LCN 4031-RW/PA-689 – Frequently Asked Questions

1) Will an LCN 4031 closer work on an exterior door, and how wide a door can it handle?
The LCN 4031 is sized for exterior doors up to 4'0" wide and interior doors up to 5'0". Spring power adjusts through sizes 1 to 4, so one closer covers a range of openings rather than being locked to a single door width. The all-weather fluid is the part that matters outdoors: sweep and latch speed hold steady through temperature swings instead of running fast in summer and dragging in winter. Wider than 4'0" on an exterior opening and you have outgrown a size 1-4 closer.
2) Do I have to order the LCN 4031 in a left hand or right hand version?
Handing is not something you specify. The 4031 is a non-handed closer, so the same unit goes on a left or right swinging door, and it ships with a peel-n-stick template for layout. What you do have to decide is the arm and which side of the door it mounts on, since those are the two things that change from opening to opening.
3) Can the LCN 4031 be mounted on the push side of the door, or only the pull side?
Three mounting positions are covered: hinge mount on the pull side, top jamb mount on the push side, and parallel arm mount on the push side. Pull side is the usual choice when the closer body can live on the door face out of the traffic; top jamb puts the body on the frame when the door has a narrow top rail or a glass face; parallel arm tucks the arm flat against the frame on the push side where you want the least projection into the opening. For push side parallel arm work, the RWPA and HWPA arms come with the parallel arm mounting bracket, and the Cush-n-Stop arms are parallel arm applications as well.
4) Which LCN 4031 arm do I order if I want the door to stay open?
Four of the arm choices hold the door open: H (hold open arm), HWPA (hold open with the parallel arm bracket), HCUSH (hold open Cush-n-Stop) and SHCUSH (spring hold open Cush-n-Stop). The rest close every time, including REGARM, RWPA, LONG, EDA, LD, LD/PA, CUSH and SCUSH. Worth knowing before you pick: a hold open arm on a fire rated opening is generally not permitted, so on rated doors specify one of the non hold open arms.
5) Will the LCN 4031 stop the door from swinging into the wall behind it?
Only with the right arm. Order CUSH, SCUSH, HCUSH or SHCUSH and you get a Cush-n-Stop arm, which carries the stop in the parallel arm soffit shoe so the arm itself limits the swing, no separate overhead stop needed. The plain REGARM, RWPA, LONG, LD and LD/PA arms have no stop in them, so a door with nothing behind it to catch it will need a wall or floor stop. EDA is the extra duty arm for openings that take abuse.
6) Does the LCN 4031 meet ADA opening force for a school or hospital corridor door?
Yes. The 4031 is ADA compliant and meets ADA reduced opening force requirements, and it is tested to ANSI/BHMA A156.4 Grade 1 for heavy duty commercial use. Because spring power adjusts across sizes 1 through 4, you can dial the closer down to hit the 5 lbf interior push force an inspector checks for and still have enough power left to latch the door. That adjustability is what lets one part number serve a corridor door and a heavier entry in the same building.
7) I am replacing an old closer. Will the LCN 4031 line up with the holes already in my door?
The 4031 mounts on a 1-23/32" x 6-17/64" hole pattern, and it comes with a peel-n-stick template so you can lay the new pattern out against what is already drilled. Measure the existing pattern before you order: if it matches, it is a straight swap; if it does not, plan on new holes and, on a hollow metal door, sex bolts or blind fasteners rather than sheet metal screws into old torn holes. The non-handed body means the same unit works whichever way the door swings, so the only real question is the hole layout and which side you are mounting on.
8) What closer should be used in place of an LCN 4031 on an opening that needs delayed action?
The LCN 4031 is a hydraulic surface closer with no delay function, so on an opening where the door has to stand open a moment before it starts to close, the substitution is a delayed action model. The Orca Hardware BHDC1958DA/PA is a delayed action door closer supplied with a regular arm and parallel bracket, and the Orca Hardware BHDC2011DA/PA is the same delayed action arrangement in the BHDC2011 series. Both are tri-packed non-hold-open arm closers, which is the same arm arrangement as the 4031 regular arm and regular arm with parallel arm bracket versions.
9) The LCN 4031 adjusts through spring size 4 - what closer covers a door that needs size 5 or 6?
The LCN 4031 is a sized closer adjustable across spring sizes 1 through 4, covering interior doors to 5'0" and exterior doors to 4'0". When the door schedule calls for spring size 5 or 6, the BEST EHD9000 Series is an extra heavy-duty Grade 1 surface closer adjustable through sizes 1 to 6, and the Imperial USA TC4300 Series is a heavy duty Grade 1 closer adjustable through sizes 1 to 6. The Norton Rixson 8501A is a Grade 1 tri-mount closer adjustable through size 6 rated medium duty, and the Accentra 2701 Series architectural closer also adjusts through size 6 with tri-pack mounting.
10) The spec calls for a track arm closer - what replaces the LCN 4031 there?
Every arm offered on the LCN 4031 is a projecting arm: regular arm, regular arm with parallel arm bracket, extra duty, long, light duty, and the Cush-n-Stop and hold open versions. When the specification calls for an arm that runs in a track instead, the Corbin Russwin DC5230 Series is a Grade 1 surface door closer supplied with a slide track arm as standard and pull side mounting, and the Dormakaba 8916-JT is a heavy duty Grade 1 jamb track closer with frame face mounting on the pull side, adjustable size 1 to 6, with a flat non-hold open arm.
11) Is the LCN 4031 acceptable on a federal job with Buy American requirements?
The 4031 is BAA qualified, so it clears Buy American Act sourcing language on federal and federally funded work. Combined with the A156.4 Grade 1 rating and ADA compliance, it covers the three boxes a government or institutional spec usually checks on a surface closer.
12) What is the difference between the LCN 4031 and the other heavy duty cast iron closers, like the Sargent 281?
The 4031 is a cast iron cylinder closer with a forged steel main arm, a full complement bearing and a 1-1/8 inch diameter piston, rated ANSI/BHMA A156.4 Grade 1 and adjustable through sizes 1-4. The Sargent 281 Powerglide is the closest peer in that description, a cast iron surface closer of heavy duty construction rated Grade 1. Other heavy duty Grade 1 surface closers ZenSupply carries include the Falcon SC71A, the BEST HD8000 Series, and the Sargent 1431 Powerglide. Where they differ from one another is body material, arm range, and spring size range, so match the closer to the door size and the traffic rather than to the badge on the cover.
13) What do I have to specify when I order an LCN 4031?
Two things: the arm and the finish. Twelve arms are offered, REGARM, RWPA, LONG, LD, LD/PA, EDA, H, HWPA, CUSH, HCUSH, SCUSH and SHCUSH, and that choice sets your mounting position, whether the door holds open, and whether the arm carries a stop. Six powder coat finishes are offered: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze and 696 brass. No handing to call out, and the spring is field adjustable through sizes 1-4 after it is on the door.
14) Will the LCN 4031 still close the door properly in freezing weather?
That is what the all-weather fluid is for. The 4031 uses all-weather hydraulic fluid so the closing speed stays consistent as temperatures change, instead of the door slamming in the heat and failing to latch in the cold, which is the classic complaint on a standard-fluid closer sitting on an exterior entrance. Paired with the exterior door rating up to 4'0", it is built to live outside.
15) I am standardizing door closers across a portfolio of buildings. Does the LCN 4031 cover most of my openings with one part?
For a mixed portfolio it covers a lot of ground with one closer body. Spring power adjusts 1 through 4 in the field, it is non-handed so there is no left or right stock to carry, and it mounts three ways, hinge on the pull side, top jamb or parallel arm on the push side, which handles most frame conditions you will run into. What varies per opening is the arm and the finish, and the closer itself is common. The gaps to plan around: doors wider than 5'0" interior or 4'0" exterior need a larger closer, and there is no delayed action option in this model.
16) What is a lighter duty alternative to the LCN 4031 for a low traffic interior door?
The LCN 4031 is a heavy duty closer with a cast iron cylinder, built for high traffic commercial openings. On an interior door that does not see that traffic, the BEST SL6000 Series is a light duty Grade 1 surface mounted closer with adjustable spring sizes, the Arrow DC314 from the DC300 Series is a light duty Grade 1 surface mounted closer, and the Norton Rixson 160 Series is a light duty Grade 1 light commercial surface closer with an adjustable spring. The Falcon SC91A Series is also a light duty cast aluminum closer, but it is certified Grade 3 rather than Grade 1, which is the difference to check against the door schedule.
17) Which mounts three ways the same as an LCN 4031 does?
The LCN 4031 is a non-handed closer that mounts surface hinge side on the pull side, top jamb on the push side, or parallel arm on the push side, so one part number covers a left or right swinging door in any of those three positions. Cross brand, the Dexter DCH4000 Series and the Dexter DCM1000 Series are Grade 1 surface closers with tri mount capability for regular, parallel, or top jamb mounting. The Design Hardware 416 Series and 116 Series are heavy duty closers supplied with tri-packed non-hold open arms, and the Dormakaba 8616 AF86P is a heavy duty Grade 1 closer with a flat non-hold open arm in a tri-pack.
18) Is the Arrow DCN500DP a substitute for an LCN 4031?
No. The Arrow DCN500DP is a parallel drop plate for the DCN500 closer, a mounting accessory rather than a closer, so it does nothing on its own to control a door. The LCN 4031 is the closer itself: a surface mounted hydraulic unit with a cast iron cylinder and a 1-1/8 inch diameter piston, fixed to the door or frame on a mounting hole pattern of 1-23/32" x 6-17/64". A drop plate is ordered in addition to a closer, not in place of one.
19) What closer suits an aluminum storefront door where the LCN 4031 is the standard on the hollow metal openings?
The LCN 4031 is a heavy duty Grade 1 cast iron closer sized for interior doors to 5'0" and exterior doors to 4'0", mounted hinge side on the pull side, top jamb on the push side, or parallel arm on the push side. For aluminum storefront openings, the Norton Rixson 1600 Series aluminum storefront door closer is a heavy duty Grade 1 unit from the 1600BC Series with tri-style mounting, so the same three mounting positions are available while the closer is built for the storefront door.
20) How does the Cal-Royal 400 Series compare with an LCN 4031 on certification?
The Cal-Royal 400 Series is a commercial hydraulic door closer certified to ANSI Grade 2. The LCN 4031 is certified to ANSI/BHMA A156.4 Grade 1 and rated heavy duty on a cast iron cylinder. Where a facility standard or a door schedule calls out Grade 1, the 400 Series is a Grade 2 unit and does not answer that line; within the same brand, the Cal-Royal 500S barrier free closer with adjustable back-check and the Cal-Royal 700S dual valve sized closer with adjustable tube arm are both Grade 1.
21) Which closers from other brands give the same hold open function as an LCN 4031 hold open arm?
The LCN 4031 covers hold open through its arm selection: H hold open arm, HCUSH hold open Cush-n-Stop, HWPA hold open with parallel arm mounting bracket, and SHCUSH spring hold open Cush-n-Stop. Cross brand, the Orca Hardware BHDC1958HO/PA is a hold open door closer with parallel bracket built on a tri-packed hold open arm, the Accentra 51 Series is an industrial hold open closer with tri-packed mount options in sizes 1 to 6, and the Stanley Security A45-501HL is supplied with a long hold open arm as standard for top jamb mounting.
22) Does the LCN 4031 door closer come with a cover, and can I get it to match dark bronze hardware?
A metal cover is part of the closer, finished in powder coat. Six finishes are offered, so matching the rest of an opening is usually straightforward: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze and 696 brass. Dark bronze is the 695. Worth noting when you are comparing quotes, some competing closers are sold less cover, such as the Arrow DCN314 and DCN325, and the cover is then an added line item.
23) The LCN 4031 comes with a metal cover - which comparable closers ship less cover?
The LCN 4031 is supplied with a metal cover over the cylinder. Where an installation is taking the closer without a cover, the Arrow DCN314 is a Grade 1 surface door closer supplied less cover with a regular and parallel arm tri-pack and adjustable spring size 1 to 4, and the Arrow DCN325 is the same less cover arrangement adjustable through spring size 1 to 6. Going the other direction, the Dexter DCH1000 Series is a Grade 1 tri mount surface closer supplied with a full cover.
24) The LCN 4031 meets ADA opening force - which comparable closers are specified as barrier free?
The LCN 4031 is ADA compliant and meets ADA reduced opening force requirements, which is the same requirement other manufacturers label barrier free. The Cal-Royal 500S is a Grade 1 barrier free door closer with adjustable back-check, the Cal-Royal N900PBF is a Grade 1 barrier free hydraulic surface door closer from the 900 series, the Calibre CA9901 is a Grade 1 ADA surface mount closer with a tri-pack arm in sizes 2 to 5, and the Calibre CA4001 is a Grade 1 adjustable spring tension ADA hydraulic closer.
25) Are the Stanley Security 327 and 341 pivots an alternative to an LCN 4031?
No. The Stanley Security 327 is a heavy wardrobe pivot for doors 1-3/8" or 1-3/4" thick up to 150 lbs, and the Stanley Security 341 is a wardrobe pivot for flush recessed or overlay doors 1-1/8" to 1-3/8" thick. Pivots hang and swing a door. The LCN 4031 is a surface mounted hydraulic closer with a cast iron cylinder that controls the closing of the door and meets ADA reduced opening force, so a door hung on pivots that also has to self-close still takes a closer in addition to the pivots.
