LCN 4511-652 – Frequently Asked Questions

1) Will the LCN 4511 door closer work on a 4 foot exterior door?
Yes. The 4511 is sized for exterior doors up to 4'0" and interior doors up to 5'0" with sized cylinders. If you order the non-sized adjustable cylinder instead, the range drops to interior doors up to 4'6" and exterior doors up to 3'6", so on a full 4'0" exterior opening stay with the sized cylinder.
2) Where does the LCN 4511 mount, pull side or push side?
Pull side only. The 4511 is a surface closer mounted at the hinge on the pull side of the door, and it needs 2-1/4 inches of clearance to sit. If your opening only allows push side or top jamb mounting, this is the wrong configuration for that door.
3) Do I have to specify handing when ordering the LCN 4511 closer?
Yes, handing is a required selection. The 4511 ships right hand by default, with left hand available. Because it is a pull side hinge mounted closer, the hand has to match the door, so confirm which way the door swings from the pull side before you order.
4) What cylinder options are there on the LCN 4511 and which one do I need?
Three, and you pick one at order time. The standard cast iron cylinder assembly covers most openings. The advanced variable back check cylinder is for doors that get thrown open hard, typically exterior or wind-loaded entrances. The delay action cylinder holds the door open longer at the start of the closing cycle, which is what you want on healthcare or accessible openings where someone needs extra time to pass through.
5) Is the LCN 4511 closer suitable for a correctional or detention facility?
That is exactly what it was built for. The 4511 uses forged steel double lever arms, a heavy gauge metal security cover, and tamper-resistant regulating screws, with a TORX machine screw pack so the adjustment valves are not reachable with a common screwdriver. Cast iron cylinder body and one-piece forged steel piston back that up in vandal-prone environments.
6) Is the LCN 4511 ADA compliant and Grade 1 rated?
Both. The 4511 meets ANSI/BHMA A156.4 Grade 1 and is UL listed for self-closing doors, and it is flagged ADA compliant. It is also BAA qualified, which matters if you are buying on a federal or municipal job with domestic sourcing requirements.
7) What is the closest heavy duty Grade 1 alternative to the LCN 4511 door closer?
For a heavy duty Grade 1 surface closer in the same class, the Sargent 281 Powerglide is a cast iron surface door closer rated heavy duty and Grade 1, and the Falcon SC71A is a heavy duty Grade 1 surface-mount closer. The LCN 4511 itself is a heavy duty cast iron surface closer certified to ANSI/BHMA A156.4 Grade 1 and UL listed for self-closing doors. The difference to weigh is the security package: the 4511 adds forged steel double lever arms, a heavy gauge metal security cover, tamper-resistant regulating screws and TORX machine screws, which the Sargent and Falcon descriptions do not list.
8) Is there a cheaper standard commercial closer if vandal resistance is not required?
If the opening does not need tamper protection, a standard commercial surface closer covers it. The BEST HD7000 is a medium duty Grade 1 surface closer with adjustable spring power and backcheck, the Norton Rixson 1601P is a medium duty Grade 1 tri-mount closer with 180 degree swing, and the Sargent 1131 is a Grade 1 adjustable surface closer for medium-traffic commercial use. The LCN 4511 is built for correctional and vandal-prone environments with forged steel arms, a metal security cover and tamper-resistant regulating screws, so the medium duty units trade that security hardware for a plainer assembly.
9) The 4511 mounts on the pull side. What should I use if the closer has to go on the push side or top jamb?
The LCN 4511 is a surface hinge (pull side) closer and is mounted on the pull side of the door. For an opening that requires parallel arm or top jamb mounting, choose a tri-mount unit: the Dexter DCH4000 is a Grade 1 surface closer for regular, parallel or top jamb mounting, the Arrow DCN325 is a Grade 1 surface closer with regular and parallel arm tri-pack and adjustable spring size 1 to 6, and the Norton Rixson 8501A is a Grade 1 tri-mount closer with adjustable size 1 to 6 spring.
10) Can the LCN 4511 handle an exterior door in cold weather?
Yes. The closer is charged with all-weather fluid and runs on a full-complement low-friction bearing system, so closing speed holds up across temperature swings rather than sluggishing in winter and slamming in summer. It is listed for both exterior and interior door use.
11) Is the LCN 4511 a fixed spring size or adjustable?
The 4511 is a size 1 sized closer, not a field-adjustable 1 through 6 unit, though spring force is fine-tuned using LCN's Green Dial indicator. If your spec calls for one closer model covering a range of door widths, an adjustable unit like the BEST EHD9000 (heavy duty, Grade 1, adjustable sizes 1-6) or the Sargent 1431 Powerglide with adjustable spring power fits that approach better.
12) I need a delayed action closer. Does the 4511 do that, or should I look at another model?
The LCN 4511 offers a delay function and can be ordered with a Delay Action Cylinder in place of the standard cast iron cylinder assembly, so a separate model is not required. If a delayed action closer without the high-security construction suits the opening, the Orca Hardware BHDC1958DA/PA is a delayed action closer with a regular arm and parallel bracket for 1-3/4 inch doors, and the Orca BHDC2011DA/PA is the same delayed action arrangement in the BHDC2011 series.
13) The 4511 is a size 1 closer. What covers a wider door that needs a larger spring size?
The LCN 4511 is a size 1 closer, with sized cylinders for interior doors to 5 feet and exterior doors to 4 feet. Where a single model has to cover a range of door widths, an adjustable-size closer is the usual answer: the BEST EHD9000 is an extra heavy duty Grade 1 surface closer with adjustable spring sizes 1 to 6, the Imperial USA TC4300 is a Grade 1 heavy duty size 1 to 6 ADA closer, and the Dormakaba 8916-JT is a heavy duty Grade 1 pull side closer adjustable size 1 to 6.
14) Will a light duty Grade 1 closer work in place of the 4511 on a school corridor door?
Grade 1 alone does not make two closers interchangeable. The Arrow DC314 and the BEST SL6000 are both Grade 1 but are rated light duty, and the Falcon SC91A is light duty at Grade 3. The LCN 4511 is a heavy duty Grade 1 commercial closer built with a cast iron cylinder and forged steel arms for high-traffic and vandal-prone environments including educational facilities, so for an abused corridor door a light duty body is a step down in construction even where the grade matches.
15) What is the difference between the LCN 4511 and a Corbin Russwin DC6200 double lever pull side closer?
Both are pull side surface closers with double lever arms. The Corbin Russwin DC6200 is a Grade 1 surface closer with a double lever regular arm for pull side mounting on 1-3/4 inch doors, and the DC8200 is the same arrangement in the DC8000 series. The LCN 4511 is also a pull side surface closer with forged steel double lever arms, and adds the high-security package: a heavy gauge metal security cover, tamper-resistant regulating screws, TORX machine screws, and the Green Dial spring force indicator for setting spring power.
16) For an aluminum storefront entrance, is the 4511 the right closer?
The LCN 4511 is sized for exterior doors to 4 feet and interior doors to 5 feet and mounts on the pull side with 2-1/4 inch clearance, with its strengths aimed at correctional and vandal-prone openings. For an aluminum storefront entrance specifically, the Norton Rixson 1600 Series aluminum storefront closer is a heavy duty Grade 1 unit with tri-style mounting, and the Dormakaba 8616 is a heavy duty Grade 1 closer with a flat arm tri-pack for tight-clearance frame conditions.
17) What finishes does the LCN 4511 high security closer come in?
Six plated finishes: 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, 651 bright chrome, and 652 satin chrome. If you are standardizing a building on satin chrome trim, 652 is the usual match to existing 626 lever and exit hardware.
18) How far will a door with the LCN 4511 closer swing open?
Up to 180 degrees, provided the wall or adjacent construction allows it. That full swing is useful on institutional corridors and equipment routes where gurneys or carts have to pass.
19) Is a wardrobe pivot or a drop plate an alternative to the 4511?
No. The Stanley Security 327 and 341 are wardrobe pivots for hanging doors, not closing devices, and the Arrow DCN500DP is a parallel drop plate that serves as a mounting accessory for a DCN500 closer rather than a closer itself. The LCN 4511 is a complete surface mounted door closer with its own cylinder and arm. If you need a closer, compare it against other surface mounted closers such as the Sargent 1431 Powerglide heavy duty Grade 1 unit.
