LCN 4023T-652 – Frequently Asked Questions

1) Where does the LCN 4023T door closer mount on the door and frame?

The 4023T is a surface mounted closer that goes on the pull side of the opening, top jamb mounting. The cylinder sits on the frame face above the door and the single lever arm reaches back to the door. Mounting hole pattern is 2-1/2 inches by 6 inches. If your opening needs the closer body on the door itself, or on the push side, this is not the mounting configuration you want.

2) What door width will an LCN 4023T handle?

Sized cylinders cover interior doors up to 5 feet 0 inches wide and exterior doors up to 4 feet 0 inches. The non-sized adjustable cylinder covers interior doors to 4 feet 6 inches and exterior doors to 3 feet 6 inches. The 4023T ships at closer size 3, which is the common setting for a standard 3 foot commercial door.

3) Do I have to specify handing when ordering the LCN 4023T?

Yes, handing is a required selection. The 4023T is ordered either right hand or left hand. Stand outside the opening on the side the door swings away from you: if the hinges are on the right it is right hand. Get this wrong and the arm geometry will not suit the swing.

4) Can I get the LCN 4023T with a hold open function?

Yes. Track selection is part of the order, and there are four choices: standard track, hold open track arm, track with bumper, and hold open track with bumper. Pick one of the hold open tracks if you want the door to stay open at a set point. The bumper versions add a stop in the track to limit the swing where a wall or adjacent fixture is in the way. Note that hold open on a fire rated opening has to be handled per code for that opening.

5) Is the LCN 4023T rated for fire doors?

The 4023T is UL and cUL listed for self-closing doors with regular or fusible link arms. It carries ANSI/BHMA A156.4 Grade 1 certification. If the opening is fire rated, the closer must be non-hold-open or use a fusible link or listed hold open arrangement, so choose the track accordingly.

6) I have an existing slide track closer on the frame. Will the LCN 4023T drop into the same holes?

The 4023T uses a 2-1/2 inch by 6 inch mounting hole pattern on the frame face. Lay that against what is drilled in your jamb before committing. If the existing unit is another LCN 4000 Series closer the pattern is the same family; if it is another brand, measure it. LCN publishes the 4000 Series metal template and a templates and instructions index that give the exact layout for the opening.

7) What is the closest heavy duty cast iron equivalent to the LCN 4023T from another manufacturer?

The Sargent 281 Powerglide is the nearest match in construction and duty class. Like the LCN 4023T, it is a heavy duty Grade 1 surface door closer with a cast iron body, and the 4023T uses a cast iron cylinder with a 1-1/2 inch diameter piston. Both are aimed at the same high-traffic commercial openings, so where a spec calls for a cast iron heavy duty surface closer, the 281 covers the same requirement.

8) I need a heavy duty closer with an adjustable spring size instead of the sized size 3 cylinder on the LCN 4023T. What should I use?

The LCN 4023T is supplied as closer size 3. If you want one closer that covers a range of door widths from stock, the BEST EHD9000 is an extra heavy-duty Grade 1 surface closer with adjustable spring sizes 1 through 6, and the Sargent 1431 Powerglide is a heavy duty Grade 1 closer with adjustable spring power. Both let the installer dial the size in the field rather than ordering a fixed cylinder.

9) The LCN 4023T is top jamb pull side only. What closer should I use if the opening needs regular or parallel arm mounting?

The 4023T mounts surface, top jamb on the pull side. For an opening where the mounting location has to change, a tri-mount closer is the better choice: the Norton Rixson 8501A is a Grade 1 tri-mount surface closer with an adjustable size 1-6 spring, and the Dexter DCH4000 is a Grade 1 surface closer that mounts regular, parallel, or top jamb. Either can be set to the condition the frame and door allow.

10) I need delayed action on a healthcare door. The LCN 4023T does not have it, so what is the alternative?

The 4023T has no delay function. Where delayed action is required so a slower user can clear the opening, 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 BHDC2011DA/PA is the delayed action version in that series with the same door thickness. Both are tri-packed non-hold open arm configurations.

11) What is a track arm closer comparable to the LCN 4023T if I am not buying LCN?

The 4023T runs a single lever arm in a track, offered as standard track, hold open track, track with bumper, or hold open track with bumper. Comparable track-style options include the Corbin Russwin DC5230, a Grade 1 surface closer with a slide track arm as standard and pull side mounting for 1-3/4 inch doors, and the Dorma 8916-JT, a Grade 1 heavy duty jamb track closer for frame face pull side mounting with an adjustable size 1-6 spring.

12) Is the LCN 4023T closer ADA compliant?

The 4023T is listed as ADA compliant. It is also BAA qualified, which matters on federally funded work with domestic sourcing requirements. Opening force still has to be verified after install, since spring adjustment on site determines the actual force at the door.

13) Will an LCN 4023T hold up in a school or hospital corridor?

That is what it is built for. The cylinder is cast iron with a 1-1/2 inch diameter piston, a double heat-treated steel pinion journal, and a full-complement bearing, rated heavy duty and commercial. All-weather fluid keeps the closing speed consistent when the building temperature swings. It is a Grade 1 device intended for interior high-traffic openings in offices, schools, healthcare, retail, and municipal buildings.

14) What finishes does the plated LCN 4023T come in, and what exactly is 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 is applied to the cover, arm, and fasteners, with a metal cover over the cylinder. If you are matching existing lever trim or exit device hardware in a lobby, pick the BHMA number that is already on those doors.

15) Does the LCN 4023T have delayed action for accessible openings?

No. Delay function is not included on the 4023T. If you need the door to pause open long enough for a wheelchair user or a cart to clear the opening, you need a closer specified with a delayed action valve. The Orca Hardware BHDC1958 delayed action closer is one we carry that is built specifically for that.

16) What is the difference between the LCN 4023T and a tri-pack closer like the Falcon SC71A?

The 4023T is a dedicated pull side top jamb closer with a single lever arm running in a track, so the arm stays tight to the frame with no projecting elbow. Tri-pack heavy duty closers such as the Falcon SC71A ship with the hardware to mount regular, parallel, or top jamb, which gives the installer flexibility when the opening condition is not known in advance. Pick the 4023T when the detail is fixed as pull side top jamb and you want the low-profile track look; pick a tri-mount when you are stocking one closer for mixed openings.

17) What else could I use instead of the LCN 4023T if I need a cast iron heavy duty closer?

For a cast iron heavy duty Grade 1 body, the Sargent 281 Powerglide is the closest peer we carry. The BEST HD8000 and the extra heavy duty BEST EHD9000 are also Grade 1 heavy duty surface closers. If the traffic is lighter than the 4023T is built for, the BEST HD7000 is medium duty Grade 1 and the Falcon SC81A is a medium duty cast aluminum closer.

18) Is the LCN 4023T suitable for an exterior entry door?

It can be, within limits. Sized cylinders handle exterior doors up to 4 feet 0 inches wide, or 3 feet 6 inches with the non-sized adjustable cylinder, and the all-weather fluid holds closing speed through temperature swings. That said, the 4023T is specified primarily for interior high-traffic conditions, and pull side top jamb mounting puts the closer outdoors on an out-swinging exterior door where it is exposed. For a wind-loaded exterior opening, a parallel arm mounting on the interior face is the usual approach.

19) How does the LCN 4023T compare with the Corbin Russwin DC8200 for a pull side commercial opening?

Both are Grade 1 surface closers mounted on the pull side. The LCN 4023T uses a single lever arm with a track and is furnished as closer size 3 with a cast iron cylinder; the Corbin Russwin DC8200 uses a double lever regular arm and is listed for 1-3/4 inch doors. The choice comes down to whether the opening is getting a track arm or a conventional double lever arm projecting from the door.

20) Is the Falcon SC91A a substitute for the LCN 4023T?

No. The LCN 4023T is a heavy duty closer built for high-traffic commercial doors, while the Falcon SC91A is a light duty Grade 3 cast aluminum surface closer. If the opening was specified for a heavy duty Grade 1 device, step up to the Falcon SC71A, which is a heavy duty Grade 1 surface-mount closer.

21) Is there a heavy duty closer with a hold open arm instead of the LCN 4023T track hold open?

The 4023T achieves hold open through its track options. If you would rather use a conventional arm, the Accentra 51 Series offers a tri-packed hold open arm in sizes 1 through 6, and the Orca BHDC1958HO/PA is a hold open closer with a parallel bracket for 1-3/4 inch doors. Both hold the door open at the arm rather than in a track.

22) What Grade 1 closers can I standardize on across a building alongside the LCN 4023T?

The 4023T is certified to ANSI/BHMA A156.4 Grade 1 and is UL and cUL listed for self-closing doors. Other Grade 1 heavy duty surface closers that carry the same grade for a mixed-opening rollout include the BEST HD8000, the Norton Rixson 1600BC aluminum storefront closer, and the Imperial USA TC4300 in sizes 1 through 6. Specifying all Grade 1 keeps the submittal consistent even when bodies differ.

23) Is the Cal-Royal 400 Series an acceptable replacement for an LCN 4023T?

Not where the opening was specified Grade 1. The LCN 4023T is certified to ANSI/BHMA A156.4 Grade 1, while the Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer. Within Cal-Royal, the 700S Series is a Grade 1 dual valve sized closer with an adjustable tube arm, and the 500S is a Grade 1 barrier free closer with adjustable back-check.

24) How is the LCN 4023T spring adjusted, and do I need special tools?

Spring force is set with LCN's patented Green Dial indicator, a visual spring force gauge on the cylinder so you can see the power setting rather than counting turns. It ships at size 3 and is adjusted on site to suit the door width and stack pressure.

25) The LCN 4023T comes with a metal cover. What if I need a closer without a cover?

The 4023T is furnished with a metal cover and a plated finish on cover, arm and fasteners. When the specification calls for a closer supplied less cover, the Arrow DCN314 and DCN325 are Grade 1 surface closers furnished less cover with a regular or parallel arm tri-pack, adjustable spring sizes 1-4 and 1-6 respectively.
