LCN 4211T-690 – Frequently Asked Questions

1) Will the LCN 4211T work on a 4-foot exterior door?
Yes. The 4211T uses sized cylinders rated for interior doors to 5'0" and exterior doors to 4'0". If you order the non-sized adjustable cylinder instead, the range drops to interior doors to 4'6" and exterior doors to 3'6", so for a full 4-foot exterior leaf stay with the sized cylinder.
2) Do I have to specify handing when ordering the LCN 4211T closer?
Yes, handing is a required selection. The 4211T is ordered right hand (RH) or left hand (LH). Stand outside the door: if the hinges are on your right it is right hand. Getting this wrong means the arm geometry will not suit the leaf.
3) What is the difference between the CYL and CYLAVB cylinder options on the 4211T?
Two cylinder assemblies are offered. The standard Cast Iron Cylinder Assembly (CYL) gives normal closing control. The Advanced Variable Back Check cylinder (CYLAVB) adds adjustable back check, which cushions the door before it reaches the stop, and that is what you want on wind-exposed openings or anywhere users throw the door open hard. One of the two must be chosen at order.
4) Is the LCN 4211T a good choice for a jail, detention, or high-vandalism corridor?
That is exactly the application. The 4211T is a high security closer with forged steel parallel arms, heavy gauge metal security covers, tamper-resistant regulating screws, and Torx machine screw fasteners so the unit cannot be adjusted or stripped off with common tools. Cast iron cylinder body and a one-piece forged steel piston back it up.
5) Does the LCN 4211T meet ADA opening force and Grade 1 requirements?
Yes on both counts. The 4211T is listed ADA compliant and is tested to ANSI/BHMA A156.4 Grade 1, with UL and cUL listing for self-closing doors. It is also BAA qualified, which matters on federally funded work.
6) The LCN 4211T mounts on the push side. What should I use if the closer has to go on the pull side of the door?
The 4211T is a surface closer mounted to the stop face on the push side, so it is not the part for a pull side detail. For pull side mounting, the Corbin Russwin DC5230 is a Grade 1 surface closer with a slide track arm for pull side mounting, and the DC6200 and DC8200 Series are Grade 1 surface closers with a double lever regular arm for pull side mounting. The Dorma 8916-JT is a Grade 1 heavy duty jamb track closer with frame face, pull side mounting.
7) What is the closest heavy duty Grade 1 alternative to the LCN 4211T surface closer?
The LCN 4211T is a heavy duty surface mounted closer with a cast iron body and Grade 1 certification. If you need a heavy duty Grade 1 surface closer from another maker, the Sargent 281 is a heavy duty Grade 1 cast iron surface closer, and the BEST HD8000 Series and Falcon SC71A Series are also heavy duty Grade 1 surface closers. Note that the 4211T adds a tamper-resistant security cover and Torx machine screws for vandal-prone openings, which those peers are not described as carrying.
8) I need a closer for a light-traffic interior office door, not a correctional door. What is a simpler option than the LCN 4211T?
The LCN 4211T is built for correctional and vandal-prone work, with heavy duty construction and a tamper-resistant security cover. For an ordinary low-traffic interior door, lighter surface closers include the BEST SL6000 Series and Norton Rixson 160 Series, both light duty Grade 1, and the Falcon SC91A Series, light duty at Grade 3. The Falcon SC81A Series and BEST HD7000 Series sit in between at medium duty Grade 1.
9) Is a closer sold less cover, like the Arrow DCN314, a substitute for the LCN 4211T?
Not for a security opening. The 4211T is specified in large part for its heavy gauge metal security cover, tamper-resistant regulating screws, and Torx machine screw fasteners. The Arrow DCN314 and DCN325 are supplied less cover, and both are light duty. A covered peer such as the Dexter DCH1000, which is a Grade 1 tri-mount closer with a full cover, is closer on appearance but the tamper-resistant screws and forged steel security construction of the 4211T are what make it a vandal-resistant closer.
10) Does the 4211T have a delayed closing or hold open feature?
No delay function on the 4211T, and it is a parallel arm closer without hold open. If a classroom or loading door needs the leaf to stand open, look at a hold-open arm model such as the Accentra 51 Series or the Orca BHDC1958HO instead.
11) How far will the door swing with the LCN 4211T installed?
Up to 180 degrees, subject to the wall and any stop in the way. Parallel arm push-side mounting is what allows the full swing without the arm projecting into the opening.
12) What is a comparable heavy duty Grade 1 surface closer if I do not need the security cover?
On a standard commercial opening with no vandalism concern, the security hardware on the 4211T is cost you do not need. Heavy duty Grade 1 alternatives include the BEST HD8000 and EHD9000 Series, the Sargent 1431 Powerglide and cast iron 281, and the Falcon SC71A. Keep the 4211T where tamper resistance is the point.
13) I need the closer to hold the door open. Will the LCN 4211T do that?
The LCN 4211T is a tamper-resistant closer built with forged steel parallel arms for security openings and is not offered with a hold open arm. When hold open is the requirement, the Accentra 51 Series and the Orca BHDC1958HO/PA are supplied with a tri-packed hold open arm, and the Stanley Security A45-501HL uses a long hold open arm with top jamb mounting.
14) The LCN 4211T has no delayed action. Which comparable closers offer a delay?
Delay Function on the LCN 4211T is listed as No. If delayed action closing is required, for example on an accessible or healthcare opening, the Orca BHDC1958DA/PA and BHDC2011DA/PA are delayed action closers with a regular arm and parallel bracket, both listed for 1-3/4 inch doors.
15) I need one closer model I can mount regular, top jamb, or parallel across a building. Is the LCN 4211T that closer?
No. The 4211T is fixed to one detail, surface mounted to the stop face on the push side, which is part of how the security cover and tamper-resistant screws work. For a single tri-mount model you can apply regular, parallel, or top jamb, the Dexter DCH1000 and DCH4000 Series are Grade 1 tri-mount surface closers, the Arrow DCN325 is a Grade 1 tri-pack regular or parallel arm closer with adjustable spring size 1 to 6, and the Norton Rixson 8501A is a Grade 1 tri-mount closer with an adjustable size 1 to 6 spring.
16) The LCN 4211T is size 1. What if I need an adjustable spring closer for a range of door widths?
Closer Size on the 4211T is 1. If you would rather stock one adjustable body across several door widths, the BEST EHD9000 Series is a heavy duty Grade 1 closer with adjustable spring sizes 1 to 6, the Imperial USA TC4300 Series is heavy duty with size 1 to 6 ADA adjustment, and the Sargent 1431 Powerglide is a heavy duty Grade 1 closer with adjustable spring power. For narrower ranges the Accentra 1101BF and Arrow DCN314 cover adjustable sizes 1 to 4.
17) My spec only calls for a Grade 2 hydraulic closer. Is the LCN 4211T more than I need?
The 4211T is certified to ANSI/BHMA A156.4 Grade 1 with UL and cUL listing for self-closing doors, above a Grade 2 requirement. If the drawing calls out Grade 2, the Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer. Within the same family, the Cal-Royal 500S and 700S are Grade 1 closers if you later need to meet a Grade 1 line item.
18) What finishes does the LCN 4211T 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 holds up better than paint on closers that get scrubbed or knocked in institutional corridors.
19) Will the LCN 4211T still close consistently in an unheated stairwell or cold entry?
It uses all-weather hydraulic fluid, so closing speed stays consistent as temperature swings rather than slowing badly in cold. Combined with the cast iron cylinder and heavy duty rating, it suits unconditioned interior spaces.
20) Can I use the LCN 4211T on a light traffic office or closet door?
You can, but it is more closer than that opening needs. The 4211T is a size 1 heavy duty commercial unit built for correctional and institutional traffic. For light duty interior work, the Arrow DC314 or Norton Rixson 160 Series are the right class of product.
21) How do I set the spring force on the LCN 4211T after it is installed?
Spring adjustment uses LCN's patented Green Dial indicator, which shows you the actual spring force setting instead of making you count turns. That matters here because the regulating screws are tamper resistant and you want to get the setting right the first time, particularly on openings that must hold to ADA opening force.
22) Is the Arrow DCN500DP drop plate an alternative to the LCN 4211T?
No. The Arrow DCN500DP is a parallel drop plate for the DCN500 closer, a mounting accessory rather than a closer. The LCN 4211T is the complete surface mounted closer itself, with a cast iron cylinder, forged steel parallel arms, and a security cover.
