LCN 4003T-652 – Frequently Asked Questions

1) Will the LCN 4003T work on a door that swings more than 90 degrees?
No. The 4003T is built around a maximum 90 degree swing, so it belongs on openings where a wall, return, or magnet holder stops the door at 90. If the door needs to open wider, pick a closer without that limit, such as the Norton Rixson 1600 Series, which is a Grade 1 surface closer rated for 180 degree swing.
2) Is the LCN 4003T door closer approved for a fire door?
The 4003T is UL and cUL listed for self-closing doors and is intended for fire and smoke barrier door control. It is also tested to ANSI/BHMA A156.4 Grade 1 and meets ADA requirements for commercial openings.
3) Which side of the door does the LCN 4003T mount on?
Pull side, hinge (regular) surface mounting. The closer body sits on the door on the side the door pulls toward, with the arm reaching to the frame. If your opening needs the closer on the push side (parallel arm or top jamb), this is the wrong configuration; a tri-mount closer like the Dexter DCH4000 Series covers regular, parallel, and top jamb mounting from one box.
4) Do I need to specify handing when ordering the LCN 4003T closer?
The closer itself is non-handed, but the metal cover is handed and you have to pick one: MC-RH for right hand or MC-LH for left hand. Stand outside the door, on the side it swings away from, and note which side the hinges are on to get the cover right.
5) Does the LCN 4003T hold the door open?
No. There is no hold open arm and no delayed action on the 4003T; it is a straight self-closing device built to work with SEM 7850 wall magnet systems, where the magnet holds the door and releases it on alarm. If you want mechanical hold open at the arm instead, the Accentra 51 Series and the Orca BHDC1958HO are hold open arm closers. For a slow-close delay (useful on healthcare and accessible openings), the Orca BHDC1958DA is a delayed action version.
6) I have magnetic hold opens on my fire doors tied to the alarm. What closer goes with them?
The 4003T is the match for that setup. It is built for use with SEM 7850 wall magnets, where the magnet parks the door open and drops it on alarm, and the closer takes over the closing. That is also why the 90 degree swing limit is not a problem here, the magnet holder sets the open position. UL and cUL listed for self-closing doors.
7) The 4003T is size 3 - what closer covers a range of spring sizes instead of a fixed size?
The 4003T is a size 3 closer. Where one closer needs to cover several door widths across a building, adjustable spring closers are the alternative: the BEST EHD9000 is an extra heavy duty surface closer with adjustable spring sizes 1-6, the Sargent 1431 Powerglide is a heavy duty Grade 1 closer with adjustable spring power, and the Imperial USA TC4300 is a heavy duty size 1-6 ADA closer. For a narrower range, the Arrow DCN314 adjusts over spring sizes 1-4.
8) What is the closest heavy duty cast iron surface closer to an LCN 4003T from another brand?
The Sargent 281 Powerglide is the nearest match in construction terms: it is a cast iron surface door closer rated heavy duty and Grade 1, the same body material and duty class as the 4003T, which uses an iron substrate and is rated heavy duty. The Falcon SC71A is a second heavy duty Grade 1 surface closer if a cast iron body is not a requirement.
9) I need a hold open arm on the closer instead of a plain closing arm - what should I order?
The 4003T is a non-hold-open closer built to control fire and smoke barrier doors, which are required to close and latch. For an opening where hold open is wanted, the Accentra 51 Series is supplied with a tri-packed hold open arm, and the Orca BHDC1958HO carries a tri-packed hold open arm on a closer for 1-3/4 inch doors. The Stanley A45-501HL is a long hold open arm closer set up for top jamb mounting.
10) Which door closer has a delayed action feature if the LCN 4003T does not?
The 4003T has no delay function. For an opening that needs delayed closing - a healthcare corridor or an accessible entrance where someone needs extra time to clear the door - the Orca BHDC1958DA is a delayed action closer with a regular arm and parallel bracket for 1-3/4 inch doors, and the Orca BHDC2011DA is a delayed action closer in the same arm configuration.
11) What can I use on a pull side opening where a surface arm sticking out is a problem?
The 4003T mounts surface, hinge side, on the pull side with a projecting arm. Where a track is preferred on the pull side, the Corbin Russwin DC5230 is a Grade 1 surface closer with a slide track arm as standard, pull side mounting, for 1-3/4 inch doors, and the Dorma 8916-JT is a Grade 1 heavy duty jamb track closer, frame face mounting, pull side, adjustable size 1-6.
12) What closer should I use if the same unit has to work regular, parallel or top jamb depending on the door?
The 4003T is set up for surface hinge pull side mounting. When one part number has to cover regular, parallel and top jamb openings across a property, tri-mount closers do that: the Dexter DCH4000 and DCH1000 are Grade 1 surface closers listed for regular, parallel or top jamb mounting, with the DCH1000 supplied with a full cover. The Norton Rixson 8501A is a Grade 1 tri-mount closer with an adjustable size 1-6 spring, and the Arrow DCN325 ships regular and parallel arm tri-pack over spring sizes 1-6.
13) Is a Grade 2 closer acceptable where a 4003T is specified?
The 4003T is tested to ANSI/BHMA A156.4 Grade 1 and is UL and cUL listed for self-closing doors. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer, so it sits at a different certification level. If the drawing calls Grade 1 and a lighter body is wanted, the Cal-Royal 500S is a Grade 1 barrier free closer with adjustable back-check and the Cal-Royal N900PBF is a Grade 1 barrier free hydraulic surface closer.
14) What closer works on an aluminum storefront door where the 4003T is being used on hollow metal?
For aluminum storefront entrances, the Norton Rixson 1600 Series aluminum storefront closer is built for that opening with tri-style mounting, heavy duty and Grade 1. The Norton Rixson 1601P is a Grade 1 tri-mount closer with 180 degree swing, medium duty. The 4003T is designed to control fire and smoke barrier doors with a maximum swing of 90 degrees, so swing range is the detail to check against the opening.
15) We standardize on Corbin Russwin across the facility - which of their closers lines up with a 4003T?
The Corbin Russwin DC8200 Series is a Grade 1 surface closer with a double lever regular arm and pull side mounting for 1-3/4 inch doors, which matches the 4003T on pull side surface mounting and Grade 1 certification. The DC6200 Series is the same double lever regular arm pull side configuration in the DC6000 family, and the DC3200 is a Grade 1 surface closer with a regular arm.
16) Will an LCN 4003T hold up on a high traffic entry, or is it an interior closer?
The body is cast iron with a full complement bearing and a 1-1/2 inch diameter piston, and the arm is forged steel, which is the heavy duty end of surface closers. All-weather fluid keeps the sweep speed stable through temperature swings, so exposed and vestibule openings do not go slow in winter and slam in summer. It is a commercial-only device, not a residential one.
17) What finishes does the LCN 4003T plated closer come in, and what is actually plated?
Six: 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, 651 bright chrome, and 652 satin chrome. The plating goes on the metal cover, the arm, and the fasteners, so what you see on the door matches; it also adds corrosion resistance over a painted cover. 652 satin chrome is the usual match for satin stainless trim on commercial openings.
18) Does the LCN 4003T come with mounting screws or do I order them separately?
A wood and machine screw pack is included, covering size 3 or 4 mounting, so the closer, arm, and fasteners arrive together. What you do choose separately is the handed metal cover (MC-RH or MC-LH). Drop plates and special brackets are not part of the package.
19) Can I use the LCN 4003T on a federal or government job with Buy American requirements?
Yes, the 4003T is BAA qualified, which is what a government or municipal specifier looks for on a Buy American Act job. It also carries ANSI/BHMA A156.4 Grade 1 and ADA compliance, the other two boxes that usually have to be ticked on an institutional submittal.
20) Is the LCN 4003T comparable to a Sargent 281 or a Falcon SC71A?
All three are heavy duty Grade 1 surface closers, so they sit in the same class. The Sargent 281 Powerglide is likewise a cast iron body heavy duty closer, the closest construction match. The Falcon SC71A is a heavy duty Grade 1 surface closer in the SC70A Series. Where the 4003T differs is its narrower job: a fixed size 3 spring, pull side hinge mounting only, and a 90 degree swing ceiling for fire and smoke doors on magnet holders. If you want one part number covering multiple door sizes and mounting positions, the adjustable tri-mount closers are the substitution.
21) Is a light duty Grade 1 closer like the Arrow DC314 an equivalent replacement for a 4003T?
They are not the same class of closer. The Arrow DC314 is a Grade 1 surface closer rated light duty, and the Falcon SC91A is light duty at Grade 3, while the 4003T is a heavy duty closer with a cast iron cylinder and full-complement bearing built for high-traffic commercial use. Grade 1 alone does not make two closers interchangeable - the duty level is the part that tracks traffic volume.
22) What is a lighter medium duty alternative to a 4003T for an interior office door?
For interior doors that do not see entrance-level traffic, the BEST HD7000 is a medium duty Grade 1 surface closer with adjustable spring power and backcheck control, the Sargent 1131 is a Grade 1 adjustable surface closer for medium-traffic commercial use, and the Falcon SC81A is a medium duty Grade 1 cast aluminum surface closer. The 4003T is the heavy duty cast iron option in the same surface-mounted family.
23) I found a Stanley 327 pivot and a DCN500 drop plate in the closer results - do either of those replace a 4003T?
Neither is a closer. The Stanley 327 is a heavy wardrobe pivot for doors 1-3/8 inch or 1-3/4 inch up to 150 pounds, and the Stanley 341 is a wardrobe pivot for flush recessed or overlay doors - both hang a door rather than close it. The Arrow DCN500DP is a parallel drop plate for the DCN500, a mounting accessory. The 4003T is the hydraulic surface closer itself, cast iron cylinder with a 1-1/2 inch diameter piston and forged steel arm.
24) Which alternative heavy duty closer comes with a metal cover like the 4003T?
The 4003T has a metal cover, ordered right hand or left hand. Among heavy duty peers, the Design Hardware 316 Series is supplied with a cover and is rated medium to heavy duty, and the Dexter DCH1000 is a Grade 1 tri-mount surface closer with a full cover. If a cover is not wanted, the Arrow DCN314 and DCN325 are supplied less cover.
25) Is the 4003T Buy American compliant, and what else is Grade 1 for a federal job?
The 4003T is BAA qualified and tested to ANSI/BHMA A156.4 Grade 1 with UL and cUL listing for self-closing doors, which is the certification stack a government or municipal specification usually calls for. Other Grade 1 heavy duty surface closers to weigh against the spec include the BEST HD8000 Series, the Sargent 1431 Powerglide, and the Dormakaba 8616 with flat arm tri-pack.
26) Where can I get the LCN 4003T mounting template before I drill the door?
LCN publishes the templates and installation instructions index for its closers and auto operators, and the 4000 Series surface mounted closers catalog section covers the family. Pull the template for the pull side hinge mounting before laying out the door, since the 4003T is a regular arm application and the hole pattern is on the door face with the shoe on the frame stop.
