LCN 4004T-652 – Frequently Asked Questions

1) What is the LCN 4004T door closer actually designed for?
The 4004T is a wall-pocket heavy duty closer built to work with an SEM 7850 wall magnet on fire and smoke barrier doors, with a 90 degree maximum swing. The door is held open by the wall magnet and the closer brings it shut when the magnet releases. If you need a general-purpose closer on a door that swings past 90 degrees, this is the wrong model for that opening.
2) Where does the 4004T mount on the door?
Hinge (pull) side, surface mounted. It is not a top jamb or parallel arm installation, so you need clearance and solid backing on the pull face of the door for the shoe and arm.
3) Do I have to specify handing when ordering the LCN 4004T?
Yes. The metal cover is handed, and you pick either Metal Cover Right Hand (MC-RH) or Metal Cover Left Hand (MC-LH) as a required selection. Get the hand of the door right at order time, since the cover will not read correctly on the opposite hand.
4) Is the LCN 4004T listed for use on a fire door?
Yes. It is UL and cUL listed for self-closing doors and certified to ANSI/BHMA A156.4 Grade 1, which is what an inspector looks for on a fire and smoke barrier opening. Note that hold-open on a fire door has to release on alarm, which is why this closer is paired with the SEM 7850 electromagnetic wall holder rather than a mechanical hold-open arm.
5) The LCN 4004T is a fixed size 4 closer - what should I use if I need an adjustable spring size instead?
The 4004T is supplied as closer size 4. For an adjustable-power closer, the BEST EHD9000 Series 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 Series is a heavy duty size 1-6 ADA closer. Adjustable power lets one body cover a range of door widths and weights across a building.
6) I need a hold-open closer, not the LCN 4004T with a wall magnet - what are my options?
The 4004T is built to work with an SEM 7850 wall magnet to hold the door open and release it on alarm. If you want mechanical hold open in the arm itself, the Accentra 51 Series uses a tri-packed hold open arm, and the Orca Hardware BHDC1958HO/PA is a hold open closer with a parallel bracket. Mechanical hold open is generally not acceptable on a fire or smoke barrier door, so confirm the opening before substituting.
7) The LCN 4004T is limited to 90 degrees of swing - what closer handles a wider opening?
The 4004T is engineered for 90 degrees maximum swing, which suits a wall-pocket application with a magnetic holder. Where a wider opening is needed, the Norton Rixson 1600 Series is a Grade 1 tri-mount surface closer rated for 180 degree swing. Check the wall and stop conditions at the opening before changing closers.
8) What should I order instead of the LCN 4004T if I need delayed action?
The 4004T does not include a delay function. For delayed closing, the Orca Hardware BHDC1958DA/PA and BHDC2011DA/PA are delayed action closers with a regular arm and parallel bracket. Delayed action is commonly specified for healthcare and accessible openings where occupants need more time to clear the door.
9) Is a Grade 2 closer like the Cal-Royal 400 an acceptable swap for the LCN 4004T?
No. The 4004T carries ANSI/BHMA A156.4 Grade 1 certification and is UL and cUL listed for self-closing doors, which is what a fire or smoke barrier opening requires. The Cal-Royal 400 Series is a Grade 2 commercial hydraulic closer. If you need to stay in Cal-Royal, the 500S and 700S Series are Grade 1 closers and the N900PBF is a Grade 1 barrier free surface closer.
10) Does the LCN 4004T have delayed action?
No delay function on the 4004T. For openings where you need extra time to get a cart or a wheelchair through, specify a closer with delayed action, such as the Orca Hardware BHDC1958 delayed action model.
11) Will the 4004T meet ADA opening force requirements?
The 4004T is listed as ADA compliant for accessible door operation. It is also BAA qualified, which matters on federally funded work with domestic-content requirements.
12) Is the 4004T built for an exterior door or high-traffic entrance?
Construction is heavy duty and commercial: cast iron cylinder, full-complement bearing, 1-1/2 inch diameter piston, forged steel arm, and all-weather fluid that keeps closing speed consistent through temperature swings. The all-weather fluid is what makes it suitable where temperatures vary.
13) What is the closest alternative to the LCN 4004T if I want cast iron heavy duty from another brand?
The Sargent 281 Powerglide is also a cast iron heavy duty Grade 1 surface closer, and the BEST HD8000 Series is a heavy duty Grade 1 surface closer. Neither is specified for the SEM 7850 wall magnet arrangement the 4004T is built around, so if the hold-open is an electromagnetic wall holder tied into the fire alarm, stay with the 4004T.
14) What is a lighter-duty substitute for the LCN 4004T on an interior office door?
The 4004T is a heavy duty commercial closer. For lower-traffic interior openings, the BEST HD7000 Series is a medium duty Grade 1 surface closer, the Falcon SC81A is a medium duty Grade 1 cast aluminum closer, and the BEST SL6000 Series is a light duty Grade 1 surface closer with adjustable spring sizes. These use lighter bodies than a cast iron heavy duty closer.
15) I need pull side hinge mounting like the LCN 4004T - which other closers mount that way?
The 4004T mounts surface, hinge side, on the pull side of the door. Corbin Russwin offers several pull side mounted Grade 1 surface closers: the DC5230 with a slide track arm, and the DC6200 and DC8200 with a double lever regular arm. The Dorma 8916-JT is a Grade 1 heavy duty jamb track closer for pull side frame face mounting.
16) I want one closer I can mount three ways rather than the LCN 4004T - what is available?
The 4004T is set up for surface hinge mounting on the pull side. If you want a single closer that covers regular, parallel, or top jamb mounting, the Dexter DCH1000 and DCH4000 Series are Grade 1 tri-mount surface closers, and the Arrow DCN325 is a Grade 1 surface closer with a regular/parallel arm tri-pack and adjustable spring size 1-6. Tri-mount stock is useful when a property manager is standardizing across mixed openings.
17) The LCN 4004T comes with a metal cover - which alternatives also include a cover and which are less cover?
The 4004T uses a metal cover, ordered right hand or left hand. The Dexter DCH1000 Series is a Grade 1 tri-mount surface closer supplied with a full cover, and the Design Hardware 316 Series is a heavy duty closer with cover. By contrast, the Arrow DCN314 and DCN325 are Grade 1 surface closers supplied less cover, so a cover would have to be added separately.
18) I need a closer for a light-duty interior office door, is the 4004T overkill?
Yes, for a low-traffic interior door a fixed size 4 cast iron wall-pocket closer is more than the opening needs. Lighter options include the Falcon SC91A (light duty) or the Arrow DC314 in the DC300 Series, both light duty surface closers.
19) The LCN 4004T is offered in plated finishes - which alternative closers come in painted finishes?
The 4004T plated option covers 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, 651 bright chrome, and 652 satin chrome on the metal cover, arm and fasteners. If a painted body suits the opening instead, the DORMA 7303 Series and the Dormakaba 7414 are Grade 1 medium duty closers offered in a painted finish.
