LCN 4511T-652 – Frequently Asked Questions

1) Which side of the door does the LCN 4511T mount on?
Push side only. The 4511T mounts to the stop face on the push side of the opening, surface mounted, which is the arrangement that keeps the closer body out of the pull side traffic path. If the closer has to live on the pull side of your opening, this is not the configuration to order.
2) Do I have to specify handing when I order an LCN 4511T?
Yes, handing is a required choice on the 4511T. It is ordered right hand or left hand, with right hand as the default. Stand outside the opening (the push side, since that is where this closer mounts) and confirm which way the door swings before you place the order. Get it wrong and the closer will not go on the door.
3) How much clearance do I need between the door and the frame stop for an LCN 4511T?
2-1/4 inches. That is the clearance the 4511T requires for the stop face mounting on the push side. Measure the reveal on your opening before ordering, because a shallow stop or a deep frame return is what usually forces a drop plate or a different mounting style on a job like this.
4) Does the LCN 4511T meet ADA and Grade 1 for a school or hospital spec?
It does. The 4511T is ANSI/BHMA A156.4 Grade 1 certified, UL and cUL listed for self-closing doors, and meets ADA requirements. It is also BAA qualified, which matters on federally funded work. That set covers most institutional specs for a heavy duty surface closer.
5) What is the closest cross-brand equivalent to the LCN 4511T for a heavy duty Grade 1 surface closer?
The Sargent 281 Powerglide is the nearest peer in cast iron: it is a Grade 1 heavy duty surface door closer with cast iron construction, matching the 4511T's cast iron cylinder and heavy duty rating. The Falcon SC71A and BEST HD8000 are also Grade 1 heavy duty surface closers if an aluminum body is acceptable on the opening. The 4511T differs from all three in its security package - forged steel double lever arms, heavy gauge metal security covers, tamper-resistant regulating screws, and a TORX machine screw pack, which is why it is specified for correctional and vandal-prone openings.
6) Is a standard Grade 1 commercial closer enough, or does an opening need a security closer like the 4511T?
On a normal office, retail, or tenant corridor door where the closer is not being attacked, a standard Grade 1 surface closer such as the Norton Rixson 8501A or the Sargent 1431 Powerglide covers the job - both are Grade 1 surface closers, the 1431 rated heavy duty and the 8501A medium duty with an adjustable size 1-6 spring. The 4511T earns its place where the hardware itself is the target: it carries forged steel double lever arms, heavy gauge metal security covers, tamper-resistant regulating screws, and TORX machine screws so the adjustment valves and mounting cannot be reached with common tools.
7) What should be used instead of the 4511T when the door needs a hold open arm?
The 4511T is built around a non-hold-open double lever arm with security covers. When the opening calls for a mechanical hold open, the Accentra 51 Series carries a tri-packed hold open arm with adjustable spring sizes 1 through 6, and the Orca Hardware BHDC1958HO/PA is a hold open closer with a parallel bracket for 1-3/4 inch doors. Neither carries the 4511T's security cover and tamper-resistant hardware, so on a correctional or vandal-prone opening the hold open function comes at the cost of the security package.
8) The 4511T mounts on the push side - what is the alternative if the closer has to go on the pull side?
The 4511T is a surface closer mounted on the push side at the stop face. For a pull side installation, the Corbin Russwin DC6200 and DC8200 are Grade 1 surface closers with a double lever regular arm and pull side mounting for 1-3/4 inch doors, and the DC5230 is a Grade 1 pull side closer with a slide track arm standard. The Dorma 8916-JT is a Grade 1 heavy duty closer mounted frame face on the pull side. None of those carry the 4511T's security cover and TORX fastener package.
9) What is the difference between the CYL and CYLAVB cylinder options on the LCN 4511T?
Both are required choices at order time. CYL is the standard cast iron cylinder assembly and is the default. CYLAVB is the Advanced Variable Back Check cylinder, which gives you adjustable back check to stop the door being thrown into a wall or a stop. On a windy exterior opening or a corridor where people push the door hard, the AVB cylinder is the one to specify. Neither option adds delayed action, the 4511T has no delay function.
10) Can I get a 4511T with delayed action for an accessible restroom door?
No. The 4511T has no delay function. If the opening needs extra time for a wheelchair user or a cart to clear before the door starts closing, this closer will not do it and you should be looking at a closer with a delayed action valve. What the 4511T does give you is 180 degree swing and ADA compliant operation.
11) Will an LCN 4511T let the door swing a full 180 degrees?
Yes, the 4511T is rated for a 180 degree opening. That matters where you are moving beds, carts or furniture and need the leaf flat against the wall. Bear in mind it mounts push side on the stop face, so the wall condition and any adjacent hardware on the push side have to actually allow the leaf to travel that far.
12) Will an LCN 4511T hold the door open?
No. The 4511T is a self-closing unit, UL and cUL listed for self-closing doors, and no hold open arm is offered on it. If you need the door to stand open, a hold open closer such as the Accentra 51 Series (tri-packed hold open arm, sizes 1-6) or the Orca Hardware BHDC1958 hold open version is the right kind of product. Neither one is a high security closer, so you would be trading hold open for the tamper resistance the 4511T gives you.
13) What else could I use instead of an LCN 4511T for a heavy duty Grade 1 closer?
Heavy duty Grade 1 surface closers we carry include the Sargent 281 Powerglide cast iron closer, the Sargent 1431 Powerglide with adjustable spring power, the BEST EHD9000 Series (adjustable sizes 1-6), the BEST HD8000 Series, and the Falcon SC71A. The difference is that none of those is catalogued as a high security closer. The 4511T is the one with forged steel double lever arms, heavy gauge metal security covers and tamper-resistant regulating screws. If the opening is not vandal-prone, a standard heavy duty Grade 1 closer covers the job; if it is a correctional or detention corridor, the security package is the reason to stay with the 4511T.
14) Is an Arrow DCN314 or DCN325 less cover closer an alternative to the 4511T on a vandal-prone door?
No. The Arrow DCN314 and DCN325 are supplied less cover and are rated light duty; the DCN314 adjusts over spring sizes 1 through 4 and the DCN325 over 1 through 6, both with a regular or parallel arm tri-pack. Leaving the cylinder exposed is the opposite of what a vandal-prone opening needs. The 4511T carries heavy gauge metal security covers and tamper-resistant regulating screws so the valves are not reachable, and it is a heavy duty closer rather than light duty.
15) For a facility standardizing on one Grade 1 heavy duty closer across many doors, what are the alternatives to the LCN 4511T?
Within Grade 1 heavy duty surface closers, the BEST EHD9000 Series and BEST HD8000 Series, the Falcon SC71A, the Sargent 1431 and Sargent 281, the Dorma 8916-JT jamb track closer with adjustable size 1-6 spring, and the Norton Rixson 1600BC storefront closer all hold that rating. The EHD9000 and the 8916-JT adjust across spring sizes 1 through 6, which lets one model cover a range of door widths on a standardization program. The 4511T is a sized closer - size 1 - with the forged steel arms and metal security covers that the others do not carry, so a common pattern is to standardize a general closer for ordinary doors and specify the 4511T only on the secure openings.
16) Does a Grade 2 closer like the Cal-Royal 400 Series work in place of the 4511T?
Not where a Grade 1 specification governs. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer, one grade below the 4511T's ANSI/BHMA A156.4 Grade 1 certification. Within the Cal-Royal line the 500S barrier free closer with adjustable back-check, the 700S dual valve sized closer, and the N900PBF barrier free closer are Grade 1. For a correctional or institutional door the 4511T adds what none of those list: forged steel double lever arms, metal security covers, and tamper-resistant regulating screws.
17) Which closers are comparable to the 4511T for an exterior door needing all-weather operation?
The 4511T uses all-weather fluid and is sized for exterior doors to 4 feet with the sized cylinder. Among heavy duty Grade 1 peers, the Norton Rixson 1600BC is built for aluminum storefront doors with tri-style mounting, and the Falcon SC71A is a heavy duty Grade 1 surface closer. Where exterior wind load is the concern rather than vandalism, the 4511T can be ordered with the Advanced Variable Back Check cylinder to control the door on the opening swing.
18) What looks like a substitute for the 4511T in a search but is not a door closer at all?
Two Stanley Security items turn up alongside closers and are unrelated hardware: the Stanley 327 is a heavy wardrobe pivot for 1-3/8 inch or 1-3/4 inch doors up to 150 pounds, and the Stanley 341 is a wardrobe pivot for flush recessed or overlay doors 1-1/8 inch to 1-3/8 inch. Pivots carry the door; they do not close it. The Arrow DCN500DP parallel drop plate is likewise a mounting accessory for the DCN500 closer, not a closer. The 4511T is a hydraulic surface closer that controls the closing cycle.
19) Is a tri-pack closer the same thing as the 4511T for mounting flexibility?
No. Tri-pack closers such as the Dexter DCH1000 and DCH4000, the Accentra 2701, and the Calibre CA9901 ship with the brackets to mount regular, parallel, or top jamb, letting one box cover three mounting conditions. The 4511T is set up for surface mounting on the push side at the stop face and is ordered as right hand or left hand, so the handing and mounting condition are decided at order time rather than in the field.
20) Can I adjust the spring power on the 4511T after it is installed, or is it fixed?
Depends which cylinder you ordered. The 4511T is offered with a sized cylinder or a non-sized adjustable cylinder, and the adjustable one covers interior doors to 4'6" and exterior to 3'6". LCN's Green Dial spring force indicator on the closer shows you where the spring force actually sits so the adjustment is set to a real value rather than by feel. On the security side, the regulating screws are tamper-resistant, so a technician with the right tool adjusts it and a resident does not.
21) Will an LCN 4511T keep working on an exterior door through winter?
The 4511T runs all-weather hydraulic fluid with a high-efficiency full-complement low-friction bearing, so the closing speed holds up across temperature swings rather than going sluggish in the cold and fast in the heat. For exterior use, size it against the exterior limits: 4'0" with the sized cylinder, 3'6" with the non-sized.
22) What finishes does the LCN 4511T plated closer come in, and can I match the other door hardware in my building?
Six plated finishes: 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, 651 bright chrome and 652 satin chrome. Those are standard BHMA finish numbers, so matching across a facility is a matter of reading the number off the lever or exit device already on your other openings and ordering the same one. 652 satin chrome and 689 aluminum-painted are the usual institutional defaults; on this plated version, 652 is the closest match to an existing satin chrome set.
23) Do I need a special screwdriver to install or service the 4511T?
Yes. The 4511T ships with a TORX machine screw pack, and the regulating screws are tamper-resistant, so a standard Phillips will not open the security cover or touch the valves. Have the right TORX drivers on the truck before the crew goes out, because that is the detail that turns a fifteen minute closer adjustment into a second trip.
