LCN 4024T-652 – Frequently Asked Questions

1) Will the LCN 4024T door closer work on my 4 foot wide exterior door?

Yes. The 4024T is sized for interior doors up to 5'0" and exterior doors up to 4'0", so a 4 foot exterior leaf is at the top of its range. It is a size 4 cylinder with a 1-1/2 inch diameter piston and all-weather fluid, so it holds its closing speed through temperature swings on an exterior opening.

2) Do I have to specify handing when ordering the LCN 4024T?

Handing is required. The 4024T is ordered right hand or left hand, so you need to establish the swing before the order goes in. Stand outside the opening (the pull side here, since this closer mounts top jamb pull side) and note which side the hinges are on.

3) Which track option should I choose for the 4024T, and does it hold the door open?

Four track choices are offered and one must be selected: standard track, hold open track arm, track with bumper, and hold open track with bumper. Standard track closes the door every time. Hold open track lets housekeeping or movers park the leaf open. The bumper versions add a stop in the track to limit the swing where there is no wall stop or an adjacent wall you need to protect.

4) Is the LCN 4024T ADA compliant for a barrier free opening?

Yes, the 4024T is listed as ADA compliant, and LCN's Green Dial spring force indicator lets you set spring power without guesswork, which is what you need when an inspector is checking opening force at the door.

5) I am replacing an old LCN closer. Will the 4024T land on the existing screw holes?

The 4024T uses the LCN 4000 Series mounting hole pattern of 2-1/2" x 6". If the closer coming off the door is another 4000 Series unit mounted top jamb pull side, the pattern matches. Check the old body against that pattern before you pull it, and use the LCN 4000 Series metal template and the LCN installation templates index for the exact layout on your frame.

6) I need one closer that can be mounted regular, parallel or top jamb - is the LCN 4024T that closer?

No. The 4024T is set up for surface top jamb mounting on the pull side with a track arm. If the opening or the install crew needs mounting flexibility decided in the field, look at tri-mount closers instead: the Dexter DCH4000 and DCL2000 are Grade 1 surface closers offered tri-mount for regular, parallel or top jamb mounting, and the Norton Rixson 8501A is a Grade 1 tri-mount closer with an adjustable size 1-6 spring.

7) I need delayed action closing for an accessible or healthcare door - does the LCN 4024T do that?

The 4024T does not include a delay function. For delayed action, the Orca Hardware BHDC1958DA/PA and BHDC2011DA/PA are delayed action closers with a regular arm and parallel bracket. If hold open is what you actually need rather than delay, the 4024T is ordered with a hold open track arm, and the Orca BHDC1958HO/PA and Accentra 51 Series offer hold open arms as well.

8) Which heavy duty cast iron closers compare to the LCN 4024T for high traffic interior doors?

The Sargent 281 Powerglide is the closest in construction - a heavy duty Grade 1 cast iron surface closer, the same cast iron cylinder approach the 4024T uses. Sargent's 1431 Powerglide is also heavy duty Grade 1 with adjustable spring power, and BEST's HD8000 Series is a Grade 1 heavy duty surface closer. The 4024T differs in that it is a sized closer at size 4 rather than a field-adjustable spring range, and it runs a track arm on the pull side.

9) What is the closest cross-brand equivalent to the LCN 4024T track-arm door closer?

For a Grade 1 surface closer that also uses a track arm on the pull side, the Corbin Russwin DC5230 is the nearest peer - it is a Grade 1 surface door closer with a slide track arm standard and pull side mounting, matching the 4024T's slide-track, pull-side (top jamb) approach. The Dorma 8916-JT is another track-style option, a Grade 1 heavy duty closer with a jamb track and pull side frame face mounting. The 4024T itself is heavy duty with a cast iron cylinder, size 4, all-weather fluid and ADA compliance.

10) Will a Grade 2 closer meet the same spec as the LCN 4024T?

No. The 4024T is certified to ANSI/BHMA A156.4 Grade 1. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer and the Falcon SC91A is Grade 3, so neither satisfies a drawing calling for Grade 1. If the spec is Grade 1 and you want an alternate brand, Cal-Royal's 500S and 700S Series and the Arrow DC314 are Grade 1 surface closers.

11) Is the 4024T tough enough for a school corridor or a hospital entry?

That is the application it is built for. Heavy duty, Grade 1 under ANSI/BHMA A156.4, with a cast iron cylinder, full-complement bearing and a double heat-treated steel pinion journal. On an interior high-traffic opening in a school, hospital, retail or office building, this is the class of closer specified.

12) What plated finishes does the LCN 4024T come in, and what parts are plated?

Six plated finishes: 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, 651 bright chrome, and 652 satin chrome. The plating covers the metal cover, arm and fasteners, so the exposed hardware matches the rest of the trim on a lobby or storefront opening.

13) Can I use the LCN 4024T on a federal job with Buy American requirements?

The 4024T is BAA qualified, so it can be specified on projects carrying Buy American Act requirements. That matters on government, municipal and federally funded institutional work.

14) The 4024T is a fixed size 4. What if I want one closer I can adjust across several door widths?

The 4024T is a sized cylinder at size 4, so the spring power is matched to the door rather than dialed across a wide range. For a fleet of mixed openings where the maintenance crew wants one part number on the shelf, an adjustable spring closer is the better buy: the Accentra 51 Series covers sizes 1 through 6 with hold open, the Accentra 2701 covers 1 through 6, the Arrow DCN314 covers 1 through 4, and the Imperial USA TC4300 is a heavy duty size 1 to 6 ADA closer.

15) Is a lighter duty closer a reasonable substitute for the LCN 4024T on a low traffic interior door?

On a light-use door it can be. The Falcon SC81A is a medium duty Grade 1 cast aluminum surface closer, the Norton Rixson 1601P is a medium duty Grade 1 tri-mount closer, and the BEST SL6000 is a Grade 1 light duty surface closer with adjustable spring sizes. Those differ from the 4024T, which is specified heavy duty for commercial high-traffic openings with a cast iron cylinder, so on a high-cycle door the heavy duty unit is the one that matches the application.

16) Which closers besides the LCN 4024T come with a plated or finished metal cover?

The 4024T is supplied with a metal cover and plated finishes on cover, arm and fasteners in 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, 651 bright chrome and 652 satin chrome. Among other brands, the Dexter DCH1000 is a Grade 1 tri-mount surface closer supplied with a full cover, and the Design Hardware 316 Series is a medium to heavy duty closer offered with a cover. By contrast the Arrow DCN314 and DCN325 are supplied less cover.

17) For an aluminum storefront door, is the LCN 4024T the right closer or is there a better fit?

The 4024T is a cast iron heavy duty closer specified for commercial interior high-traffic doors to 5 feet and exterior doors to 4 feet, mounted top jamb on the pull side. For aluminum storefront work specifically, the Norton Rixson 1600BC Series is a heavy duty Grade 1 aluminum storefront closer with tri-style mounting, which gives more latitude on narrow top rails and header conditions.

18) What looks like a substitute for the LCN 4024T but is not a door closer at all?

A few Stanley Security items sit next to closers in search results but do a different job. The Stanley 327 is a heavy wardrobe pivot for doors 1-3/8 inch or 1-3/4 inch up to 150 lbs, the Stanley 341 is a wardrobe pivot for flush recessed or overlay doors 1-1/8 inch to 1-3/8 inch, and the Stanley 57-0100 is a box of 100 steel machine screws for architectural hinges. None of those control door closing. The 4024T is a hydraulic surface mounted closer with a cast iron cylinder and a track arm.
