LCN 4516-690 – Frequently Asked Questions

1) Will the LCN 4516 high security closer work on a 4-foot wide exterior door?

Yes. The 4516's sized cylinders cover exterior doors to 4'0" and interior doors to 5'0". If you order the non-sized cylinder instead, the range drops to 4'6" interior and 3'6" exterior, so on a 48-inch exterior opening you want the sized cylinder. Both door types are within scope for this closer.

2) How much clearance do I need to mount an LCN 4516 door closer?

2-1/4 inches. The 4516 mounts to the pull side at the hinge as a surface closer, so you need 2-1/4 inches of clear space on the pull face above the door for the body and the double lever arm. On openings where the pull side is blocked (a deep reveal, a shallow frame face), this closer will not go on as specified.

3) Do I have to specify handing when I order the LCN 4516?

Yes, handing is required. The 4516 is ordered right hand or left hand, and it's a pull side hinge mount, so the hand follows the swing of the door as you stand on the pull face. Get it wrong and the closer will not mount. Confirm the hand at the opening before the order goes in.

4) Is the LCN 4516 ADA compliant for a barrier free opening?

No. The 4516 is not ADA compliant, and it ships at closer size 6, which is a high spring power meant to control heavy correctional and institutional doors, not a reduced opening force. If you need barrier free opening force on that door, look at a barrier free closer instead, such as the Cal-Royal N900PBF or the Cal-Royal 500S.

5) What makes the LCN 4516 a high security closer instead of a standard commercial one?

Three things do the work: forged steel double lever arms, heavy gauge metal security covers, and tamper resistant regulating screws so the sweep and latch speed cannot be backed off by hand. It fastens with Torx machine screws rather than a common driver head. The body is cast iron. That package is aimed at correctional and vandal prone openings; on an ordinary office door you are paying for hardening you will not use.

6) Is the LCN 4516 door closer Buy American compliant for a federal job?

Yes, the 4516 is BAA qualified, which is the answer a government or municipal spec writer needs before it can go on a federal submittal. It's also ANSI/BHMA A156.4 Grade 1 certified and UL listed for self-closing doors.

7) I need a heavy duty Grade 1 closer but the pull side is blocked. What else can I use?

The 4516 is a pull side hinge mount only, so a blocked pull face rules it out. For a top jamb or parallel arm application, look at a tri-mount heavy duty closer instead: the Falcon SC71A Series is Grade 1 heavy duty, the Dormakaba 8616 is Grade 1 heavy duty with a tri-pack flat arm, and the Dorma 8916-JT is a Grade 1 heavy duty jamb track closer with frame face mounting. None of those carry the 4516's security hardening.

8) What is the closest heavy duty Grade 1 surface closer to the LCN 4516 if LCN is not available?

The LCN 4516 is a heavy duty Grade 1 surface mounted closer with a cast iron body, mounted on the pull side at the hinge. The closest heavy duty Grade 1 surface closers in the same class are the BEST HD8000 Series and the BEST EHD9000 Series, both listed as heavy duty Grade 1, the Sargent 281 Powerglide cast iron surface closer, listed as heavy duty Grade 1, and the Falcon SC71A Series heavy duty surface mount closer, also Grade 1. Of those, the Sargent 281 shares the cast iron body construction. None of them carry the 4516 forged steel double lever arms, heavy gauge metal security covers, or tamper resistant regulating screws, so on a correctional or vandal prone opening the security package is the deciding difference rather than the duty rating.

9) Is a standard Grade 1 commercial door closer an acceptable substitute for a high security closer on a detention or vandal prone opening?

No. Grade 1 describes cycle and durability performance, not resistance to tampering. The LCN 4516 adds forged steel double lever arms, heavy gauge metal security covers, tamper resistant regulating screws, and a TORX machine screw pack, and its cast iron body is built for correctional and vandal prone environments. Peers such as the Norton Rixson 8501A, the Sargent 1431 Powerglide, and the Dexter DCH4000 Series are Grade 1 surface closers as well, but they are general commercial closers with conventional cover and fastener arrangements. On a housing unit, holding cell, or any door where the closer itself is a target, the Grade 1 rating on the substitute does not carry the security features across.

10) What should be used instead of the LCN 4516 on an ordinary office or classroom door that does not need vandal resistance?

A medium duty Grade 1 surface closer covers that opening. The Sargent 1131 and Sargent 1331 are both medium duty Grade 1 adjustable surface closers, the BEST HD7000 Series is medium duty Grade 1 with adjustable spring power and backcheck control, the Falcon SC81A Series is a medium duty Grade 1 cast aluminum closer, and the Norton Rixson 1601P in the 1600 Series is medium duty Grade 1 with tri mount design and 180 degree swing. The LCN 4516 is built to heavy duty with a cast iron body and metal security covers, which is more closer than an interior office door with normal traffic calls for.

11) Is a light duty Grade 1 closer the same thing as the LCN 4516 because both say Grade 1?

No. Grade 1 is the certification level, and it is carried by closers built for very different traffic. The Arrow DC314 in the DC300 Series is Grade 1 but light duty, the Arrow DCN314 and DCN325 are light duty as well, the BEST SL6000 Series is light duty Grade 1, and the Norton Rixson 160 Series is a light commercial light duty Grade 1 closer. The LCN 4516 is heavy duty with a cast iron cylinder, one piece forged steel piston, and double heat treated pinion. On a high traffic institutional entrance the duty level, not the grade line on the submittal, is what has to match.

12) What closer should be selected instead of the LCN 4516 when the opening has to meet barrier free or ADA opening force?

The LCN 4516 is not ADA compliant as configured. For openings where accessible opening force governs, barrier free and ADA models are the substitutes: the Cal-Royal 500S is a Grade 1 barrier free closer with adjustable back check, the Cal-Royal N900PBF in the 900 Series is a barrier free Grade 1 hydraulic surface closer, the Calibre CA4001 is a Grade 1 adjustable spring tension ADA hydraulic closer, the Calibre CA9901 is a Grade 1 tri pack arm ADA closer in sizes 2 to 5, and the Imperial USA TC4300 Series is a Grade 1 heavy duty size 1 to 6 ADA closer. The TC4300 is the one of that group also rated heavy duty, which keeps the duty class closest to the 4516.

13) Can the LCN 4516 hold a door open, or does it have delayed action?

Delayed action, yes. The 4516 has a delay function, which lets the door stand near the open position for a few seconds before the sweep begins, useful for carts and gurneys in healthcare and institutional traffic. It's a closer, not a hold open device. If you actually need a hold open arm, that's a different product, such as the Accentra 51 Series with a tri-packed hold open arm.

14) How far will a door swing with an LCN 4516 closer on it?

180 degrees, which means the closer will not be what limits the swing. On a pull side hinge mount at 180 degrees, the door can reach the adjacent wall, so plan on a wall stop or overhead stop to take the impact. The closer's backcheck is not a stop.

15) Will an LCN 4516 hold up on an outdoor entrance in a cold climate?

It's built for it. The 4516 uses all-weather fluid, so the sweep and latch speeds hold their setting across temperature swings instead of turning slow in winter and fast in summer, and it's rated for exterior doors to 4'0". The powder coat finish is on the exterior side of the durability question too.

16) Will I need a special driver to install or adjust the LCN 4516?

Yes. The 4516 ships with a TORX machine screw pack, so the covers and mounting screws take a Torx bit, and the regulating screws are tamper resistant by design. Have the right Torx driver on the truck before the crew shows up, and expect that routine speed adjustments are deliberately not something a resident or student can do with a pocket screwdriver.

17) The LCN 4516 is a sized closer. What is the alternative if the doors on a job vary and one adjustable closer is wanted across all of them?

The 4516 uses sized cylinders, with a closer size 6 covering interior doors to 5 feet 0 inches and exterior doors to 4 feet 0 inches. Where a single adjustable body is preferred across mixed door widths, the BEST EHD9000 Series is an extra heavy duty Grade 1 closer with adjustable spring sizes 1 to 6, the Dorma 8916-JT is Grade 1 heavy duty adjustable size 1 to 6, the Imperial USA TC4300 Series is a Grade 1 heavy duty size 1 to 6 ADA closer, the Accentra 2701 Series is architectural with adjustable spring sizes 1 to 6, and the Accentra 51 Series covers size 1 to 6 with a hold open arm. Adjustable spring power lets one part number be stocked for several openings; the sized cylinder in the 4516 is set to the door it was specified for.

18) Which closer should be used instead of the LCN 4516 when the door must stand open?

The LCN 4516 is a self closing surface closer with delay function and 180 degree door opening. For an opening that needs to hold in the open position, hold open arm models are the substitute: the Accentra 51 Series is a tri packed hold open arm closer in sizes 1 to 6, the Orca Hardware BHDC1958HO/PA is a hold open closer with parallel bracket for 1-3/4 inch doors, and the Stanley Security A45-501HL uses a long hold open arm as standard in a top jamb configuration. Note that hold open should not be applied to a fire rated opening.

19) Can a Grade 2 closer be used in place of the LCN 4516 to standardize a facility on one model?

Not on the openings the 4516 is specified for. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer, one grade below the ANSI/BHMA A156.4 Grade 1 certification the 4516 carries, and the Falcon SC91A Series is Grade 3 light duty. Standardizing a correctional, healthcare, or educational facility downward means the closers on the highest traffic and highest risk doors are the ones carrying the shortfall. If one model is wanted across a building, the standardization should run to a heavy duty Grade 1 body such as the BEST HD8000 Series or the Sargent 1431 Powerglide, with the 4516 reserved for the secured openings.

20) Which closer has delayed action like the LCN 4516 if a different brand is needed for a healthcare corridor?

The LCN 4516 includes a delay function, which holds the door in the open range longer for slow moving traffic and gurney or cart passage. In another brand, the Orca Hardware BHDC1958DA/PA is a delayed action closer with regular arm and parallel bracket for 1-3/4 inch doors, and the Orca BHDC2011DA/PA is a delayed action closer in the same regular arm with parallel bracket configuration for 1-3/4 inch doors. Both are tri packed non hold open arm models, so they mount regular or parallel rather than the 4516 fixed hinge side pull configuration.

21) Is a cast aluminum body closer an equivalent swap for the LCN 4516 on an exterior institutional entrance?

The LCN 4516 uses an iron substrate with a high strength cast iron cylinder and all weather fluid, and it is rated for both interior and exterior doors. Cast aluminum bodied peers include the Falcon SC71A heavy duty Grade 1, the Falcon SC81A medium duty Grade 1, and the Sargent 1331 Grade 1 with a universal aluminum body. Among cast iron bodied peers, the Sargent 281 Powerglide is heavy duty Grade 1. On an exterior entrance that is also a vandalism target, the cast iron body plus security covers on the 4516 is a different proposition than an aluminum body closer, even at the same grade.

22) What is a simpler substitute for the LCN 4516 on a storefront or aluminum entrance door?

The LCN 4516 requires 2-1/4 inch clearance and mounts hinge side on the pull side, which an aluminum entrance with a narrow top rail may not provide. The Norton Rixson 1600 Series aluminum storefront door closer is a heavy duty Grade 1 closer with tri style mounting intended for that application, and the Norton Rixson 1601P in the 1600 Series is a Grade 1 tri mount closer with 180 degree swing, matching the 4516 on opening range. Tri mount bodies also allow the closer to move to parallel arm or top jamb if the pull side is unavailable.

23) What is the difference between the LCN 4516 and a medium duty closer with a cover when both are being quoted for the same school corridor?

The LCN 4516 is heavy duty with a cast iron body, forged steel double lever arms, and heavy gauge metal security covers, and it takes TORX machine screws so the covers and regulating screws resist tampering. 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 Dormakaba 7303 Series is a medium duty Grade 1 painted surface closer. In a school corridor the choice comes down to whether the closer will be pulled on or pried at: a decorative or standard cover keeps the closer looking finished, while the 4516 security cover and TORX fasteners are there to keep it adjusted and in place.

24) Which heavy duty closers can replace the LCN 4516 when the arm has to be a flat or low profile arm?

The LCN 4516 uses forged steel double lever arms, which project from the door face. Where a flatter arm profile is wanted, the Dormakaba 8616 AF86P FC SNB1 689 is a Grade 1 heavy duty closer with a flat arm, supplied as a flat arm non hold open tri pack, and the Dorma 8916-JT is a Grade 1 heavy duty closer with a flat non hold open arm in a jamb track, frame face pull side configuration, adjustable size 1 to 6. Both stay in the heavy duty Grade 1 class while changing the arm geometry at the door.

25) The LCN 4516 requires handing to be specified. Which comparable closers avoid that ordering step?

The 4516 is ordered right hand or left hand and mounts hinge side on the pull side, so the handing has to be confirmed at the opening before ordering. Tri pack and tri mount closers ship with the parts to go on either side of the door: the Accentra 1101BF and 2701 Series are tri packed non hold open arm models, the Arrow DCN314 and DCN325 ship as regular and parallel arm tri packs, the Design Hardware 116 and 416 Series are tri packed non hold open heavy duty closers, and the Dexter DCH1000 and DCL2000 Series are Grade 1 tri mount for regular, parallel, or top jamb. For a property manager ordering across a building with mixed handing, a tri pack removes the per door handing call.

26) What finishes does the LCN 4516 come in?

Six powder coat finishes: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, and 695 dark bronze, plus 696 brass. On a correctional or institutional retrofit, 689 aluminum and 695 dark bronze are the two that most often match existing closers already hung in the building.

27) How do I set the closing force correctly on an LCN 4516 after install?

Use the Green Dial spring force indicator. It's LCN's patented marker on the closer that shows you where the spring power is actually set instead of counting turns, so a maintenance tech can bring a door back to the same setting later. The 4516 is a size 6 closer, which is a high spring power, so on a lighter door the dial is how you confirm you have not left it cranked past what the opening needs.
