LCN 4011-REG RH AL – Frequently Asked Questions

1) Can the LCN 4011 be mounted on the push side of the door with a parallel arm?
No. The 4011 is a surface closer mounted on the hinge side, pull side only, using a 2-1/2" x 6" hole pattern. If the door swings the wrong way for that, or the closer body has to sit out of the traffic path on the push side, you need a tri-mount closer instead. From what ZenSupply stocks, the Dexter DCH4000 and DCL2000 are Grade 1 surface closers that mount regular, parallel or top jamb, the Norton Rixson 8501A is a Grade 1 tri-mount with adjustable size 1-6 spring, and the Arrow DCN325 ships as a regular/parallel arm tri-pack. Decide the mounting side before you order the 4011, because no arm option on it converts to parallel.
2) Can I use an LCN 4011 with a hold open arm on a fire rated door?
Not the hold open arm. The 4011's UL and cUL listing covers self-closing doors with the regular arm or the fusible link arm. On a labeled opening that has to close and latch in a fire, order the fusible link arm, which holds the door open in normal use and releases it when the link reaches temperature. Plain hold open arms defeat self-closing and belong on non-rated openings only. All three arm types come in both right hand and left hand.
3) How do I know whether to order the LCN 4011 right hand or left hand?
Stand on the outside of the door, the side you would use a key on. If the hinges are on your right, it is a right hand door; hinges on the left, left hand. The 4011 is ordered handed, so every arm and finish combination comes as RH or LH and you pick one at the time of order. Get it wrong and the arm will not sit correctly on a pull-side hinge mount. On a pair of doors you are ordering one of each hand, not two of the same.
4) Is the LCN 4011 ADA compliant for an accessible entrance?
The 4011 is ADA compliant and carries a delay function for accessible and high-traffic openings, which gives a slower initial swing so someone using a walker or a wheelchair clears the door before it starts to close. It is also ANSI/BHMA Grade 1 and BAA qualified, so it clears both the grade requirement and the domestic-content requirement that show up on federal, school and healthcare specs. Spring force is set on the closer using the green dial indicator, so an inspector's opening-force reading can be corrected on the door without swapping the unit.
5) Should I order the adjustable size cylinder or a sized cylinder on the LCN 4011?
Door width decides it. The adjustable non-sized cylinder covers spring sizes 1 through 5 and handles interior doors to 4'6" and exterior doors to 3'6", and it is the one to buy when you are outfitting a mix of openings or do not have every width in front of you, since one part number covers the range and the green dial shows where it is set. Above those widths, up to 5'0" interior and 4'0" exterior, you need a sized cylinder specified for that opening. Standard cast iron cylinder or delayed action cylinder is a separate choice made at order time.
6) What is the closest cross-brand equivalent to the LCN 4011 surface door closer?
The LCN 4011 is a heavy duty surface closer built on a cast iron cylinder, ANSI/BHMA Grade 1, mounted surface hinge side on the pull side. The nearest match in another line is the Sargent 281 Powerglide, also a cast iron surface closer listed heavy duty and Grade 1. If the cast iron body is not the deciding factor, the BEST HD8000 Series and the Falcon SC71A Series are both heavy duty Grade 1 surface closers as well. When you cross over, carry the handing and arm choice with you, since the 4011 is ordered right hand or left hand with a regular arm, hold open arm, or fusible link arm.
7) The opening is wider than the LCN 4011 adjustable range covers - what closer should I use instead?
The LCN 4011 non-sized cylinder adjusts through sizes 1 to 5 and covers interior doors to 4 ft 6 in and exterior doors to 3 ft 6 in, with sized cylinders taking it to 5 ft 0 in interior and 4 ft 0 in exterior. If you want to stay on an adjustable body at the top of the range instead of moving to a sized cylinder, the BEST EHD9000 Series is an extra heavy duty Grade 1 closer with adjustable spring sizes 1 to 6, the Norton Rixson 8501A is a Grade 1 closer with an adjustable size 1 to 6 spring, and the Imperial USA TC4300 Series is a heavy duty Grade 1 closer in size 1 to 6.
8) What closer do I use on an aluminum storefront door if the LCN 4011 is not the right fit?
The LCN 4011 is a door-mounted surface closer, hinge side and pull side, laid out on a 2-1/2 in by 6 in hole pattern in the door. Storefront work usually wants a body sized for that frame instead. The Norton Rixson 1600 Series is a heavy duty Grade 1 aluminum storefront closer with tri-style mounting, and the Dorma 8916-JT is a heavy duty Grade 1 closer with a jamb track arm and frame face mounting on the pull side, adjustable size 1 to 6, which puts the body on the frame rather than on the door leaf.
9) What is the difference between the regular, hold open and fusible link arms on the LCN 4011?
Three different jobs. The regular arm is the plain self-closing arm for a door that should shut every time, which is most corridor and entry work. The hold open arm keeps the door standing open at a set point, used on non-rated openings such as a receiving door or a classroom that gets propped anyway. The fusible link arm holds the door open in daily use and drops it closed when heat melts the link, which is why it and the regular arm are the two arms covered by the 4011's UL and cUL listing for self-closing doors. Arm type, finish and hand are all specified when you order.
10) Will an LCN 4011 hold up on an exterior door in a cold climate?
It is built for it. The 4011 uses all-weather hydraulic fluid so the closing speed does not turn to molasses in January or race in August, and the body is a cast iron cylinder with a 1-1/2" diameter piston, a full-complement bearing and a double heat-treated steel pinion journal rather than an aluminum shell. On a sized cylinder it covers exterior doors up to 4'0"; on the adjustable non-sized cylinder, exterior width tops out at 3'6". Powder coat finish over the iron body is what you are getting outside.
11) I need matching door closers across a whole building in dark bronze, some with hold open. Can I get every combination in one finish?
Yes. The 4011 is offered in six powder coat finishes, 689 Aluminum, 690 Statuary Bronze, 691 Light Bronze, 693 Gloss Black, 695 Dark Bronze and 696 Brass, and each of those is available with the regular arm, the hold open arm or the fusible link arm, in right hand and left hand. So a run of 695 Dark Bronze units with hold open on the doors that need it and regular arms everywhere else all match, and the spare on the shelf fits whichever opening fails first. Standardizing on one model across a facility also means one set of templates and one adjustment procedure for your maintenance crew.
12) What are the alternatives to an LCN 4011 if I need a heavy duty Grade 1 closer from another brand?
Several, and they differ in body and mounting rather than in grade. The Sargent 281 Powerglide is the closest in construction, a heavy duty Grade 1 cast iron surface closer. The BEST HD8000 is a heavy duty Grade 1 surface closer and the BEST EHD9000 is an extra heavy duty Grade 1 with adjustable spring sizes 1-6. The Falcon SC71A is a heavy duty Grade 1 surface mount, and the Sargent 1431 Powerglide is a heavy duty Grade 1 with adjustable spring power. Where the 4011 differs is mounting: it is hinge-side pull mount, while several of these are offered tri-mount, which matters more than brand if your door swings the wrong way.
13) Is the LCN 4011 overkill for a light interior office door?
It can be. The 4011 is a heavy duty commercial closer with a cast iron body, built for institutional traffic; on a low-use interior office or closet door you are paying for cycles you will never run. Lighter Grade 1 surface closers ZenSupply carries include the BEST SL6000 with adjustable spring sizes, the Arrow DC314, and the Norton Rixson 160 Series for light commercial work. Where it stops being overkill is anywhere the door gets kicked all day, a school corridor, a healthcare wing, a multi-family entry, or any exterior opening, and anywhere a failed closer means a code violation rather than an inconvenience.
14) Is there a lighter duty closer than the LCN 4011 for a low traffic interior door?
The LCN 4011 is a heavy duty commercial closer, the tier specified for institutional and high traffic openings. For a quiet interior door where that much body is more than the opening asks for, the BEST SL6000 Series is a Grade 1 light duty surface closer with adjustable spring sizes, the Norton Rixson 160 Series is a Grade 1 light duty light commercial closer with an adjustable spring, and the Arrow DC314 in the DC300 Series is a Grade 1 light duty surface closer. All three stay at Grade 1 while dropping to a light duty body.
15) I am standardizing closers across a building - what sits between the LCN 4011 and a light duty closer?
The LCN 4011 is the heavy duty Grade 1 tier, cast iron cylinder, sized for the busiest openings in the building. For the interior doors in the same facility that do not see that traffic, the medium duty Grade 1 peers are the BEST HD7000 Series with adjustable spring power and backcheck control, the Falcon SC81A Series in a cast aluminum body, the Sargent 1131 for medium traffic commercial openings, and the Sargent 1331 on a universal aluminum body. Keeping the heavy duty 4011 on entrances and stair doors and a medium duty Grade 1 body on the interior leaves the whole facility at Grade 1.
16) Is the Cal-Royal 400 an equal substitute for the LCN 4011?
They are certified at different levels. The LCN 4011 is ANSI/BHMA Grade 1, and the Cal-Royal 400 Series commercial hydraulic closer is Grade 2. Where the drawing or the facility standard names Grade 1, 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 the Grade 1 bodies in that line. The Falcon SC91A is a further step away again at Grade 3 and light duty.
17) I need delayed closing on an accessible opening - does the LCN 4011 do that or should I buy a different closer?
The LCN 4011 carries a built-in delay function and is ADA compliant, so the delay is part of the closer rather than a separate model, and the handing and arm choice do not change because of it. If you would rather order delayed action as its own catalog item, the Orca Hardware BHDC1958DA/PA and BHDC2011DA/PA are delayed action closers with a regular arm and parallel bracket for a 1-3/4 in door, both listed as tri-packed non-hold open arm.
18) What other Grade 1 closers mount pull side with a regular arm the way the LCN 4011 does?
The LCN 4011 mounts surface, hinge side on the pull side, and is ordered with a regular arm in right or left hand. Corbin Russwin gives you the same geometry in several tiers: the DC6200 Series and the DC8200 Series are Grade 1 surface closers with a double lever regular arm and pull side mounting for a 1-3/4 in door, and the DC3200 is a Grade 1 surface closer with a regular arm on the same door thickness. The DC5230 is Grade 1 and pull side as well but comes standard with a slide track arm instead of a projecting regular arm, which is a different arm profile at the door face.
19) Does the LCN 4011 come with a cover, and what are the cover choices?
A cover is part of the closer, offered in plastic or metal. Plastic is the standard cover and is what most interior commercial openings get; the metal cover is the one to specify where the closer is within reach of abuse, in a lobby, a school corridor or a detention-adjacent space, and metal covers are handed to match the closer. Worth noting when you cross-shop: some competing closers are sold less cover, such as the Arrow DCN314 and DCN325, so a cheaper number on paper may not include the piece you need to finish the door.
20) Is there a pull side closer with a slide track arm instead of the 4011's projecting arm?
Yes, if the projecting arm is the problem. The LCN 4011 uses a conventional two-piece arm, regular, hold open or fusible link, on a hinge-side pull mount. Where an exposed arm invites vandalism or clutters a tight reveal, the Corbin Russwin DC5230 is a Grade 1 surface closer with a slide track arm as standard, also pull side mounting, listed for 1-3/4" doors. Track arms generally swing less far off the door face; the tradeoff is that a track has to be surface mounted on the frame with enough clear head room, so check the head condition before you switch.
21) Can I order the Arrow DCN500DP in place of an LCN 4011?
No - the Arrow DCN500DP is a parallel drop plate for the DCN500, a mounting bracket rather than a closer body, so it does not replace a closer on the opening. The LCN 4011 is the complete surface closer, cast iron cylinder with the arm and cover ordered with it. If an Arrow closer is what you are after, the DCN314 is a Grade 1 surface closer with a regular/parallel tri-pack arm in adjustable spring size 1 to 4 and the DCN325 is the same arrangement in size 1 to 6.
22) Which closers come with a cover like the LCN 4011 and which ship without one?
The LCN 4011 is supplied with a cover, plastic or metal, over a cast iron cylinder. That is worth checking on any cross-brand swap because covers are handled differently from line to line: the Arrow DCN314 and DCN325 are both catalogued less cover, the Dexter DCH1000 Series is a Grade 1 tri mount closer with a full cover, and the Design Hardware 316 Series is a medium to heavy duty closer supplied with a cover. If the exposed cylinder matters on a public corridor, match the cover before you match the spring size.
