LCN 4216-693 – Frequently Asked Questions

1) Is the LCN 4216 door closer ADA compliant for opening force?

No. The 4216 is not ADA compliant. It is a high security closer built for correctional and vandal-prone openings, where spring force is set for security and door control rather than the reduced opening force an accessible opening needs. If the opening has to meet accessibility opening-force requirements, this is the wrong closer for it and you should be looking at a barrier-free model instead, such as the Cal-Royal 500S or the Calibre CA9901.

2) What size door will the LCN 4216 closer handle?

With a sized cylinder the 4216 covers interior doors to 5'0" and exterior doors to 4'0". Order it with the non-sized cylinder instead and it adjusts for interior doors to 4'6" and exterior doors to 3'6". It ships as a size 6 closer, which is the top of the standard 1 through 6 spring range and why it reaches a 5-foot interior leaf.

3) Can the LCN 4216 be mounted on the pull side of the door?

No. The 4216 mounts surface, parallel arm, on the push side only. That is deliberate on a high security closer: parallel arm puts the body and arm on the side away from the secure or public face of the opening, tucked against the frame where it is harder to attack. If your hardware schedule calls for pull side mounting or a slide track, you need a different closer, for example the Corbin Russwin DC5230, which is a slide track arm pull side unit.

4) What do I have to specify when ordering an LCN 4216 closer?

Four things are required. Handing, right hand or left hand. Cylinder, either the standard cast iron cylinder assembly (CYL) or the Advanced Variable Back Check version (CYLAVB). Arm, either the Extra Duty Arm (EDA), the Cush-n-Stop arm (CUSH), or the Hold Open Cush-n-Stop arm (HCUSH). And finish, from six powder coat options. Get the arm choice right at order time, since that decides whether the closer also acts as your door stop.

5) Do I still need a separate door stop with the LCN 4216?

Not if you order it with a Cush-n-Stop arm. Both the CUSH and the hold open HCUSH arm build a stop into the arm itself, so the closer limits the swing and takes the abuse instead of the wall or a floor stop. That matters in a correctional or vandal-prone opening where a surface-mounted wall stop is one more thing to tear off. Order the Extra Duty Arm (EDA) instead and the door swings to whatever your separate stop allows, up to 180 degrees.

6) Should I use a high security closer like the LCN 4216 or a standard heavy duty commercial closer?

Pick the 4216 when the closer itself is a target: correctional housing, detention corridors, school and institutional restrooms, anywhere covers get pried and adjustment screws get turned. It carries forged steel parallel arms, heavy gauge metal security covers, tamper-resistant regulating screws, and Torx machine screws rather than standard fasteners. For a heavy duty opening that is not vandal-prone, a conventional Grade 1 heavy duty closer does the same door control job with more mounting flexibility and lower cost of change, for instance the BEST EHD9000, the Sargent 1431 Powerglide, or the Falcon SC71A.

7) Is the LCN 4216 closer Buy American compliant for a federal project?

Yes, the 4216 is BAA qualified, which is the answer a government or municipal spec writer needs before it goes on the schedule. It is also certified to ANSI/BHMA A156.4 Grade 1 and UL listed for self-closing doors.

8) Is the LCN 4216 rated for a fire door?

The 4216 is UL listed for self-closing doors and certified to ANSI/BHMA A156.4 Grade 1. One thing to watch on the order: if the opening is a fire door, do not specify a hold open arm. The HCUSH hold open option is not appropriate on a fire rated opening, since a fire door has to close and latch on its own. Order the CUSH or EDA arm for those doors.

9) What is the closest heavy duty Grade 1 surface closer to the LCN 4216 from another brand?

The LCN 4216 is a heavy duty surface mounted closer with a cast iron cylinder, and the nearest peers by duty level and grade are the BEST HD8000 Series and the BEST EHD9000 Series, both listed as heavy duty Grade 1 surface mounted closers, and the Sargent 281, a heavy duty Grade 1 Powerglide cast iron surface closer. The Sargent 281 matches the 4216 most closely on material, since both use cast iron bodies. The Falcon SC71A Series is also a heavy duty Grade 1 surface mount closer. Where the 4216 differs from all of them is the security package: it carries forged steel parallel arms and heavy gauge metal security covers with tamper resistant regulating screws for correctional and vandal prone openings, which those peers are not described as carrying.

10) I need a closer for a standard office door, not a correctional opening. What is a simpler alternative to the LCN 4216?

The 4216 is built for correctional, vandal prone and institutional openings, so on an ordinary office door the security covers and forged steel arms are more closer than the opening needs. Medium duty Grade 1 options include the Sargent 1131, described for medium traffic commercial applications, the Norton Rixson 8501A tri-mount closer with adjustable size 1-6 spring, the BEST HD7000 Series, and the Falcon SC81A Series cast aluminum closer. For lighter interior traffic, the BEST SL6000 Series and the Norton Rixson 160 Series are light duty Grade 1 closers.

11) The 4216 mounts parallel arm on the push side. What should I use if the closer has to go on the pull side?

The LCN 4216 is a surface parallel arm closer mounted on the push side of the door. For a pull side installation, the Corbin Russwin DC5230 Series is a Grade 1 surface closer with a slide track arm 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 closer with jamb track, frame face mounting on the pull side. Note that the security cover and forged steel arm package of the 4216 does not carry over to those closers.

12) The LCN 4216 is not ADA compliant. What closer should I put on a barrier free opening instead?

The 4216 is a size 6 closer and is not ADA compliant, which rules it out where a reduced opening force is required. For barrier free openings, the Cal-Royal 500S is a Grade 1 barrier free closer with adjustable back-check and the Cal-Royal N900PBF is a Grade 1 barrier free surface closer. The Calibre CA4001 is a Grade 1 closer with adjustable spring tension for ADA use, the Calibre CA9901 is a Grade 1 tri-pack arm ADA closer in sizes 2 through 5, and the Imperial USA TC4300 Series is a heavy duty size 1-6 ADA closer if you want to stay in the heavy duty class.

13) Will the LCN 4216 work on an exterior door in cold weather?

Yes. The 4216 uses all-weather fluid, so closing speed holds steady through temperature swings instead of slowing to a crawl in winter and slamming in summer heat. It is rated for exterior doors to 4'0" with the sized cylinder. If you are chasing a door that closes fine in July and drags in January, fluid type is usually the reason.

14) Does the LCN 4216 have delayed closing for accessibility or cart traffic?

Yes, the 4216 includes a delay function, which holds the door open longer in the first part of the swing before the closer takes over. That is what you want where someone is moving a cart, a gurney, or a laundry bin through the opening. Note that the delay does not make the closer an accessible-opening product; the 4216 is not ADA compliant.

15) What is the difference between the standard cylinder and the Advanced Variable Back Check option on the LCN 4216?

Back check is what stops the door from being thrown open into the wall. The standard cast iron cylinder assembly (CYL) gives you the closer's normal back check; the Advanced Variable Back Check cylinder (CYLAVB) lets you tune where in the swing that resistance starts and how hard it bites. On a windy exterior opening or a door people shove open at speed, CYLAVB is the one to order. Either way the cylinder is high-strength cast iron with a one-piece forged steel piston.

16) Can I use the LCN 4216 to replace an existing closer on a detention or institutional door?

It depends on what is on the door now. The 4216 goes on surface, parallel arm, push side, so it drops in where a parallel arm surface closer already lives. It will not replace a pull side regular arm closer, a slide track unit, or a concealed closer without changing the mounting. Check which face the existing closer body sits on before ordering; that one detail decides the job more than any spec on the box.

17) How hard is it to tamper with or adjust an LCN 4216 after it is installed?

That is the point of the product. Heavy gauge metal security covers enclose the body, the regulating screws are tamper-resistant, and the fasteners are Torx machine screws rather than Phillips, so nobody is adjusting or pulling this closer with pocket hardware. Stock your maintenance techs with the right Torx drivers before the install, because you will need them for every service call on these.

18) What is the LCN 4216 made of and will it hold up in a high abuse opening?

Cast iron body, forged steel parallel arms, a one-piece forged steel piston, a double-heat-treated pinion, and a full-complement low-friction bearing. Iron is the substrate throughout, not aluminum, which is the real dividing line between this and most surface closers on the market. It is a commercial heavy duty unit, spec'd for correctional, institutional, and high-traffic entrances. If you want cast iron heavy duty without the security cover package, the Sargent 281 Powerglide is a cast iron heavy duty alternative.

19) What is a good alternative to the LCN 4216 if I need a heavy duty Grade 1 closer but not the security package?

Several. The BEST EHD9000 Series is an extra heavy duty Grade 1 surface closer with adjustable spring sizes 1 through 6. The BEST HD8000 Series is heavy duty Grade 1. Sargent's 1431 Powerglide and Falcon's SC71A are both heavy duty Grade 1 surface closers. Dormakaba's 8916-JT is heavy duty Grade 1 with a jamb track and adjustable size 1 to 6. What none of them carry is the 4216's forged steel arms, security covers, and tamper-resistant screws, so keep the 4216 where the closer itself gets attacked.

20) Does the LCN 4216 come handed, and does it matter which hand I order?

Yes, handing is required at order time, right hand or left hand. Stand outside the door on the side it swings away from you; if the hinges are on your right it is right hand. A parallel arm push side closer is not something you flip in the field once it shows up, so get the hand right on the purchase order. Right hand is the default if nothing is specified.

21) I am not sure yet whether the closer will mount regular, top jamb or parallel. Is there a closer that covers all three?

The LCN 4216 is specified as a surface parallel arm closer on the push side, so the mounting is fixed when you order. If you need one closer that can be set up any of the three ways in the field, the Dexter DCH1000 and DCH4000 Series, the DCL2000 and the DCM1000 are Grade 1 surface closers described as tri mount for regular, parallel or top jamb mounting, with the DCH1000 supplied with a full cover. The Arrow DCN325 is a Grade 1 surface closer with a regular and parallel arm tri-pack and adjustable spring size 1 through 6, and the Norton Rixson 1601P is a Grade 1 tri-mount closer with 180 degree swing.

22) I need the door to stay open. Does the LCN 4216 hold open, and what else does?

The 4216 can be ordered with a Hold Open Cush-n-Stop arm, which both holds the door open and stops it, alongside the non-hold-open Extra Duty Arm and Cush-n-Stop arm choices. If you are looking at other brands for hold open, the Accentra 51 Series is supplied with a tri-packed hold open arm, the Orca BHDC1958HO/PA is a hold open closer with a parallel bracket, and the Stanley A45-501HL comes with a long hold open arm standard in top jamb mounting. The Orca BHDC1958DA/PA and BHDC2011DA/PA are delayed action rather than hold open.

23) Which closers look like alternatives to the LCN 4216 but are not actually substitutes for it?

Several items sit near heavy duty closers without replacing one. The Arrow DCN500DP is a parallel drop plate for the DCN500, a mounting accessory rather than a closer. The Stanley 327 and Stanley 341 are wardrobe pivots, and the Stanley 57-0100 is a box of 100 steel machine screws for architectural hinges. Among actual closers, the Cal-Royal 400 Series is a Grade 2 hydraulic closer and the Falcon SC91A Series is a Grade 3 light duty cast aluminum closer, so neither matches the Grade 1 heavy duty specification the 4216 is built to.

24) Is there another closer with a metal cover like the LCN 4216, or do most come without one?

The 4216 carries heavy gauge metal security covers as part of its vandal resistant package, and its regulating screws are tamper resistant. Among other brands, the Dexter DCH1000 Series is a Grade 1 surface closer supplied with a full cover, and the Design Hardware 316 Series is a heavy duty closer furnished with a cover. Going the other way, the Arrow DCN314 and DCN325 are Grade 1 surface closers supplied less cover. Note that a full cover is not the same as the 4216 security cover, which is specified for vandal prone and correctional openings.

25) The LCN 4216 is a fixed size 6. What if I want to adjust spring power in the field across a run of doors?

The 4216 is a size 6 closer, and its spring force is set with the LCN Green Dial spring force indicator. If you are standardizing across doors of different widths and want one part number that covers a range, the BEST EHD9000 Series is an extra heavy duty Grade 1 closer with adjustable spring sizes 1 through 6, the Sargent 1431 Powerglide is a heavy duty Grade 1 closer with adjustable spring power, the Accentra 2701 Series covers adjustable spring sizes 1 through 6, and the Dorma 8916-JT is adjustable size 1 through 6. The Arrow DCN314 and the Accentra 1101BF cover the narrower size 1 through 4 range.

26) What is the difference between the LCN 4216 and the Sargent 281 for a high traffic entrance?

Both are heavy duty Grade 1 cast iron surface closers. The Sargent 281 is a Powerglide cast iron closer with heavy duty construction. The LCN 4216 uses a high strength cast iron cylinder with a one piece forged steel piston and double heat treated pinion, is sized for interior doors to 5 feet and exterior doors to 4 feet, runs all weather fluid, and adds forged steel parallel arms with heavy gauge metal security covers and tamper resistant regulating screws. The 4216 is fastened with Torx machine screws. If the entrance is exposed to abuse or vandalism, that security package is the deciding difference; on a protected high traffic entrance both are heavy duty Grade 1.

27) Which closers offer delayed action like the LCN 4216 for openings with slow moving traffic?

The LCN 4216 offers a delay function, which is useful in healthcare and institutional settings where people need extra time to clear the opening. Among other brands, the Orca BHDC1958DA/PA is a delayed action closer with a regular arm and parallel bracket, and the Orca BHDC2011DA/PA is a delayed action closer in the same regular arm with parallel bracket configuration; both are listed for 1-3/4 inch doors. The Orca units are tri-packed non-hold-open arm closers, so the arm arrangement differs from the forged steel parallel arm the 4216 uses.

28) I am specifying heavy duty closers for a school. Besides the LCN 4216, which heavy duty closers should I be looking at?

The 4216 is a heavy duty commercial closer specified for educational facilities among other institutional uses. Other heavy duty options include the BEST HD8000 and EHD9000 Series, both Grade 1, the Falcon SC71A Series Grade 1 heavy duty surface mount closer, the Sargent 1431 Powerglide Grade 1 heavy duty closer, the Norton Rixson 1600BC Series heavy duty Grade 1 aluminum storefront closer with tri-style mounting, and the Dormakaba 8600 Series 8616 Grade 1 heavy duty closer with a flat arm. Design Hardware 116 and 416 Series are also heavy duty closers. Where the doors take deliberate abuse, the 4216 tamper resistant construction is the point of separation.

29) What finishes does the LCN 4216 high security closer come in?

Six powder coat finishes: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 696 brass. Powder coat over the cast iron body is what lets it match a building standard across a run of openings and still take contact abuse better than a plated finish. 689 and 695 are the two that usually match existing institutional hardware.

30) How far will a door swing with the LCN 4216 installed?

Up to 180 degrees, subject to what the wall, the frame return, and any adjacent hardware allow. Order it with a Cush-n-Stop arm and the swing is limited at the arm instead, which is the usual choice on the openings this closer is built for.

31) How do I set the spring force correctly on an LCN 4216?

The 4216 carries LCN's Green Dial spring force indicator, a visual mark on the closer that shows where the spring is actually set instead of leaving you counting turns. It matters on a run of openings, since it lets you set every door in a wing to the same force and get repeatable closing across the building rather than door by door guesswork.
