LCN 4021T-652 – Frequently Asked Questions

1) What size door will the LCN 4021T door closer handle?

With sized cylinders the 4021T covers interior doors up to 5'0" wide and exterior doors up to 4'0". The non-sized cylinder version is adjustable and covers interior doors to 4'6" and exterior to 3'6". It ships as a size 1 closer, so on anything approaching the upper end of those ranges confirm the sizing matches the opening you are hanging it on.

2) Which side of the door does the LCN 4021T mount on?

Pull side, top jamb mounting. The 4021T is a surface mounted closer with the body on the pull side of the opening and a single lever arm running to a track. If your condition requires the closer body on the push side (parallel arm), this is not the mounting style you want.

3) What is the mounting hole pattern on the LCN 4021T, and will it land on my existing holes?

The closer body uses a 2-1/2" x 6" mounting hole pattern, which is the standard LCN 4000 series footprint. If you are pulling an older LCN 4000 series closer off the door and the prep is that pattern, the 4021T body drops onto the same holes. Coming off another brand, expect to drill fresh.

4) Do I have to specify handing when ordering the LCN 4021T?

Yes, handing is a required selection. You pick right hand (the default) or left hand. Stand outside the door, on the side it swings away from: if the hinges are on your right it is right hand. Getting this wrong means the arm and track are set up for the opposite swing.

5) What track options are there on the LCN 4021T and which should I pick?

Four tracks, and one must be chosen: standard track, hold open track arm, track with bumper, and hold open track with bumper. Pick hold open where staff need the door to stay open for carts or deliveries. Pick a bumper track where the door would otherwise swing into a wall or adjacent finish and you want the stop built into the track rather than adding a floor or wall stop. Hold open with bumper gives you both.

6) Is the LCN 4021T ADA compliant for an accessible opening?

Yes. The 4021T meets ADA requirements for accessible door operation, and the Green Dial spring force indicator on the closer lets the installer set and verify closing force without guesswork, which is what an inspector is checking on an accessible opening.

7) Is the LCN 4021T rated for high traffic commercial doors?

It is built for it. Cast iron cylinder, full-complement bearing, a 1-1/2 inch diameter piston and a double heat-treated steel pinion journal, rated heavy duty and certified to ANSI/BHMA A156.4 Grade 1 with UL/cUL listing. That is the construction you want on school corridors, hospital doors, and main entries where a light duty aluminum body would wear out.

8) I need delayed action on the closer - the 4021T does not have it. What are my options?

The 4021T does not include a delay function. For openings where a slow initial closing sweep is required - accessible entries, healthcare corridors, service doors - the Orca Hardware BHDC1958DA/PA is a delayed action closer with a regular arm and parallel bracket, and the Orca BHDC2011DA/PA is the same delayed action arrangement in the BHDC2011 Series. Both are listed for 1-3/4 inch doors.

9) The LCN 4021T is a fixed size 1 closer - what should I use if I need one closer that adjusts across several door widths?

The 4021T is a size 1 closer. If you want a single part number that covers a range of door widths, look at an adjustable spring size model instead: the BEST EHD9000 Series offers adjustable spring sizes 1 through 6 in a heavy duty Grade 1 body, the Sargent 1431 Powerglide is a heavy duty Grade 1 closer with adjustable spring power, the Norton Rixson 8501A is a Grade 1 tri-mount closer with adjustable size 1 through 6 spring, and the Imperial USA TC4300 is a heavy duty Grade 1 size 1 through 6 ADA closer. Adjustable models let one stocked item serve a mix of openings in a facility.

10) What is the closest heavy duty Grade 1 alternative to the LCN 4021T from another manufacturer?

The LCN 4021T is a heavy duty, Grade 1, surface mounted commercial closer with a cast iron body. The closest peers on the same duty and grade footing are the Sargent 281 Powerglide, which is also a heavy duty Grade 1 cast iron surface closer, the Sargent 1431 Powerglide heavy duty Grade 1 surface closer with adjustable spring power, and the Falcon SC71A, a heavy duty Grade 1 surface mount closer. BEST also offers the HD8000 Series and the EHD9000 Series, both heavy duty Grade 1 surface mounted closers, with the EHD9000 carrying adjustable spring sizes 1 through 6.

11) The 4021T mounts top jamb on the pull side only - what closer should I order if I need regular or parallel arm mounting too?

The 4021T is set up for surface top jamb mounting on the pull side. When the opening needs regular arm or parallel arm instead, a tri-mount closer covers all three positions from one carton: the Dexter DCH1000 and DCH4000 Series are Grade 1 surface closers offered tri mount for regular, parallel or top jamb mounting, and the Dexter DCL2000 and DCM1000 Series are the same tri mount arrangement. Norton Rixson's 1601P is a Grade 1 tri-mount surface closer as well. Arrow's DCN314 and DCN325 ship as regular/parallel arm tri-packs.

12) What other track or slide arm closers compare to the LCN 4021T rather than a standard swing arm model?

The 4021T uses a slide track arm on the pull side, which is what keeps the hardware low profile over the door. Comparable track style closers include the Corbin Russwin DC5230 Series, a Grade 1 surface closer with a slide track arm standard for pull side mounting, and the Dorma 8916-JT, a heavy duty Grade 1 jamb track closer for frame face mounting on the pull side with an adjustable size 1 through 6 spring. Standard swing arm models such as the Corbin Russwin DC6200 and DC8200 use a double lever regular arm instead.

13) Which closers look like substitutes for the LCN 4021T but are not?

Two traps. First, parts rather than closers: the Arrow DCN500DP is a parallel drop plate for the DCN500 and the Stanley Security 327 and 341 are wardrobe pivots, none of which control a door the way a hydraulic closer does. Second, arm style: several peers commonly cross-shopped against the 4021T are regular or parallel arm closers, not track closers - the Corbin Russwin DC3200 with a regular arm, the Calibre CA5501 standard arm and CA8001P parallel arm. Those change the hardware footprint on the door face and the mounting template, so confirm the arm style before substituting.

14) Will the LCN 4021T work on an exterior door in cold weather?

It uses all-weather hydraulic fluid, so closing speed stays consistent as temperatures swing, and the plated finish on the cover, arm and fasteners adds corrosion resistance. Keep exterior doors within 4'0" wide with the sized cylinder.

15) What finishes does the LCN 4021T plated closer come in to match my other door hardware?

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 codes, so if your levers and hinges are specified as 626 or 630 the closest matches here are 652 satin chrome and 646 satin nickel. The cover is metal, not plastic, so the finish carries across the whole assembly.

16) Is the LCN 4021T Buy American compliant for a federal job?

Yes, the 4021T is BAA qualified, which is what a government or municipal procurement spec usually calls for. Combined with Grade 1 certification and the UL listing, it clears the usual boxes on a federal or state facility submittal.

17) Should I use a track arm closer like the LCN 4021T or a standard regular arm closer?

A track arm keeps the arm tight to the door face and gives a cleaner, lower profile look, and the hold open and bumper functions are built into the track rather than bolted on. A conventional double lever regular arm projects further off the door but tolerates more mounting variation, and it is what you get with something like the Corbin Russwin DC6200 or DC8200. On a pull side application where appearance matters, or where you want the stop integral, the track is the better call.

18) For a school or healthcare corridor standardization, how does the LCN 4021T compare to a medium duty Grade 1 closer?

The 4021T is a heavy duty Grade 1 closer with a cast iron cylinder and is ADA compliant, which suits high-traffic corridor and entry doors. Medium duty Grade 1 peers you would weigh against it for lighter interior openings in the same facility include the Sargent 1131 for medium-traffic commercial applications, the Sargent 1331 with a universal aluminum body, the BEST HD7000 Series with adjustable spring power and backcheck control, the Norton Rixson 1601P tri-mount, and the Falcon SC81A cast aluminum closer. All carry Grade 1, so the practical split is body material and duty rating rather than certification level.

19) What is the difference between ordering the LCN 4021T with a hold open track and buying a hold open arm closer from another brand?

The 4021T is a track arm closer - hold open is selected as a track option, including a hold open track arm and a hold open track with bumper, so the hold open function lives in the slide track. Peers that offer hold open do it through the arm instead: the Accentra 51 Series uses a tri-packed hold open arm, the Orca BHDC1958HO/PA is a hold open closer with a parallel bracket, and the Stanley Security A45-501HL uses a long hold open arm mounted top jamb. Track hold open keeps the arm tight to the door face; a swing arm with hold open projects away from the door.

20) The LCN 4021T is BAA qualified - what does that narrow my alternatives to on a government job?

The 4021T is BAA qualified and ADA compliant, which is why it shows up on government and municipal specifications. When a domestic-preference clause is in play, confirm qualification on any substitute before you swap; peers in the same heavy duty Grade 1 commercial class most often evaluated alongside it are the Sargent 281 cast iron Powerglide, the Sargent 1431 Powerglide, the BEST HD8000 Series and the Falcon SC71A. Grade and duty match is only part of the test on a federally funded project - the sourcing qualification has to be verified for the specific model and finish you order.

21) Is there an alternative to the LCN 4021T for an aluminum storefront door?

The 4021T is a heavy duty Grade 1 closer with top jamb pull side mounting on a 2-1/2 inch by 6 inch hole pattern, which matters on a narrow storefront header. If you are working an aluminum storefront specifically, the Norton Rixson 1600BC Series is a heavy duty Grade 1 aluminum storefront closer with tri-style mounting. Cal-Royal's N900PBF is a Grade 1 barrier free surface closer, and the Cal-Royal 500S is a Grade 1 barrier free closer with adjustable back-check, which helps where wind catches a storefront leaf.
