LCN 4040XP-RWPA-693 – Frequently Asked Questions
1) Is the LCN 4040XP door closer handed, or will one unit work on a left hand and a right hand door?
The closer itself is non-handed, so the same body and cylinder go on a left hand or right hand opening. Handing only enters at the arm. Most of the arm range is non-handed, but the hold open extra duty arms are ordered by hand: HEDA-LH and HEDA-RH, and HEDA62G-LH and HEDA62G-RH with the 62G thick hub shoe. If you're buying those, get the hand of the door right before you order; everything else on the closer is symmetrical.
2) Can the LCN 4040XP be mounted on the push side of the door?
Two ways, yes. The 4040XP mounts hinge side (pull side), top jamb (push side), or parallel arm (push side), all from the same closer. Parallel arm is the usual pick when the door swings out into a corridor or a stair: the arm folds back flat against the door face instead of standing out into the opening where it gets hit. Top jamb puts the closer on the frame face above the door instead of on the door itself. The arm has to suit the mounting, so specify accordingly, for example RWPA (regular arm with the parallel arm bracket) or HWPA (hold open with the parallel arm mounting bracket).
3) The door has no wall stop and keeps swinging into the drywall. Which 4040XP arm stops the door?
Order one of the Cush-n-Stop arms. The 4040XP arm list includes CUSH (Cush-n-Stop), HCUSH (hold open Cush-n-Stop), SCUSH (spring Cush-n-Stop) and SHCUSH (spring hold open Cush-n-Stop). A cush arm carries the stop in the arm's soffit shoe, so the arm takes the overswing instead of the door slamming into a wall, a radiator or an adjacent door. The spring versions cushion that stop rather than taking it dead. All four are forged steel like the rest of the arm range, which is what keeps them from bending in a high abuse opening.
4) Should I put a hold open arm on a fire rated door?
No. A mechanical hold open arm defeats the whole point of a closer on a fire door, which has to be free to close and latch when the alarm sounds. That opening wants a non-hold-open arm, with any hold open handled by an electromagnetic holder released by the fire alarm. On non-rated openings, the 4040XP hold open choices are H, HCUSH, HLONG, HWPA, SHCUSH, and the handed HEDA and HEDA62G arms. Keep the plain CUSH, EDA, REGARM, LONG, XLONG, RWPA and RW62A arms for anything rated.
5) What is the closest heavy duty Grade 1 surface closer to the LCN 4040XP from another manufacturer?
The LCN 4040XP is a heavy duty surface-mounted closer with an iron body and a cast-iron cylinder, adjustable across spring sizes 1 through 6, certified to ANSI/BHMA A156.4 Grade 1 and independently tested to 10 million cycles. Three peers sit in the same heavy duty Grade 1 class. The Sargent 281 Powerglide is a heavy duty Grade 1 surface closer that also uses cast iron construction. The BEST EHD9000 Series is an extra heavy-duty Grade 1 surface closer with adjustable spring sizes 1 through 6, so it covers the same spring range without changing the unit. The Falcon SC71A Series is a heavy duty Grade 1 surface-mount closer. When you cross to any of them, specify the arm style and the mounting position separately, since arm packages are ordered differently brand to brand.
6) The drawing calls for an ANSI Grade 1 closer. Which surface closers that look similar to the LCN 4040XP will not meet that line item?
The LCN 4040XP is certified to ANSI/BHMA A156.4 Grade 1. Two surface closers that read as lookalikes carry a different grade. The Falcon SC91A Series is a light duty cast aluminum surface-mount closer at Grade 3. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic door closer. Both are hydraulic surface closers and both will hang on a standard opening, but if the submittal line reads Grade 1 they answer a different specification. Grade 1 peers in the same surface-mount format include the BEST HD8000 Series heavy duty closer, the Dexter DCH4000 Series tri-mount closer, and the Sargent 1431 Powerglide heavy-duty closer.
7) I need one closer that covers everything from a small office door to a wide exterior entrance. Which models adjust across the full size 1 to 6 range?
The LCN 4040XP is non-handed and non-sized and adjusts to spring sizes 1 through 6, covering interior doors to 5 ft 0 in. and exterior doors to 4 ft 0 in. on one unit. Peers with the same 1 through 6 spring range include the BEST EHD9000 Series, the Accentra 2701 Series with tri-pack mounting, the Accentra 51 Series, the Norton Rixson 8501A tri-mount closer, the Dormakaba 8916-JT, and the Imperial USA TC4300 Series heavy duty ADA closer. Models built on a narrower range will not cover the same spread of openings from one part number: the Accentra 1101BF and the Arrow DCN314 are adjustable spring size 1 through 4, the Dormakaba 7414 is size 1 through 4, and the Calibre CA9901 is size 2 through 5.
8) I need delayed action for an accessible entrance. Which closers besides the LCN 4040XP delayed cylinder offer it?
The LCN 4040XP is ordered with either a standard cylinder (CYL) or a delayed action cylinder (CYLDEL), both adjustable across spring sizes 1 through 6, so delay is a cylinder choice on the same body rather than a separate model. Two peers are built as delayed action models. The Orca Hardware BHDC1958 Series delayed action closer comes as a regular arm with a parallel bracket and is listed for 1-3/4 in. doors. The Orca Hardware BHDC2011 Series delayed action closer is also a regular arm with parallel bracket for 1-3/4 in. doors. Both are tri-packed non-hold-open arm configurations, so the delay is separate from any hold-open function.
9) I'm replacing a closer that's already on the door. Will the LCN 4040XP land on the existing holes?
Measure the prep against a 2-1/4 by 5 inch mounting hole pattern, which is what the 4040XP uses. If the old unit shares that pattern you're mounting straight to it. If it doesn't, you have room to work: the closer is non-handed and mounts three ways (hinge/pull, top jamb, parallel arm), so a mounting position that clears the old holes is usually available, and the TBSRT through bolt screw package pulls the closer up tight on a door that has already been drilled and no longer holds a thread cleanly.
10) How do I get a door closer that holds the door open a few seconds before it starts to close?
Specify the CYLDEL delayed action cylinder on the 4040XP instead of the standard CYL. Delay is a cylinder choice, not a separate model, and both cylinders adjust across spring sizes 1 through 6, so you give up no range by taking the delay. It buys time for a wheelchair, a gurney, a housekeeping cart or a hand truck to clear the opening, which is why it shows up on healthcare, school and multi-tenant residential doors. If nobody needs that pause, the standard CYL is the one to order.
11) SRT or TBSRT screws on an LCN 4040XP, which pack do I need?
SRT is the self reaming and tapping pack, which threads into hollow metal doors and frames where the metal will hold a screw. TBSRT adds through bolts, and that is what you want on a wood door, on an opening that has been drilled and re-drilled by previous closers, or on any high abuse door where screws eventually work loose and pull out. Through bolting also spreads the load across the door instead of hanging the closer on the face skin alone. Pick one when you order; the screw pack is a required choice, not an accessory you add later.
12) Will the LCN 4040XP meet ADA opening force requirements on an interior door?
The 4040XP is ADA compliant, and the adjustment range is what makes that workable. Because spring force is adjustable from size 1 through 6 rather than fixed at the factory, you can bring the force down to what an accessible interior opening needs and still have headroom to go back up on a heavier door. Set the spring with the green dial, then tune the sweep and latch speed separately so the door still closes and latches at the reduced force. Worth knowing: dialing the spring low on a windy exterior opening can leave the door short of latching, so exterior doors usually want more spring than an interior one.
13) Is the LCN 4040XP heavy duty enough for a school or hospital entrance that cycles all day?
It is built for exactly that traffic. The 4040XP is independently certified to 10 million cycles, five times the 2 million cycles ANSI/BHMA A156.4 Grade 1 asks for. Inside is a cast iron cylinder with a full-complement bearing, a 1-1/2 inch piston and a double heat-treated steel pinion, and every arm type is solid forged steel rather than cast. It is classed heavy duty and commercial-only. On a door that sees thousands of cycles a day, the cylinder and the pinion are what wear out first, and that is where the money went here.
14) Does the LCN 4040XP qualify for a federally funded project with Buy American requirements?
BAA qualified, yes. Alongside that it carries ANSI/BHMA A156.4 Grade 1 certification and UL and cUL listing, which together cover most of the boilerplate on government, municipal and institutional door hardware specs. If your submittal asks for a Grade 1 surface closer with domestic-preference qualification, the 4040XP answers it without a substitution request.
15) What do I actually have to specify when ordering an LCN 4040XP?
Four decisions, and the closer will not ship without them. Arm type, from 18 options spanning regular, long, extra long, extra duty, the parallel arm brackets, the Cush-n-Stop family and their hold open versions. Cylinder, CYL standard or CYLDEL delayed action, both adjustable 1 through 6. Finish, one of seven powder coat colors. Screw package, SRT or TBSRT. Cover comes plastic or metal. Nothing about the closer body is sized or handed, so those four picks are where the whole configuration lives.
16) Will a 4040XP closer still work right on an exterior door in cold weather?
The all-weather fluid is the reason it does. LCN's Liquid X formulation holds sweep and latch speed through temperature swings, which is the failure mode a cheap closer shows first: it slams in August heat and then won't push the door far enough to latch at 10 degrees, so the entrance sits unsecured. The 4040XP is rated for exterior doors up to 4 feet wide, and you can bring spring force up on the green dial to overcome wind load without swapping the unit.
17) What are the alternatives to an LCN 4040XP for a heavy traffic commercial door?
Staying in heavy duty Grade 1 surface closers, ZenSupply carries the BEST EHD9000 (extra heavy duty, adjustable spring sizes 1 to 6), the Sargent 281 Powerglide cast iron closer, the Sargent 1431 Powerglide, the Falcon SC71A, and the Dormakaba 8616 with the flat arm tri-pack. All of those are heavy duty and Grade 1. What separates the 4040XP is the independent 10 million cycle certification, which is five times the 2 million cycles Grade 1 itself requires, plus the cast iron cylinder and forged steel arms. If the spec just says Grade 1 heavy duty, several of these clear it; if the spec or the traffic calls for cycle life beyond the standard, that is the 4040XP's argument.
18) The door is a low-traffic interior office door. Is there a lighter closer than the LCN 4040XP for that opening?
The LCN 4040XP is a heavy duty commercial closer built for high-traffic openings, with a cast-iron cylinder and independent certification to 10 million cycles. For light-traffic interior doors, the BEST SL6000 Series is a light duty Grade 1 surface closer with adjustable spring sizes, the Norton Rixson 160 Series is a light duty Grade 1 light commercial closer with an adjustable spring, and the Arrow DCN325 is a light duty Grade 1 surface closer supplied less cover with a regular and parallel arm tri-pack and adjustable spring size 1 through 6. All three keep Grade 1 certification while being built to a light duty rating, so check the cycle demand on the opening before you decide which duty level fits.
19) What are the hold open alternatives to the LCN 4040XP hold open arms?
On the LCN 4040XP, hold open is an arm selection: H hold open arm, HCUSH hold open Cush-n-Stop, HEDA hold open extra duty in left and right hand, HLONG hold open long arm, HWPA hold open with parallel arm bracket, and SHCUSH spring hold open Cush-n-Stop. Comparable closers built around hold open include the Accentra 51 Series industrial closer, which is a tri-packed hold open arm with tri-packed mount options and size 1 through 6, and the Orca Hardware BHDC1958 Series hold open closer with parallel bracket, a tri-packed hold open arm for 1-3/4 in. doors. For a top jamb application the Stanley Security A45-501HL is supplied with a long hold open arm as standard, top jamb mounting.
20) Is there a closer like the LCN 4040XP with an aluminum body instead of a cast iron one?
The LCN 4040XP is built on an iron substrate with a cast-iron cylinder and a forged steel arm. Aluminum-bodied peers in the same surface-mount format include the Sargent 1331 Series, a medium duty Grade 1 closer with a universal aluminum body; the Falcon SC81A Series, a medium duty Grade 1 cast aluminum surface-mount closer; and the Falcon SC61A Series, a cast aluminum closer rated light to medium duty at Grade 1. All three are Grade 1 like the 4040XP but sit at a medium or light-to-medium duty rating, so match the body material choice to the traffic on the opening rather than treating it as a finish decision.
21) What closer should I look at for an aluminum storefront entrance instead of the LCN 4040XP?
The LCN 4040XP mounts hinge side (pull), top jamb (push), or parallel arm (push) on a 2-1/4 in. by 5 in. hole pattern, which is a hollow metal and wood door pattern first. For aluminum storefront entrances, the Norton Rixson 1600 Series aluminum storefront closer is a heavy duty Grade 1 closer with tri-style mounting, built for that door type. The Norton Rixson 1601P is a Grade 1 medium duty tri-mount closer with a 180 degree swing, which matters when the entrance opens back against a wall or sidelite. Check the top rail and frame face dimensions on the storefront before committing to either.
22) Which Grade 1 surface closers are barrier free rated if I am standardizing an accessible facility?
The LCN 4040XP is ADA compliant and BAA qualified, adjustable across spring sizes 1 through 6 so opening force can be dialed in per door. Two Cal-Royal peers are built as barrier free models: the 500S Series, a Grade 1 barrier free closer with adjustable back-check, and the N900PBF from the 900 Series, a barrier free Grade 1 hydraulic surface closer. The Imperial USA TC4300 Series is a Grade 1 heavy duty ADA closer adjustable size 1 through 6. The Calibre CA9901 is a Grade 1 ADA surface mount closer with a tri-pack arm at size 2 through 5. Set the spring size to the opening force the facility requires in every case.
23) What finishes does the LCN 4040XP powder coat closer come in, and which one matches standard commercial hardware?
Seven powder coat colors: 622 matte black, 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze and 696 brass. 689 aluminum is the workhorse on commercial openings and is what most existing closers in an office or school building will be, so it is the safe pick when you are adding one unit to a floor that already has a dozen. Go to 690 or 695 bronze when the door hardware and frames are dark, and 622 or 693 when the spec calls for black. Powder coat is the finish process on all seven.
24) I need a flat arm profile on a push side parallel arm application. What is the alternative to the LCN 4040XP?
The LCN 4040XP handles push side work through top jamb and parallel arm mounting, with parallel arm variants including RWPA regular arm with parallel arm bracket, HWPA hold open with parallel arm bracket, and the extra duty EDA arm. Where the detail calls for a flat arm instead, the Dormakaba 8616 with flat arm is a heavy duty Grade 1 closer supplied as a flat arm non-hold-open tri-pack, and the Dormakaba 8916-JT is a heavy duty Grade 1 closer with a flat non-hold-open arm on a jamb track, frame face mounted pull side. The Corbin Russwin DC8200 Series and DC6200 Series are Grade 1 surface closers supplied with a double lever regular arm, pull side mounting, for 1-3/4 in. doors.
25) I stock closers on the truck and do not know the mounting until I am at the door. Which models ship tri-packed instead of with the arm specified like the LCN 4040XP?
On the LCN 4040XP the arm is a selection made at order time, from regular, long, extra long, extra duty, hold open and Cush-n-Stop styles, and the body itself mounts hinge side, top jamb or parallel arm. Peers that ship one box covering more than one mounting include the Design Hardware 116 Series and 416 Series, both heavy duty with a tri-packed non-hold-open arm; the Design Hardware 316 Series, medium to heavy duty with a tri-packed non-hold-open arm and a cover; the Dexter DCH4000 Series, a Grade 1 tri-mount closer for regular, parallel or top jamb mounting; and the Accentra 2701 Series architectural closer with tri-pack mounting options and adjustable spring sizes 1 through 6.
26) The traffic on this door is moderate, not heavy. What is the medium duty Grade 1 step down from the LCN 4040XP?
The LCN 4040XP is rated heavy duty and certified to ANSI/BHMA A156.4 Grade 1. Medium duty peers that hold the same Grade 1 certification include the Norton Rixson 8501A, a tri-mount surface closer with an adjustable size 1 through 6 spring; the Sargent 1131, an adjustable surface closer for medium-traffic commercial applications; the BEST HD7000 Series, with adjustable spring power and backcheck control; and the Dormakaba 7303 Series, a standard duty surface-mounted closer in a painted finish. The Norton 8501A is the one of the four that matches the 4040XP spring range of 1 through 6, so it covers the same spread of door widths from a single unit.
