LCN 4511T-689 – Frequently Asked Questions

1) Will the LCN 4511T work on an exterior door, or is it interior only?
The 4511T is catalogued for interior door use, and the sizing bears that out: sized cylinders cover interior doors to 5'0" and exterior doors to 4'0", while the non-sized cylinder is adjustable for interior doors to 4'6" and exterior doors to 3'6". So a 3'0" exterior opening is within range, but a wide exterior door past 4'0" is beyond what this closer is sized for. The all-weather fluid means cold and heat swings will not stall it.
2) How does the LCN 4511T mount, and does it go on the push or pull side of the door?
Push side only. The 4511T mounts to the stop face on the push side of the opening as a surface-mounted closer, so the body sits on the frame stop and the arm reaches back to the door. If your opening needs a pull side closer, this is the wrong configuration to order. Corbin Russwin's DC5230 and DC6200 are pull side mounted surface closers in our line if that is the side you have to work from.
3) Do I have to specify handing when ordering an LCN 4511T?
Yes, handing is a required choice. The 4511T is ordered as either Right Hand (RH) or Left Hand (LH), so you need to know which way the door swings before the order goes in. Stand outside the opening on the push side: if the hinges are on your right, it is right hand. This is not a field-reversible unit like a tri-pack closer, so getting the hand wrong means a return.
4) Is there enough room for an LCN 4511T on a shallow frame stop?
You need 2-1/4 inches of clearance for the 4511T to mount. That number is the one to check against your frame before ordering, because the closer mounts to the stop face on the push side and the security cover adds bulk over a standard closer body. If your stop is shallower than that, a regular arm or top jamb closer mounted differently is the way to go.
5) What makes the LCN 4511T a high security closer instead of a standard commercial one?
Three things do the work: forged steel double lever arms instead of a stamped or cast arm, heavy gauge metal security covers over the body, and tamper-resistant regulating screws so nobody adjusts the sweep or latch speed without the right driver. The cover fastens with a TORX machine screw pack rather than the usual slotted or Phillips screws. That combination is what separates it from a standard heavy duty closer like the BEST HD8000 or Sargent 1431, which carry the same Grade 1 rating but no security hardware.
6) Is the LCN 4511T door closer ANSI Grade 1 and UL listed?
ANSI/BHMA A156.4 Grade 1, with UL and cUL listing for self-closing doors. It is also ADA compliant and BAA qualified, which matters if you are buying for a federal or federally funded job where domestic sourcing is written into the spec.
7) The LCN 4511T has no delay function. What closer do I use if I need delayed action or hold open?
The 4511T does not include a delay function. For a delayed action closer, the Orca Hardware BHDC1958DA/PA and BHDC2011DA/PA are delayed action closers with a regular arm and parallel bracket, both for 1-3/4 inch doors. For hold open, the Orca Hardware BHDC1958HO/PA uses a tri-packed hold open arm, the Accentra 51 Series carries a tri-packed hold open arm across sizes 1 through 6, and the Stanley Security A45-501HL is a long hold open arm standard, top jamb closer. These are conventional commercial closers rather than security closers.
8) What is the closest heavy duty Grade 1 surface closer to the LCN 4511T if I need a different brand on a correctional door?
The LCN 4511T is a heavy duty, Grade 1 surface mounted closer with a cast iron body and forged steel double lever arms, mounted stop face on the push side. The nearest heavy duty Grade 1 surface closers from other manufacturers are the BEST EHD9000 Series extra heavy-duty surface closer, the BEST HD8000 Series heavy duty surface closer, the Falcon SC71A Series heavy-duty surface closer, and the Sargent 281 Powerglide, which like the 4511T uses a cast iron body. The 4511T differs from all of them in being built specifically for vandal resistance, with heavy gauge metal security covers and tamper-resistant regulating screws driven by TORX machine screws.
9) I do not need vandal resistance, just a Grade 1 closer on an office door. What is a simpler alternative to the LCN 4511T?
The LCN 4511T carries a security cover, forged steel double lever arms and tamper-resistant regulating screws intended for correctional and vandal-prone openings. On an ordinary office door none of that is doing work. Simpler Grade 1 surface closers include the Sargent 1131, a medium duty adjustable surface closer for medium-traffic commercial applications, the Norton Rixson 1601P medium duty tri-mount closer, the BEST HD7000 Series medium duty closer with backcheck control, and the Falcon SC81A medium duty cast aluminum closer. All four are Grade 1; they trade the 4511T's cast iron body and security hardware for a lighter commercial build.
10) The LCN 4511T mounts on the push side. What Grade 1 closer should I use if the door has to be closed from the pull side?
The LCN 4511T mounts surface, stop face, on the push side of the opening. If the frame or the door swing forces a pull side installation, the Corbin Russwin DC6200 Series and DC8200 Series are Grade 1 surface closers with a double lever regular arm and pull side mounting, as is the DC5230 Series, which uses a slide track arm as standard on the pull side. The Dorma 8916-JT is a heavy duty Grade 1 jamb track closer, frame face mounted on the pull side, adjustable size 1 through 6. All four are for 1-3/4 inch doors in the Corbin Russwin case; none carry the 4511T's security cover.
11) Is a Grade 1 light duty closer like the Arrow DC314 an equivalent substitute for the LCN 4511T?
No. Both carry a Grade 1 certification, but grade and duty level are separate things. The LCN 4511T is heavy duty, built on a cast iron cylinder with a one-piece forged steel piston and double-heat-treated pinion for correctional and high traffic openings. The Arrow DC314 is a Grade 1 surface mounted closer rated light duty, as are the Arrow DCN314 and DCN325 and the BEST SL6000 Series. Matching the Grade 1 line on a spec does not put a light duty closer on the same door as the 4511T; match the duty level as well.
12) Our spec calls for ANSI Grade 1. Which closers meet it besides the LCN 4511T, and which ones do not?
The LCN 4511T is ANSI/BHMA A156.4 Grade 1 certified with UL and cUL listing for self-closing doors, and it is ADA compliant and BAA qualified. Other Grade 1 surface closers include the Corbin Russwin DC3200, the Cal-Royal 500S barrier free closer with adjustable back-check, the Cal-Royal 700S dual valve sized closer, the Dexter DCH1000 and DCM1000 Series tri-mount closers, and the Calibre CA9901 and CA4001. Two that will not satisfy a Grade 1 spec are the Cal-Royal 400 Series, a Grade 2 commercial hydraulic closer, and the Falcon SC91A, a Grade 3 light duty closer.
13) Should I use a high security closer like the LCN 4511T or a standard heavy duty closer?
Pick the 4511T when the door is in a correctional, detention, or vandal-prone setting and the closer itself is a target: forged steel arms, metal security covers and TORX tamper-resistant screws are there to stop someone defeating or stripping the unit. For a heavy traffic door where abuse is not the concern, a standard heavy duty Grade 1 closer does the same closing job for less hardware, and we carry several: the BEST EHD9000 in extra heavy duty with adjustable spring sizes 1-6, the Falcon SC71A, or the Sargent 281 cast iron closer.
14) Does the LCN 4511T have adjustable spring power, or is it a fixed size?
The 4511T is a size 1 closer. Spring force is set with LCN's Green Dial indicator so you can read where the adjustment actually sits rather than guessing by turns, but it is a sized cylinder, not a 1-6 adjustable body. If you are standardizing across a run of openings with different widths and want one part number that covers all of them, an adjustable closer suits that better: the BEST EHD9000 and the Imperial USA TC4300 both cover sizes 1-6, and the Arrow DCN314 covers 1-4.
15) What finish should I order to match the other closers in my building?
Six finishes cover the 4510T Series: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 696 brass. These are powder coat, not plated, so they hold up against handling and cleaning better than a lacquered finish. 689 aluminum is the usual institutional default and the one most likely to match closers already hanging on your other openings.
16) What tools do I need to service or adjust an LCN 4511T after it is installed?
A TORX driver. The security cover fastens with a TORX machine screw pack and the regulating screws are tamper-resistant, which is the point of the closer, but it also means your maintenance crew needs the right bit on the truck before they can touch sweep or latch speed. Budget for that if you are standardizing a facility on these.
17) The LCN 4511T is a size 1 closer. What do I order if the opening needs an adjustable spring across a range of door widths?
The 4511T is furnished at closer size 1. When one closer has to cover a range of openings, adjustable spring closers include the BEST EHD9000 Series with adjustable spring sizes 1 through 6, the Sargent 1431 Powerglide heavy duty closer with adjustable spring power, the Imperial USA TC4300 Series Grade 1 heavy duty ADA closer at sizes 1 through 6, and the Norton Rixson 8501A Grade 1 tri-mount with an adjustable size 1 through 6 spring. The Accentra 1101BF covers sizes 1 through 4 and the Accentra 2701 covers 1 through 6, both with tri-pack mounting.
18) We need a closer for an aluminum storefront entrance, not an institutional door. Does the LCN 4511T fit that job?
The 4511T is a commercial closer sized for interior doors to 5'0" and exterior doors to 4'0", intended for correctional, institutional and vandal-prone openings. For an aluminum storefront, the Norton Rixson 1600 Series aluminum storefront closer is heavy duty and Grade 1 with tri-style mounting, and the Falcon SC61A Series is a light to medium duty Grade 1 cast aluminum surface closer. Those are built around the storefront opening; the 4511T is built around security cover and forged steel arm construction.
19) Can I use one closer for regular, parallel and top jamb mounting instead of the LCN 4511T?
The 4511T is a surface mount closer set up for stop face, push side installation. If you would rather stock one closer that covers several mounting conditions, tri-mount and tri-pack closers ship with the brackets for more than one arrangement. The Dexter DCH4000 and DCL2000 Series are Grade 1 surface closers for regular, parallel or top jamb mounting, and the Dexter DCH1000 adds a full cover. The Arrow DCN325 is a Grade 1 tri-pack regular/parallel arm closer, supplied less cover, and the Dormakaba 8616 AF86P is a heavy duty Grade 1 closer with a flat non-hold open tri-pack arm.
20) Is the Stanley 327 pivot a substitute for the LCN 4511T?
No, and it is worth catching before it goes on a purchase order. The LCN 4511T is a surface mounted door closer that controls the closing of the door. The Stanley Security 327 is a heavy wardrobe pivot for doors 1-3/8" or 1-3/4" up to 150 lbs, and the Stanley 341 is a wardrobe pivot for flush recessed or overlay doors 1-1/8" to 1-3/8" thick. Pivots hang the door; they do nothing to close it. Likewise the Arrow DCN500DP is a parallel drop plate for the DCN500, a mounting accessory rather than a closer.
21) What heavy duty closers are available with a cover, similar to the security cover on the LCN 4511T?
The 4511T uses heavy gauge metal security covers held by a TORX machine screw pack, which resist tampering as well as conceal the cylinder. If the requirement is simply a covered closer on a heavy duty opening, the Design Hardware 316 Series is a medium to heavy duty closer supplied with a cover and a tri-packed non-hold open arm, and the Dexter DCH1000 Series is a Grade 1 tri-mount surface closer with a full cover. Note that the Arrow DCN314 and DCN325 are supplied less cover.
22) We standardize on one heavy duty closer across a portfolio. What are the heavy duty alternatives to the LCN 4511T if we want a single line for every door?
The LCN 4511T is heavy duty with an iron body and comes in six finishes: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze and 696 brass, in right hand or left hand. For a portfolio-wide heavy duty line, the Design Hardware 116 Series and 416 Series are heavy duty closers with tri-packed non-hold open arms, the BEST HD8000 Series is heavy duty and Grade 1, and the Sargent 1431 Powerglide is heavy duty Grade 1 with adjustable spring power. The 4511T remains the one purpose-built for vandal-prone and correctional openings, so many facilities specify it only on those doors and a general heavy duty line elsewhere.
23) How far will a door with an LCN 4511T swing open?
Up to 180 degrees, provided nothing else in the opening stops it first. Wall projection, adjacent hardware and the frame condition set the practical limit, so a door in a recessed pocket will not reach the full swing regardless of the closer. Worth confirming for corridor openings where you want the door flat against the wall.
24) Is the LCN 4511T body cast iron or aluminum?
Cast iron. The cylinder is high-strength cast iron with a one-piece forged steel piston and a double-heat-treated pinion, running on a full-complement low-friction bearing system. That is a different build from the cast aluminum closers common at this price point, such as the Falcon SC81A and SC61A, and it is why the unit stands up in detention and high abuse settings.
