LCN 4211-689 – Frequently Asked Questions

1) Will the LCN 4211 closer handle a 4-foot exterior door?

Yes. The 4211's sized cylinders cover exterior doors up to 4'0" and interior doors up to 5'0". If you order it with the non-sized cylinder instead, the range drops to 4'6" interior and 3'6" exterior, so on a full 4-foot exterior opening you want the sized cylinder. All-weather fluid means it keeps its speed through temperature swings on an exterior opening.

2) What do I need to specify when ordering an LCN 4211?

Four things get chosen on the order: handing (left or right), the cylinder, the arm, and the finish. Cylinder choices are the standard cast iron assembly (CYL), advanced variable back check (CYLAVB), or delay action (CYLDEL). Arm choices are the extra duty arm (EDA), the Cush-n-Stop arm (CUSH), or the hold open Cush-n-Stop (HCUSH). Powder coat finishes run 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 696 brass.

3) Which arm do I order if there's no wall stop behind the door?

Order the Cush-n-Stop arm (CUSH), or the hold open version (HCUSH) if you also want the door to stay open. Both build the stop into the arm, so the arm shoe takes the abuse instead of the door hitting a wall or a return. The extra duty arm (EDA) is the default and assumes you already have a separate stop on the opening. On a correctional or vandal-prone door, the built-in stop is usually the safer call since a surface wall stop is one more thing to pull off the wall.

4) Is the LCN 4211 door closer ADA compliant and Grade 1?

Both. The 4211 is ADA compliant and meets ANSI/BHMA A156.4 Grade 1, and it is UL listed for self-closing doors. It is also BAA qualified, which matters if you're buying under federal or municipal procurement rules. That combination is what most institutional and government specs are asking for on a closer.

5) What makes a high security door closer different from a standard commercial closer?

Two things: the metal and the fasteners. The 4211 uses forged steel parallel arms and heavy gauge metal security covers rather than the cast aluminum arm and plastic or light metal cover on a standard commercial closer, and it uses Torx machine screws plus tamper-resistant regulating screws so the valves can't be backed off with a screwdriver. The body is cast iron. Standard heavy duty closers such as the BEST HD8000 or the Sargent 1431 will close the same door just as well, but nothing on them resists someone deliberately attacking the closer. If the opening is in a correctional, detention, or repeatedly vandalized area, that's what the 4211 buys you.

6) Do I have to order the 4211 handed, and can I flip it in the field?

Handing is a required selection on the 4211, left hand or right hand, so you need to know which way the door swings before you order. Take the handing from the push side, since this closer mounts parallel arm on the push face. Don't assume you can swap it on site the way you would with a non-handed tri-mount closer.

7) The LCN 4211 mounts parallel arm on the push side - what closer do I use if the door has to be closed from the pull side?

The LCN 4211 mounts surface parallel arm on the push side. For a pull side installation, the Corbin Russwin DC5230 Series is a Grade 1 surface closer with a slide track arm as standard in pull side mounting, and the Corbin Russwin DC6200 and DC8200 Series are Grade 1 surface closers with a double lever regular arm in pull side mounting. The Dorma 8916-JT is a Grade 1 heavy duty jamb track closer for frame face mounting on the pull side, adjustable size 1-6.

8) What is the closest heavy duty cast iron alternative to the LCN 4211 door closer?

The Sargent 281 Powerglide is the nearest match in construction terms - it is a cast iron surface door closer rated heavy duty and Grade 1, the same body material and duty class as the LCN 4211, which uses a high-strength cast iron cylinder and meets ANSI/BHMA A156.4 Grade 1. The Sargent 1431 Powerglide is a second heavy duty Grade 1 surface closer if the 281 sizing does not suit the opening. Where the 4211 differs is its security package: forged steel parallel arms, heavy gauge metal security covers, and tamper-resistant regulating screws intended for correctional and vandal-prone openings.

9) What door closer should I use instead of the LCN 4211 on a normal office interior door that does not need vandal resistance?

For a standard office opening with no abuse concern, a medium duty Grade 1 surface closer covers the job without the security hardware. The Sargent 1131 is a Grade 1 medium duty adjustable surface closer for medium-traffic commercial applications, and the Norton Rixson 8501A is a Grade 1 medium duty tri-mount closer with adjustable size 1-6 spring. The BEST HD7000 Series is another Grade 1 medium duty option with adjustable spring power and backcheck control. The LCN 4211 is built for correctional, institutional, and vandal-prone openings with tamper-resistant screws and metal security covers, so on a routine interior door that hardening is doing nothing for you.

10) I need a closer with one adjustable spring size that covers several door widths instead of ordering a specific size - what are my options?

The LCN 4211 is a sized closer, supplied at closer size 1. If you would rather stock one closer and dial in the spring on site, the BEST EHD9000 Series is an extra heavy-duty Grade 1 surface closer with adjustable spring sizes 1-6, and the Imperial USA TC4300 Series is a Grade 1 heavy duty ADA closer covering sizes 1-6. The Sargent 1431 Powerglide is a heavy duty Grade 1 closer with adjustable spring power. None of those carries the forged steel parallel arms and metal security covers of the 4211, so the trade is field adjustability against the high-security package.

11) Can I substitute a light duty Grade 1 closer for the LCN 4211 since both are Grade 1?

Grade 1 alone does not make them interchangeable. The Arrow DC314 and the BEST SL6000 Series are both Grade 1 but rated light duty, and the Norton Rixson 160 Series is a Grade 1 light duty light commercial closer. The LCN 4211 is heavy duty, with a cast iron cylinder, one-piece forged steel piston, and forged steel parallel arms for correctional and vandal-prone openings. On an abused door, a light duty Grade 1 closer is a different service class even though the certification line reads the same.

12) Is a Grade 2 hydraulic closer an acceptable substitute for the LCN 4211?

They are not in the same certification class. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic door closer, while the LCN 4211 meets ANSI/BHMA A156.4 Grade 1 and is UL listed for self-closing doors. If a facility spec or a fire door assembly calls for Grade 1, the Cal-Royal 500S and 700S Series are Grade 1 Cal-Royal closers, and the N900PBF is a Grade 1 barrier free hydraulic surface closer in the 900 Series. Institutional buyers writing to a Grade 1 line item should stay in that group.

13) Do I need the delay action cylinder on the LCN 4211?

Order the delay action cylinder (CYLDEL) where people need extra time to get through the opening: a healthcare corridor with carts and beds, an accessible entrance, a school door with young children. It holds the door near full open for a few seconds before the normal close cycle starts. Standard cast iron cylinder (CYL) is fine for a general traffic door. The advanced variable back check cylinder (CYLAVB) is the one to order where the door gets thrown open hard, since it slows the swing before it reaches the stop.

14) Can I open the door all the way to the wall with the 4211?

The 4211 allows a 180 degree door opening, so on a parallel arm push side application the door can swing back flat against the wall provided nothing on the opening stops it sooner. Frame conditions, hinge type, and adjacent walls are what actually limit the swing, not the closer. If you order the Cush-n-Stop arm, the arm itself sets a stopping point short of that.

15) What's the difference between LCN 4211 and 4111 closers?

Both are surface mounted heavy duty closers, but the model here is the 4211 out of the 4210 Series, configured as a high security closer with forged steel parallel arms and heavy gauge metal security covers for correctional and vandal-prone openings. When you're matching an existing installation, order by the exact model on the closer body, since arm and cover parts differ between LCN families and a mismatch means the arm won't land on the existing shoe holes.

16) I'm standardizing closers across a building. Can I use the 4211 everywhere or only on the problem doors?

Use it where it earns its keep. The 4211 is sized for interior doors to 5'0" and exterior to 4'0", so it covers most of a building's openings physically, and one finish across the job is straightforward with six powder coat colors to pick from. But the security cover and forged steel arm are aimed at correctional, institutional, and vandal-prone areas. On ordinary office and corridor doors, a heavy duty Grade 1 closer like the BEST EHD9000 or a medium duty unit like the Norton Rixson 8501A does the same closing job. A common approach is 4211 on the doors that get attacked, a standard closer everywhere else, and one finish number across both.

17) What size spring does the LCN 4211 come in, and can I adjust it?

The 4211 ships as a size 1 closer, and spring force is adjusted with LCN's Green Dial indicator so you can read where you've set it rather than counting turns. That is a different approach from the adjustable size 1-6 closers in the market, such as the BEST EHD9000 or the Sargent 1431, which spread one unit across a wide range of door sizes. Match the closer size to the door width you're hanging.

18) What is the difference between the LCN 4211 delay action cylinder and a peer closer sold as a delayed action model?

The LCN 4211 offers delay as a cylinder choice - the delay action cylinder is ordered alongside the standard cast iron cylinder and the advanced variable back check cylinder, so delay is a configuration of the same heavy duty closer. The Orca Hardware BHDC1958DA/PA and BHDC2011DA/PA are sold as delayed action models with a regular arm and parallel bracket, both listed for 1-3/4 inch doors and tri-packed with a non-hold open arm. So on the Orca side delay is the model; on the 4211 it is a cylinder selection made at order time.

19) I want a hold open closer - does the LCN 4211 do that or should I order a different model?

The LCN 4211 covers hold open through its arm selection: the hold open Cush-n-Stop arm is ordered in place of the extra duty arm or the standard Cush-n-Stop arm. If you would rather buy a closer that is a hold open model as sold, the Accentra 51 Series is an industrial closer with a tri-packed hold open arm in sizes 1-6, and the Orca Hardware BHDC1958HO/PA is a hold open closer with a parallel bracket for 1-3/4 inch doors. Neither of those brings the forged steel arms and metal security covers that make the 4211 a correctional and institutional closer.

20) What heavy duty closer can I use if I need one unit that mounts regular, parallel, or top jamb rather than parallel arm only?

The LCN 4211 is a surface parallel arm push side closer. If the job needs one closer that can go up three ways, the Dexter DCH1000 Series is a Grade 1 surface closer in tri mount - regular, parallel, or top jamb - with a full cover, and the Dexter DCH4000 Series is the same tri mount arrangement in Grade 1. The Design Hardware 116 and 416 Series are heavy duty closers supplied tri-packed with a non-hold open arm, and the 316 Series is the medium to heavy duty version. Tri-mount buys you flexibility on the frame; it does not bring the tamper-resistant screws and metal security covers of the 4211.

21) What is a lighter closer for an aluminum storefront door where the LCN 4211 is more than the opening needs?

For a storefront leaf, the Norton Rixson 1600 Series aluminum storefront closer is built for that application, Grade 1 heavy duty with tri-style mounting, and the Falcon SC61A is a Grade 1 light to medium duty cast aluminum surface closer. The Falcon SC81A is the medium duty cast aluminum version in the same family of options. The LCN 4211 is a cast iron bodied heavy duty closer sized for interior doors to 5 feet and exterior doors to 4 feet with a security cover package, which is more closer than a light storefront leaf calls for.

22) Which Falcon closer lines up with the LCN 4211 for a heavy duty opening?

The Falcon SC71A Series is the heavy duty Grade 1 surface-mount closer in the Falcon range, the same duty class and certification level as the LCN 4211. Watch the rest of the Falcon line if someone hands you a part number: the SC81A is medium duty, the SC61A is light to medium duty, and the SC91A is light duty and Grade 3. Only the SC71A sits at heavy duty. The 4211 additionally carries forged steel parallel arms, heavy gauge metal security covers, and tamper-resistant regulating screws for correctional and vandal-prone service.

23) If I am standardizing a school or healthcare campus on one Grade 1 heavy duty closer, what are the candidates alongside the LCN 4211?

The heavy duty Grade 1 surface closers in the range are the BEST EHD9000 and HD8000 Series, the Sargent 281 and 1431, the Falcon SC71A, the Dorma 8616 with flat arm and the Dorma 8916-JT jamb track, and the Norton Rixson 1600BC Series. The LCN 4211 is ADA compliant, BAA qualified, UL listed for self-closing doors, and swings to 180 degrees with all-weather fluid, which matters where the same closer has to go on both interior and exterior leaves. For the abused openings on campus - locker corridors, detention areas, entrances that take a beating - the 4211 is the one carrying tamper-resistant regulating screws and heavy gauge metal security covers.

24) A supplier offered me a Stanley Security 327 or 341 in place of the LCN 4211 - is that the same thing?

No. The Stanley Security 327 and 341 are wardrobe pivots, not door closers - the 327 is a heavy wardrobe pivot for 1-3/8 inch or 1-3/4 inch doors up to 150 pounds, and the 341 is a wardrobe pivot for flush recessed or overlay doors 1-1/8 inch to 1-3/8 inch. A pivot hangs and swings the leaf; it does nothing to close it. The LCN 4211 is a surface-mounted hydraulic closer with a cast iron cylinder that closes and controls the door, UL listed for self-closing service. If a closer is on the drawing, the pivots do not fill that line.

25) Do the closers offered without a cover replace the LCN 4211 on a door where the cover keeps getting pulled off?

They go the other direction. The Arrow DCN314 and DCN325 are Grade 1 surface closers supplied less cover with a regular or parallel arm tri-pack, adjustable spring size 1-4 on the DCN314 and 1-6 on the DCN325, and both are light duty. The LCN 4211 exists for exactly the problem you are describing: heavy gauge metal security covers and tamper-resistant regulating screws on a heavy duty cast iron body, for correctional and vandal-prone openings. If covers are being torn off, the less cover models are not the answer.

26) Will a powder coat finish hold up on an exterior door closer?

The 4211's finishes are powder coat over the cast iron body, which is a harder, thicker coating than a sprayed paint and is what LCN uses on units rated for exterior openings to 4'0". Combined with the all-weather fluid, it's built for an exterior application. Six colors are offered: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, 696 brass. On an exterior storefront, 689 and 695 are the two that usually match existing aluminum and bronze framing.

27) What tool do I need to install and adjust an LCN 4211?

Torx. The 4211 uses Torx machine screws, and the regulating screws are tamper-resistant, so a standard hex key or flat blade won't back them off. That is deliberate on a high security closer, and it means the crew doing the install and anyone adjusting sweep or latch speed later needs the right Torx driver on the truck.

28) Someone quoted me an Arrow DCN500 parallel drop plate as an accessory for a closer swap - does that work with the LCN 4211?

The Arrow DCN500DP is a parallel drop plate made for the Arrow DCN500, not a closer and not an LCN part. The LCN 4211 is assembled to order with its own arm and cylinder selections - extra duty arm, Cush-n-Stop, or hold open Cush-n-Stop - and mounts surface parallel on the push side using Torx machine screws. Order 4211 mounting components against LCN templates rather than against another manufacturer's drop plate.
