 4031 has no delay function. The Orca Hardware BHDC1958DA/PA is a delayed action closer with a regular arm and parallel bracket, and the BHDC2011DA/PA is a delayed action closer in the same regular-arm-with-parallel-bracket configuration. Both are listed for 1-3/4 inch doors. The 4031 covers hold open through its H and HCUSH arm options, but hold open and delayed action are different behaviors.
7) What is the closest heavy-duty cast iron equivalent to the LCN 4031 door closer?
The Sargent 281 Powerglide is a cast iron surface door closer built to heavy duty at Grade 1, matching the 4031 on body material and duty level. The 4031 uses an iron cylinder and is rated heavy duty for commercial use. Sargent's 1431 Powerglide is the other heavy-duty Grade 1 surface closer in that family if a cast iron body is not a requirement. Both are surface mounted like the 4031.
8) Which door closer covers spring sizes above 4 when the LCN 4031 tops out at size 4?
The 4031 offers closer sizes 1 through 4. For an opening that needs a higher spring size, the BEST EHD9000 is an extra heavy-duty Grade 1 surface closer with adjustable spring sizes 1-6, and the Accentra 2701 is an architectural closer with adjustable spring sizes 1-6 and tri-pack mounting. The Imperial USA TC4300 is a heavy-duty Grade 1 closer covering sizes 1-6 as well.
9) I need a slide track or concealed-arm closer, not a projecting arm like the LCN 4031 uses. What are my options?
The 4031 uses projecting arm styles including regular, parallel and Cush-n-Stop arms. For a track arm instead, the Corbin Russwin DC5230 is a Grade 1 surface closer with a slide track arm as standard, pull side mounting, for 1-3/4 inch doors. The Dorma 8916-JT is a Grade 1 heavy duty surface closer with a jamb track, frame face mounting on the pull side, adjustable size 1-6.
10) What hold open closer can replace an LCN 4031 with an H arm?
The 4031 offers hold open arms including H, HCUSH, SHCUSH and HWPA. Comparable hold open closers include the Accentra 51 Series, an industrial closer with a tri-packed hold open arm covering sizes 1-6, and the Orca BHDC1958HO/PA, a tri-packed hold open closer with a parallel bracket for 1-3/4 inch doors. The Stanley A45-501HL comes with a long hold open arm standard for top jamb mounting.
11) What is the mounting hole pattern for the LCN 4031 closer?
The 4031 body drills to a 1-23/32" x 6-17/64" pattern. That matters when you are replacing a closer and hoping to reuse existing holes, or when you are checking there is enough flat surface on the door or frame face before you commit. Anything narrower than that footprint needs a drop plate or a different mounting location.
12) What finishes does the LCN 4031 plated closer come in?
Six plated finishes on cover, arm and fasteners: 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, 651 bright chrome and 652 satin chrome. That is the reason to buy the plated version rather than a painted closer, on a lobby or tenant-facing door where the closer is visible and needs to match the lever and hinge finish.
13) Is a cast iron door closer worth it over an aluminum body one?
The 4031 uses a cast iron cylinder with a 1-1/8" piston, full-complement bearing and a forged steel main arm, and it is rated heavy duty for commercial traffic. On a high-traffic entry or a stairwell that gets abused, that mass is what survives. On a light-traffic interior office door an aluminum-body closer is enough, and we carry those too, such as the Falcon SC61A in cast aluminum, rated light to medium duty.
14) I need a heavy duty closer with spring size up to 6, not just 1-4. What else do you have?
The 4031 adjusts spring sizes 1 through 4, which covers most standard commercial leaves. For heavier or wider doors needing size 5 or 6, the BEST EHD9000 Series is extra heavy duty Grade 1 with adjustable sizes 1-6, and the Dormakaba 8916-JT is heavy duty Grade 1 adjustable 1-6 with a jamb track arm. The Imperial USA TC4300 Series is another heavy duty size 1-6 option.
15) Can I standardize a whole building on the LCN 4031?
Across a mixed set of openings, yes for most of them. One non-handed body covers hinge pull side, top jamb push side and parallel arm push side, spring adjusts 1-4, and all-weather fluid means the same closer goes on the exterior entry and the interior corridor doors. The limits to plan around are door width (5'0" interior, 4'0" exterior with the sized cylinder) and no delayed action. Beyond those widths you need a different closer.
16) Is there a lighter-duty commercial door closer than the LCN 4031 for an interior office door?
The 4031 is a heavy duty closer. For lighter interior traffic, the BEST SL6000 is a light duty Grade 1 surface closer with adjustable spring sizes, the Norton Rixson 160 is a light duty Grade 1 light commercial surface closer with an adjustable spring, and the Falcon SC61A is a light to medium duty Grade 1 cast aluminum surface closer. The Arrow DC314 is a light duty Grade 1 surface closer in the DC300 series.
17) Which surface closers besides the LCN 4031 mount three ways on the same body?
The 4031 is non-handed and mounts hinge pull side, top jamb push side, and parallel arm push side. Tri-mount alternatives include the Dexter DCH1000, a Grade 1 surface closer for regular, parallel or top jamb mounting with a full cover, and the Norton Rixson 8501A, a Grade 1 tri-mount closer with adjustable size 1-6 spring. The Design Hardware 116 is a heavy duty closer supplied tri-packed with a non-hold-open arm.
18) Does the Arrow DCN500DP drop plate work as a substitute for an LCN 4031 door closer?
No. The Arrow DCN500DP is a parallel drop plate for the DCN500, a mounting bracket rather than a closer body. The 4031 is a surface mounted door closer with an iron cylinder. If a parallel arm application needs a bracket, the 4031's HWPA and RWPA arm options include the parallel arm mounting bracket.
19) What Grade 2 door closer is available if a project does not require Grade 1?
The Cal-Royal 400 Series is a Grade 2 commercial hydraulic door closer. Within Cal-Royal, the 500S is a Grade 1 barrier free closer with adjustable back-check and the 700S is a Grade 1 dual valve sized closer with an adjustable tube arm. The LCN 4031 is a heavy duty commercial closer that meets ADA reduced opening force requirements.
20) If I want the closer body hidden by a cover, how does the LCN 4031 compare with the less-cover Arrow DCN314?
The 4031 comes with a metal cover over the cylinder. The Arrow DCN314 is a Grade 1 light duty surface closer supplied less cover, with regular and parallel arm tri-pack and adjustable spring size 1-4; the DCN325 is the same less-cover arrangement with spring size 1-6. The Dexter DCH1000 is a Grade 1 tri-mount surface closer supplied with a full cover.
21) What medium duty closer works for a moderate-traffic interior door where an LCN 4031 is more closer than needed?
The Sargent 1131 is a Grade 1 adjustable surface closer for medium-traffic commercial applications, the BEST HD7000 is a medium duty Grade 1 closer with adjustable spring power and backcheck control, and the Dormakaba 7414 is a medium duty Grade 1 closer covering sizes 1-4. The Norton Rixson 1601P is a medium duty Grade 1 tri-mount closer with 180 degree swing.
22) Which closers other than the LCN 4031 are specified for 1-3/4 inch doors?
The Corbin Russwin DC3200, DC6200 and DC8200 are all Grade 1 surface closers listed for 1-3/4 inch doors, the DC3200 with a regular arm and the DC6200 and DC8200 with a double lever regular arm on pull side mounting. The Orca BHDC1958RA/PA is a 1-3/4 inch door closer with a regular arm and parallel bracket, supplied tri-packed non-hold-open.
23) What Grade 1 ADA closers are available besides the LCN 4031 for barrier-free openings?
The LCN 4031 meets ADA reduced opening force requirements. Other Grade 1 ADA closers include the Calibre CA9901 with tri-pack arm covering size 2-5, the Calibre CA4001 with adjustable spring tension, and the Calibre CA8001P, a parallel arm size 1 surface mount closer. The Cal-Royal N900PBF is a barrier free Grade 1 hydraulic surface closer.
24) Is the cover included with the LCN 4031 door closer?
Yes, the 4031 ships with a metal cover, and on the plated versions the cover, arm and fasteners all carry the plated finish. That is a difference worth checking against less-cover closers, for instance the Arrow DCN314 and DCN325 are sold less cover, so on a visible opening you would be buying the cover separately.
25) Are the Stanley Security 327 and 341 alternatives to the LCN 4031?
They are not. The Stanley 327 is a heavy wardrobe pivot for 1-3/8 or 1-3/4 inch doors up to 150 lbs and the Stanley 341 is a wardrobe pivot for flush recessed or overlay doors 1-1/8 to 1-3/8 inch. Pivots carry and swing a door; they provide no hydraulic closing. The 4031 is a surface mounted closer with all-weather fluid that controls the door's return.
