LCN 4511-689 – Frequently Asked Questions

1) Will the LCN 4511 closer work on a 4-foot wide exterior door?

Yes. The 4511 uses a sized cylinder rated for exterior doors up to 4'0" and interior doors up to 5'0". If you order the non-sized adjustable cylinder instead, the range drops to 4'6" interior and 3'6" exterior, so on a 4-foot exterior opening you want the sized version. Anything wider than 4'0" outside is past what this closer is sized for.

2) Which side of the door does the LCN 4511 mount on, and does it need handing?

Pull side, hinge-side surface mount. That is the only mounting configuration for the 4511, so it will not go on the push side or top jamb the way a tri-mount closer will. Handing is required when you order: right hand or left hand. Get the hand wrong and the closer does not go on the opening.

3) Do I need a high security door closer, or will a standard heavy duty closer do the job?

The 4511 is built for openings where people attack the hardware: correctional and detention, institutional, and vandal-prone entrances. What you pay for is forged steel double lever arms, heavy gauge metal security covers, tamper-resistant regulating screws, and Torx machine screw fasteners so the closer cannot be adjusted or pulled apart with a common screwdriver. On a normal commercial entrance with no vandalism exposure, a standard heavy duty Grade 1 closer such as the BEST HD8000 Series or the Sargent 1431 Powerglide covers the same traffic without the security hardware.

4) Is the LCN 4511 ADA compliant and Grade 1 certified?

Both. The 4511 is tested and certified to ANSI/BHMA A156.4 Grade 1 and is ADA compliant, and it is UL and cUL listed for self-closing doors with regular or fusible link arms. It is also BAA qualified, which matters if you are buying for a federal or federally funded project with domestic sourcing requirements.

5) How much clearance do I need above the door for an LCN 4511 closer?

2-1/4 inches. That is the clearance the 4511 requires, and it is the number to check against your frame head and any soffit, transom bar, or ceiling detail before you commit. Tight head conditions are the usual reason a surface closer will not go in.

6) I do not need vandal resistance, just a heavy duty Grade 1 closer for a school corridor. What else works?

The LCN 4511 is built for correctional and vandal-prone openings, and the security covers and tamper-resistant screws are the reason to pay for it. On an ordinary heavy-traffic corridor door, a straight heavy duty Grade 1 closer covers the same duty level: the BEST HD8000 Series is heavy duty and Grade 1, the BEST EHD9000 Series is extra heavy duty Grade 1 with adjustable spring sizes 1 through 6, the Sargent 1431 Powerglide is heavy duty Grade 1 with adjustable spring power, and the Falcon SC71A is a heavy duty Grade 1 surface mount closer. All are heavy duty like the 4511; none of them carry its tamper-resistant hardware.

7) The 4511 mounts on the pull side. What Grade 1 closer do I use if the door has to be closed from the push side or the frame face?

The LCN 4511 mounts surface hinge on the pull side, so it needs the hinge face of the door available. Where the pull side is not usable, a tri-mount closer gives you regular, parallel, or top jamb mounting from one part number: the Dexter DCH1000 Series is a Grade 1 surface closer, tri mount, with a full cover, and the Dexter DCH4000 Series is the same tri mount arrangement in Grade 1. The Norton Rixson 8501A is a Grade 1 tri-mount surface closer with adjustable size 1 through 6 spring, medium duty. For frame face mounting on the pull side, the Dorma 8916-JT is a Grade 1 jamb track closer, frame face mounting, pull side, heavy duty, adjustable size 1 through 6.

8) What is the closest equivalent to the LCN 4511 for a correctional door if I need double lever arm geometry from another manufacturer?

The LCN 4511 is a Grade 1 surface closer with forged steel double lever arms, mounted surface hinge on the pull side. The closest peer by arm geometry and mounting is the Corbin Russwin DC8200, a Grade 1 surface door closer with a double lever regular arm and pull side mounting, listed for 1-3/4 inch doors. The Corbin Russwin DC6200 shares the same double lever regular arm and pull side mounting in the DC6000 series, also for 1-3/4 inch doors. Both give you the double lever arm on the pull side; the 4511 adds the heavy gauge metal security covers and tamper-resistant regulating screws that the correctional application calls for.

9) Which closers look like substitutes for the LCN 4511 but are not rated for the same duty?

Several Grade 1 surface closers sit next to the LCN 4511 in a catalog but carry a lighter duty rating, and the 4511 is a heavy duty closer built for correctional and high-traffic openings. The Arrow DC314 and the BEST SL6000 Series are Grade 1 but light duty, the Falcon SC61A is Grade 1 light to medium duty, the Falcon SC81A is Grade 1 medium duty, and the Norton Rixson 1601P is Grade 1 medium duty. The Falcon SC91A is Grade 3 light duty. Grade 1 alone does not tell you the duty level, so check the duty rating as well as the grade before you swap one in on a heavy-traffic opening.

10) I need the door to stand open. Does the LCN 4511 do that, or do I need a different closer?

The LCN 4511 is a delayed action closer, which slows the door on the close cycle but still returns it to the latch. If the opening needs the door held open, that is a different arm: the Accentra 51 Series is an industrial closer with a tri-packed hold open arm in sizes 1 through 6, the Orca Hardware BHDC1958HO/PA is a hold open closer with a parallel bracket for 1-3/4 inch doors, and the Stanley Security A45-501HL is a long hold open arm, standard, top jamb. Note that a hold open arm and a delayed action closer solve different problems, so confirm which behavior the door schedule calls for before ordering.

11) Can the LCN 4511 hold a door open, and does it have delayed closing?

Delayed action is included on the 4511, so you can slow the door through the first part of its swing to let a cart, a gurney, or someone with a mobility aid clear the opening. It swings to 180 degrees. If what you actually want is a mechanical hold open arm, that is a different product: the Accentra 51 Series and the Orca BHDC1958 HO/PA are hold open arm closers.

12) Will an LCN 4511 hold up on an exterior door in cold weather?

It is filled with all-weather fluid, so the closing speed does not swing wildly between a January morning and an August afternoon the way a non-all-weather closer does. The body is high-strength cast iron with a one-piece forged steel piston and a double-heat-treated pinion, and the finish is powder coat rather than a plated finish.

13) What finishes does the LCN 4511 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. If you are matching existing closers across a building, 689 and 695 are the two that line up with most commercial aluminum and dark bronze storefront packages. Handing is specified separately from finish.

14) What is closer size 1 and is it strong enough for my door?

Size 1 is the smallest spring power in the ANSI sizing scale, matched to narrower and lighter doors rather than wide heavy entrances. On the 4511 it comes as a sized cylinder covering interior doors to 5'0" and exterior to 4'0". LCN's Green Dial spring force indicator lets the installer confirm the adjustment on site instead of guessing at the valve. If you need one closer that can be dialed across a range of door widths, an adjustable spring size 1-6 closer like the BEST EHD9000 Series or the Norton Rixson 8501A is the different tool for that job.

15) Is the LCN 4511 approved for a fire rated door?

The 4511 is UL and cUL listed for self-closing doors with regular or fusible link arms, which is the listing a self-closing fire door assembly relies on. Specify the arm type to suit the opening: a fusible link arm on a hold open application in a rated wall, a regular arm where the door must simply self-close.

16) The 4511 is a fixed size 1. What should I order if I need one closer that covers a range of door widths?

The LCN 4511 is a size 1 closer, so each opening gets the cylinder sized to it. If you would rather stock one adjustable closer across a set of openings, the BEST EHD9000 Series is a heavy duty Grade 1 closer with adjustable spring sizes 1 through 6, the Sargent 1431 Powerglide is heavy duty Grade 1 with adjustable spring power, and the Imperial USA TC4300 Series is a Grade 1 heavy duty size 1 through 6 ADA closer. For a lighter opening in the same adjustable style, the Arrow DCN325 is a Grade 1 surface closer with adjustable spring size 1 through 6. Adjustable spring closers let one part number cover several door widths; the sized 4511 is set at the factory for the opening it was specified for.

17) Is there another delayed action closer besides the LCN 4511 for an accessible opening?

The LCN 4511 is ADA compliant with a delay function and a cast iron body. If the opening needs delayed action but not the correctional-grade security hardware, 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 Hardware BHDC2011DA/PA is the same delayed action arrangement in the BHDC2011 series, also for 1-3/4 inch doors. Both use a tri-packed non-hold open arm, so the mounting can go regular or parallel, where the 4511 is set for pull side hinge mounting.

18) We are standardizing a facility on one closer. Which Grade 1 heavy duty closers should be on the short list with the LCN 4511?

The LCN 4511 is ANSI/BHMA A156.4 Grade 1, heavy duty, ADA compliant, and BAA qualified, which matters on federally funded work. Other heavy duty Grade 1 surface closers to weigh alongside it: BEST HD8000 Series and BEST EHD9000 Series, Sargent 1431 Powerglide and Sargent 281 Powerglide cast iron, Falcon SC71A, Norton Rixson 1600 Series in the 1600BC aluminum storefront version, Dormakaba 8616 with flat arm in the 8600 Series, and Dorma 8916-JT. The Sargent 281 shares the 4511's cast iron construction; the 4511 is the one in the group carrying the tamper-resistant covers and screws for correctional and vandal-prone openings.

19) The 4511 requires handing at the time of order. Which closers avoid that?

The LCN 4511 is ordered right hand or left hand, so the door swing has to be confirmed before the purchase order goes out. Tri-pack closers ship non-handed with the arm and brackets for regular, parallel, or top jamb mounting in the box: the Accentra 1101BF has a tri-packed non-hold open arm with adjustable spring sizes 1 through 4, the Accentra 2701 Series has a tri-packed non-hold open arm with adjustable spring sizes 1 through 6, and the Design Hardware 416 Series is a heavy duty closer with a tri-packed non-hold open arm. The Dexter DCL2000 and DCM1000 are Grade 1 tri mount closers as well. For a fleet order where the swings are mixed or not yet surveyed, a tri-pack removes the handing decision from the order.

20) What is the difference between the LCN 4511 and a Grade 2 closer like the Cal-Royal 400?

The LCN 4511 is certified under ANSI/BHMA A156.4 Grade 1 and rated heavy duty for commercial use. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic door closer. Grade 1 and Grade 2 are different cycle and durability tiers under the same A156.4 standard, so a facility spec calling out Grade 1 will not accept a Grade 2 closer. Within Cal-Royal, the Grade 1 options are the 500S barrier free closer with adjustable back-check, the 700S dual valve sized closer with adjustable tube arm, and the N900PBF barrier free hydraulic closer in the 900 series.

21) Can I use the LCN 4511 on an aluminum storefront door?

The LCN 4511 is a surface hinge pull side closer with a cast iron body and all-weather fluid, sized for exterior doors to 4'0" and interior doors to 5'0". Aluminum storefront usually has a narrow top rail that drives a different mounting. For that opening the Norton Rixson 1600 Series aluminum storefront closer with tri-style mounting is the purpose-built choice, heavy duty and Grade 1. The Falcon SC71A is a heavy duty Grade 1 surface mount closer as another option where the pull side hinge mounting the 4511 requires is not workable.

22) How does the LCN 4511 differ from a slide track closer like the Corbin Russwin DC5230?

The LCN 4511 uses forged steel double lever arms on the pull side, with 2-1/4 inch clearance and 180 degree opening. The Corbin Russwin DC5230 is a Grade 1 surface closer with a slide track arm standard, pull side mounting, for 1-3/4 inch doors. A slide track arm runs in a track along the door or frame instead of projecting on a lever, which changes both the template and the exposed profile. The Corbin Russwin DC3200 is another point of comparison, a Grade 1 closer with a regular arm and surface mounting for 1-3/4 inch doors. Confirm which arm style the door schedule specifies, since the arm dictates the prep.

23) What tools do I need to adjust an LCN 4511 after install?

Torx. The 4511 uses Torx machine screws and tamper-resistant regulating screws, so the sweep, latch, and backcheck valves are not accessible with a standard flat or Phillips driver. Carry the right Torx bits to the job; that is the whole point of the design, and it is also what stops a resident or an inmate from dialing the closer out of adjustment.

24) The 4511 comes with a metal security cover. What if I want a closer with no cover or a standard full cover?

The LCN 4511 carries heavy gauge metal security covers as part of its tamper resistance, finished in powder coat and available in 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 696 brass. If the opening does not need a security cover, the Arrow DCN314 and DCN325 are Grade 1 surface closers supplied less cover with regular and parallel arm tri-pack, and the Design Hardware 316 Series is a medium to heavy duty closer supplied with a cover. The Dexter DCH1000 Series is a Grade 1 tri mount closer with a full cover. A standard cover conceals the cylinder; the 4511's is the one built to resist prying and unauthorized adjustment.
