LCN 4211-652 – Frequently Asked Questions

1) Will the LCN 4211 closer work on an exterior door, or is it interior only?

The 4211 handles both. With sized cylinders it covers interior doors to 5'0" and exterior doors to 4'0". The non-sized cylinder version is adjustable for interior doors to 4'6" and exterior doors to 3'6". Exterior use is backed by all-weather fluid, so the closing speed does not drift as temperatures swing. If your exterior opening is wider than 4'0", the 4211 is not the closer for it.

2) Is the LCN 4211 a good choice for a jail, detention, or vandal-prone opening?

That is what it was built for. The 4211 runs a cast iron body with forged steel parallel arms and a one-piece forged steel piston, then adds heavy gauge metal security covers and tamper-resistant regulating screws so nobody can back off the closing force with a screwdriver. The mounting pack is TORX machine screws rather than standard Phillips. Correctional, institutional, education, healthcare and municipal facilities are the intended applications.

3) What do I have to specify when ordering an LCN 4211 closer?

Three things beyond finish. Cylinder is required: standard cast iron cylinder assembly (CYL), advanced variable back check (CYLAVB), or delay action (CYLDEL). Arm is required too: extra duty arm (EDA), Cush-n-Stop (CUSH), or hold open Cush-n-Stop (HCUSH). Handing is optional and defaults to right hand, with left hand available. Finish comes in six plated options: 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, 651 bright chrome and 652 satin chrome.

4) Do I need a separate door stop with the LCN 4211, or does the closer stop the door?

Order the Cush-n-Stop arm (CUSH) and the arm itself stops the door at the backcheck point, which keeps you from having to hang a wall or floor stop in a corridor where one would get kicked off. The hold open version (HCUSH) does the same and holds the leaf open at the stop position. If you want the door to close every time with no hold open, the extra duty arm (EDA) is the choice, and you would provide a stop separately.

5) Does the LCN 4211 meet ADA opening force and Grade 1 for a spec?

Both are on record. The 4211 is tested and certified under ANSI Standard A156.4 Grade 1, and it meets Americans with Disabilities Act requirements for accessible door operation. It is also UL and cUL listed for self-closing doors, and BAA qualified, which matters on federally funded work.

6) The LCN 4211 mounts parallel arm on the push side. What closer should I use if the door has to be mounted on the pull side?

The 4211 is a surface parallel arm closer mounted on the push side. For a pull side installation, the Corbin Russwin DC6200 Series is a Grade 1 surface closer with a double lever regular arm in pull side mounting, and the DC8200 Series is the same pull side regular arm arrangement in the DC8000 family; both list a 1-3/4 inch door thickness. The Corbin Russwin DC5230 is a Grade 1 surface closer with a slide track arm as standard, also pull side mounting, if the opening calls for a track rather than a projecting arm. The Dormakaba 8916-JT is a Grade 1 heavy duty jamb track closer with frame face mounting on the pull side, adjustable size 1 to 6.

7) What is a direct Grade 1 heavy duty cast iron alternative to the LCN 4211 door closer?

The Sargent 281 Powerglide is a cast iron surface door closer rated heavy duty and Grade 1, which puts it in the same construction and rating class as the 4211 with its cast iron body and Grade 1 certification. The Falcon SC71A of the SC70A Series is another heavy duty Grade 1 surface-mount closer, and the BEST HD8000 Series is a heavy duty Grade 1 surface mounted closer as well. The 4211 differs in that it is built around high security: tamper-resistant regulating screws, heavy gauge metal security covers, and a TORX machine screw pack. If the opening does not need the security package, those peers cover the same heavy duty Grade 1 surface application.

8) Which door closer should I use instead of the LCN 4211 on an opening that only needs standard commercial duty, not correctional grade?

For a standard commercial opening, the BEST HD7000 Series is a medium duty Grade 1 surface mounted closer with adjustable spring power and backcheck control, and the Sargent 1131 is a medium duty Grade 1 adjustable surface closer aimed at medium-traffic commercial applications. The Norton Rixson 1601P of the 1600 Series is medium duty Grade 1 with tri-mount design and 180 degree swing. The 4211 is a heavy duty closer with a cast iron body and security covers intended for correctional, institutional, and vandal-prone environments; the medium duty peers above carry the same Grade 1 rating without that security hardware.

9) Is a light duty Grade 1 closer like the Arrow DC314 an acceptable substitute for the LCN 4211?

They carry the same ANSI grade but not the same duty class. The Arrow DC314 in the DC300 Series is a Grade 1 surface mounted closer rated light duty, and the BEST SL6000 Series is likewise Grade 1 light duty. The 4211 is a heavy duty closer with a cast iron body, forged steel parallel arms, and a one-piece forged steel piston, specified for correctional and vandal-prone environments. Grade 1 describes the cycle and performance test the closer passed; it does not make a light duty body equivalent to a cast iron heavy duty one on an abused institutional opening. For a like-for-like duty match, look at the heavy duty Grade 1 peers such as the BEST EHD9000 Series.

10) The LCN 4211 uses sized cylinders. What heavy duty closer takes an adjustable spring size instead so I can stock one part across a building?

For standardizing on one closer across mixed openings, the BEST EHD9000 Series is an extra heavy duty Grade 1 surface mounted closer with adjustable spring sizes 1 through 6, the Sargent 1431 Powerglide is a heavy duty Grade 1 surface closer with adjustable spring power, and the Imperial USA TC4300 Series is a heavy duty Grade 1 size 1 to 6 ADA closer. The Dormakaba 8616 AF86P FC SNB1 689 is a Grade 1 heavy duty closer supplied with a flat non-hold open arm in a tri-pack. The 4211 is furnished in closer size 1 with sized cylinders covering interior doors to 5 feet and exterior doors to 4 feet, and a non-sized cylinder adjustable for interior doors to 4 feet 6 inches and exterior doors to 3 feet 6 inches.

11) Does a Grade 2 door closer such as the Cal-Royal 400 Series work in place of the LCN 4211?

No, they are not on the same ANSI tier. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic door closer. The 4211 is tested and certified under ANSI Standard A156.4 Grade 1 and is a heavy duty closer. If a facility specification or code review calls for Grade 1, a Grade 2 closer will not satisfy it. Within Cal-Royal, the 500S is a Grade 1 barrier free closer with adjustable back-check and the 700S of the 700 Series is a Grade 1 dual valve sized closer with an adjustable tube arm, either of which holds the Grade 1 rating.

12) Which cylinder should I pick on an LCN 4211 for a door people carry carts through?

Delay action (CYLDEL) is the one. It holds the leaf near full open for a few seconds before the closing cycle starts, which is what you want at a healthcare corridor, a classroom, or any opening where someone is pushing a cart or a wheelchair through. If the problem is instead a door getting slammed into the adjacent wall by wind or traffic, the advanced variable back check cylinder (CYLAVB) is the better pick, since it cushions the opening swing rather than slowing the close.

13) How far will a door with an LCN 4211 closer swing open?

To 180 degrees, subject to what the opening itself allows. Wall returns, adjacent leaves and the arm option govern the real number: a Cush-n-Stop arm stops the door short of that on purpose to protect the wall. Plan the swing around the obstruction, not around the closer.

14) What is the difference between the LCN 4211 and a standard aluminum body commercial closer?

Body material and security. The 4211 is cast iron with forged steel arms and security covers aimed at correctional and vandal-prone work. A conventional Grade 1 commercial closer such as the Falcon SC71A heavy duty surface closer or the Sargent 1431 Powerglide heavy duty closer covers ordinary heavy traffic without the tamper-resistant hardware. For lighter openings, the Falcon SC81A is a medium duty Grade 1 unit. Pay for the 4211 where the closer itself is a target.

15) What is a comparable heavy duty cast iron closer to the LCN 4211 if I need another brand?

For a cast iron heavy duty unit, the Sargent 281 Powerglide is Grade 1 cast iron heavy duty. The BEST EHD9000 Series is an extra heavy duty Grade 1 surface closer with adjustable spring sizes 1 through 6, and the BEST HD8000 Series is heavy duty Grade 1. None of those carry the 4211's security cover and tamper-resistant screw package, so they substitute on duty level, not on the high-security side.

16) Is the LCN 4211 spring power adjustable or fixed at size 1?

The 4211 is listed at closer size 1, and LCN's Green Dial spring force indicator on the unit shows where the spring is set so you can adjust to the opening accurately. If your schedule calls for one closer that covers a range of door widths across a building, an adjustable size 1 through 6 unit such as the Norton Rixson 8501A or the BEST EHD9000 Series is the type to standardize on instead.

17) Does handing matter when ordering an LCN 4211 door closer?

Yes, it is a selection on the order. Right hand is the default and left hand is available, so confirm the swing at the opening before you place it. Stand outside the door: if the hinges are on your right and the door swings away from you, it is right hand.

18) I need delayed action closing on an accessible door. What are my options besides the LCN 4211?

The 4211 offers a delay function and can be ordered with a delay action cylinder. Among comparable closers, the Orca Hardware BHDC1958DA/PA is a delayed action closer with a regular arm and parallel bracket, tri-packed non-hold open, for 1-3/4 inch doors, and the BHDC2011DA/PA is the delayed action version in the BHDC2011 Series with the same regular arm and parallel bracket arrangement and 1-3/4 inch door thickness. The 4211 differs in construction, being a heavy duty cast iron closer with tamper-resistant hardware for institutional openings, while the Orca units are ordered as a specific delayed action model rather than as a cylinder selection.

19) Which closers are alternatives to the LCN 4211 on an aluminum storefront entrance?

For an aluminum storefront, the Norton Rixson 1600 Series in the 1600BC family is a heavy duty Grade 1 aluminum storefront door closer with tri-style mounting, and the Falcon SC81A of the SC80A Series is a medium duty Grade 1 cast aluminum surface-mount closer. The 4211 is a cast iron bodied heavy duty closer with forged steel parallel arms, mounted surface parallel on the push side, and is specified for correctional and institutional openings rather than narrow stile storefront applications.

20) I want a hold open closer instead of the LCN 4211 standard arm. What comparable models come with a hold open arm?

The 4211 can be ordered with a hold open Cush-n-Stop arm. Among comparable closers furnished with hold open arms, the Accentra 51 Series is an industrial door closer with a tri-packed hold open arm in sizes 1 to 6, the Orca Hardware BHDC1958HO/PA is a tri-packed hold open closer with a parallel bracket for 1-3/4 inch doors, and the Stanley Security A45-501HL in the D-455 family is furnished with a long hold open arm as standard for top jamb mounting. Note that a hold open arm is generally not acceptable on a door required to be self-closing; the 4211 carries UL and cUL listing for self-closing doors.

21) What is the difference between the LCN 4211 and the Arrow DCN314 or DCN325 when the cover is not needed?

The Arrow DCN314 is a Grade 1 surface closer supplied less cover with a regular or parallel arm tri-pack and adjustable spring size 1 to 4, and the DCN325 is the same less cover tri-pack arrangement with adjustable spring size 1 to 6; both are rated light duty. The 4211 goes the other direction on covers: it is furnished with heavy gauge metal security covers and tamper-resistant regulating screws, and the fasteners are TORX machine screws, which is the point of the closer in vandal-prone settings. Choose the Arrow units where an exposed closer body is acceptable and the traffic is light duty.

22) I searched for a Stanley heavy duty door control and got pivots. Are those an alternative to the LCN 4211?

They are not. The Stanley Security 327 is a heavy wardrobe pivot for 1-3/8 inch or 1-3/4 inch doors up to 150 pounds, and the Stanley Security 341 is a wardrobe pivot for flush recessed or overlay doors 1-1/8 inch to 1-3/8 inch thick. A pivot hangs and swings the door; it applies no closing force. The 4211 is a surface mounted hydraulic closer that controls the door back to the frame, mounted surface parallel on the push side with all-weather fluid. If the goal is controlled self-closing, the substitute has to be another surface closer such as the Sargent 281 or the Falcon SC71A, both heavy duty Grade 1.

23) For a school or healthcare corridor door that has to be ADA compliant, what closers compare to the LCN 4211?

The 4211 is ADA compliant, commercial rated, and permits a 180 degree door opening, with Grade 1 certification under ANSI A156.4. Comparable ADA closers include the Calibre CA9901, a Grade 1 tri-pack arm ADA surface mount closer in sizes 2 to 5, the Calibre CA4001, a Grade 1 adjustable spring tension ADA hydraulic closer, the Calibre CA8001P, a Grade 1 parallel arm size 1 ADA surface mount closer, and the Cal-Royal N900PBF, a Grade 1 barrier free hydraulic surface closer in the 900 Series. The Imperial USA TC4300 Series is a heavy duty Grade 1 size 1 to 6 ADA closer. The 4211 adds the tamper-resistant screws and security covers intended for vandal-prone corridors.

24) What closer is the counterpart to the LCN 4211 if the job needs a top jamb or regular arm mounting instead of parallel arm?

The 4211 is a surface parallel arm closer for push side mounting. For tri-mount flexibility, the Dexter DCH1000 Series is a Grade 1 surface closer that mounts regular, parallel, or top jamb and includes a full cover, and the DCH4000, DCL2000, and DCM1000 Series are Grade 1 tri-mount surface closers as well. The Norton Rixson 8501A is a Grade 1 medium duty tri-mount closer with adjustable size 1 to 6 spring in the 8000 Series. The Corbin Russwin DC3200 is a Grade 1 regular arm surface closer for 1-3/4 inch doors in the DC3000 Series.

25) Can I match the LCN 4211 to the brass and chrome hardware already on my other doors?

Six plated finishes are offered, so most existing schedules match: 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, 651 bright chrome and 652 satin chrome. Those are the standard BHMA finish numbers, so a 652 closer lines up with 652 lever trim and 652 hinges across the rest of the building.

26) Which closers compare to the LCN 4211 for a heavy duty interior door that also needs a plated decorative finish?

The 4211 is offered in plated finishes including 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, 651 bright chrome, and 652 satin chrome, on a heavy duty cast iron body. Among comparable heavy duty units, the Design Hardware 416 Series and 116 Series are heavy duty closers with tri-packed non-hold open arms, and the 316 Series is rated medium to heavy duty and is supplied with a cover. The Falcon SC71A is a heavy duty Grade 1 surface-mount closer in the SC70A Series. These differ from the 4211 in that its plated finish range is selected as the ordering option on the closer itself.
