LCN 4026-REGARM-689-RH – Frequently Asked Questions

1) What size door will the LCN 4026 door closer handle?
The 4026 uses sized cylinders rated for interior doors up to 5'0" wide and exterior doors up to 4'0" wide. Spring power is adjustable using LCN's Green Dial indicator, in sizes 1-5 or a size 6 only configuration, so one closer covers a range of openings instead of forcing you to order per door width. If your exterior opening is wider than 4 feet, you are outside what this cylinder is sized for.
2) Do I have to specify handing when ordering an LCN 4026 closer?
Yes. The 4026 is ordered left hand or right hand, so determine the swing before you order. Standard practice: stand outside the opening (the push side), and if the hinges are on your left it is a left hand door.
3) Is the LCN 4026 mounted on the pull side or the push side of the door?
The 4026's mounting location is the pull side, with a top jamb (push side) surface detail also covered. It is a surface mount closer, and the mounting hole pattern is 2-1/2" x 6". Check that pattern against any existing prep before you commit, since it decides whether you reuse the holes or drill fresh.
4) Which arm should I order with an LCN 4026 closer?
Four arms are offered on the 4026: regular arm, long arm, hold open arm, and fusible link arm. Regular is the default for pull side mounting. Long arm reaches out where the frame face or reveal is deeper. Hold open lets the door stand open at a set point, which property managers want on loading and service doors. Fusible link releases the hold open when heat reaches the link, which is what you specify when a door needs to stand open but must close in a fire event.
5) Does the LCN 4026 meet ADA and Grade 1 requirements for a commercial building?
The 4026 is ADA compliant, certified to ANSI/BHMA A156.4 Grade 1, and carries UL and cUL listings. It is also BAA qualified, which matters on federally funded work with domestic sourcing requirements. That combination is what most institutional and government specs call for on a heavy traffic opening.
6) I need one closer that can be mounted regular, parallel or top jamb. Is the LCN 4026 the right pick?
No. The 4026 is ordered handed and by arm type rather than as a universal tri-pack, so it is specified for a known mounting condition. If you are stocking one part number to cover unknown openings, a tri-mount closer is the better buy: the Dexter DCH1000 Series and DCH4000 Series are Grade 1 tri-mount, the Norton Rixson 8501A is tri-mount with an adjustable size 1-6 spring, and Arrow's DCN325 ships as a regular/parallel tri-pack with size 1-6 adjustment.
7) What is the closest heavy duty cast iron equivalent to the LCN 4026 if I need a different brand on the same opening?
The Sargent 281 Powerglide is the nearest match in construction and class - it is a heavy duty Grade 1 cast iron surface door closer, the same cast iron body approach the LCN 4026 uses. Sargent's 1431 Powerglide is also a heavy duty Grade 1 surface closer with adjustable spring power if you want spring adjustment rather than a sized cylinder. Both mount on the surface of the door like the 4026, which is a heavy duty surface mounted closer with a size 6 cylinder and all-weather fluid.
8) I need a heavy duty closer with an adjustable spring size instead of the sized cylinder on the LCN 4026 - what should I look at?
The LCN 4026 uses a sized cylinder with the Green Dial spring force indicator covering spring sizes 1-5 or 6 only. If you want a field-adjustable spring range on one body, the BEST EHD9000 is an extra heavy duty Grade 1 surface closer with adjustable spring sizes 1-6, and the Imperial USA TC4300 is a Grade 1 heavy duty ADA closer in size 1-6. The Dormakaba 8916-JT is another heavy duty Grade 1 option adjustable size 1-6 with a jamb track arm and pull side frame face mounting.
9) Which closer should I use instead of the LCN 4026 if the door needs a slide track arm rather than a projecting arm?
The LCN 4026 is supplied with a regular, long, hold open, or fusible link arm. If the opening calls for a track, the Corbin Russwin DC5230 is a Grade 1 surface closer with a slide track arm standard and pull side mounting, and the Dormakaba 8916-JT is a Grade 1 heavy duty closer with a jamb track arm mounted to the frame face on the pull side. Both keep the arm tight to the door, which projecting arms do not.
10) Our spec calls for Grade 1 on every closer in the building - which alternatives to the LCN 4026 hold that grade?
The LCN 4026 is certified to ANSI/BHMA A156.4 Grade 1 with UL and cUL listings and is ADA compliant. Grade 1 peers that also meet a building-wide standardization include the BEST HD8000 heavy duty, the Corbin Russwin DC8200 and DC6200 double lever regular arm pull side closers, the Sargent 1431 heavy duty, and the Norton Rixson 1600BC aluminum storefront closer in heavy duty. The Cal-Royal 400 Series is Grade 2 and would not satisfy a Grade 1 spec.
11) Does the LCN 4026 come with a metal cover or plastic?
Either. The 4026 ships with a plastic cover as the default and a metal cover is available as an option. Cover type on the spec is listed as plastic/metal. Metal is the one to pick for schools, corrections, and other places where a cover gets kicked or pried.
12) Will an LCN 4026 hold up on an exterior door in cold weather?
It uses all-weather fluid, so closing speed stays consistent through temperature swings rather than slowing down in winter and racing in summer. The cylinder is cast iron with a full-complement bearing and a 1-1/2" diameter piston, and the body substrate is iron. Sized for exterior doors up to 4 feet wide.
13) Does the LCN 4026 have delayed action for accessible or healthcare openings?
Yes, the 4026 includes a delay function. That holds the door in the open range longer before the main closing sweep begins, which is what you want on a patient room, an accessible entry, or anywhere someone needs extra time to clear the opening with a cart or a chair.
14) How does the LCN 4026 compare to other heavy duty surface closers?
The 4026 is a heavy duty cast iron closer. Among heavy duty Grade 1 peers, the Sargent 281 Powerglide is also a cast iron body, and the Sargent 1431 Powerglide is the heavy duty aluminum alternative. BEST offers the HD8000 Series and the extra heavy duty EHD9000 Series with sizes 1-6, and Falcon's heavy duty entry is the SC71A. If the opening is lighter traffic, a medium duty closer like the Norton Rixson 8501A or the BEST HD7000 is the step down.
15) Is a tri-pack closer a drop-in replacement for the LCN 4026?
Not exactly. The LCN 4026 is ordered as left hand or right hand with a specific arm, and it is templated for pull side mounting with a 2-1/2" x 6" mounting hole pattern; top jamb push side is the alternate detail. Tri-pack closers such as the Arrow DCN325, the Accentra 2701 or the Design Hardware 116 Series ship with regular, parallel and top jamb hardware in one carton so one part covers several mounting conditions. They will close the same door, but the shoe and bracket locations are the manufacturer's own, so expect to drill a new template rather than reuse the 4026 holes.
16) What is the difference between the LCN 4026 and the Falcon SC71A?
Both are heavy duty surface mounted closers and both carry Grade 1. The LCN 4026 uses a cast iron cylinder with a 1-1/2" piston, the patented Green Dial spring indicator, all-weather fluid, and is ordered by hand with a chosen arm and powder coat finish. The Falcon SC71A is a heavy duty Grade 1 surface mount closer from the SC70A Series. If you are standardizing a building on cast iron bodies, the Falcon SC81A is the medium duty step in the same family and the SC61A is light to medium.
17) I need a hold open closer - what are my options besides the LCN 4026 hold open arm?
The LCN 4026 is available with an H hold open arm, and also with a fusible link arm for openings where the closer must release on heat. If you need hold open from another line, the Accentra 51 Series is a tri-packed hold open closer covering sizes 1-6, the Orca BHDC1958 HO is a tri-packed hold open closer for 1-3/4" doors, and the Stanley A45-501HL is a top jamb closer with a long hold open arm standard.
18) Does the LCN 4026 have delayed action, or do I need a different closer for that?
The LCN 4026 carries a delay function, so you do not need to change lines to get delayed closing on a heavy duty cast iron body. If you are comparing, the Orca BHDC1958DA and BHDC2011DA are delayed action closers with a regular arm and parallel bracket for 1-3/4" doors. The 4026 also uses all-weather fluid, which matters on the exterior side of an accessible opening where delay is usually specified.
19) Is the Arrow DC314 a substitute for the LCN 4026?
They are not in the same class. The Arrow DC314 is a Grade 1 surface mounted closer rated light duty, while the LCN 4026 is a heavy duty closer with a cast iron cylinder, full-complement bearing and 1-1/2" piston sized for interior doors to 5'0" and exterior to 4'0". On a high traffic or exterior opening the closer matching the 4026's class would be the BEST EHD9000 extra heavy duty or the Design Hardware 416 Series heavy duty, not a light duty body.
20) Which closers besides the LCN 4026 are intended for an aluminum storefront opening?
The LCN 4026 is a heavy duty cast iron surface closer available with a long arm and in powder coat finishes including 689 aluminum, which is common on storefront frames. Where the spec names a storefront-specific unit, the Norton Rixson 1600BC is a heavy duty Grade 1 aluminum storefront closer with tri-style mounting, and the Cal-Royal 700S is a Grade 1 dual valve sized closer with an adjustable tube arm often used on narrow stile frames.
21) What is a good medium duty alternative to the LCN 4026 for interior corridor doors?
The LCN 4026 is heavy duty and sized for interior doors to 5'0". On lighter interior corridor work a medium duty Grade 1 closer is usually enough: the BEST HD7000 with adjustable spring power and backcheck, the Sargent 1131 for medium traffic commercial, the Sargent 1331 with a universal aluminum body, the Norton Rixson 8501A tri-mount adjustable size 1-6, or the Dormakaba 7414 in size 1-4.
22) I need a barrier free ADA closer - how does the LCN 4026 compare to the Cal-Royal options?
The LCN 4026 is ADA compliant and heavy duty with the Green Dial indicator so the installer can set spring force to the opening force the code requires. Cal-Royal's barrier free choices are the 500S, a Grade 1 barrier free closer with adjustable back-check, and the N900PBF from the 900 Series, a Grade 1 barrier free hydraulic surface closer. Calibre's CA4001 is another Grade 1 adjustable spring tension ADA hydraulic closer.
23) What finishes does the LCN 4026 powder coat closer come in?
Six powder coat finishes: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 696 brass. Powder coat also opens up custom color matching beyond the standard range, which is the usual route when a closer has to match a storefront or a paint spec across a building.
24) Where do I find the mounting template for the LCN 4026?
LCN publishes a 4000 Series metal template data sheet and a full templates and instructions index, both available as PDFs alongside the 4026. There is also a 4000 Series surface mounted closers catalog section and a guide on choosing the right LCN closer if you are still deciding between models. Pull the template before you drill, since the hole pattern is 2-1/2" x 6".
25) Are the Stanley 327 and 341 pivots an alternative to the LCN 4026?
No. The Stanley 327 is a heavy wardrobe pivot for 1-3/8" or 1-3/4" doors up to 150 lbs and the Stanley 341 is a wardrobe pivot for flush recessed or overlay doors 1-1/8" to 1-3/8" - both hang and swing a door, they do not control its closing. The LCN 4026 is a hydraulic surface mounted closer with all-weather fluid and a delay function that regulates the closing cycle. If you are replacing a closer, stay with a closer.
26) The LCN 4026 comes with a cover - which comparable closers ship without one?
The LCN 4026 is offered with a plastic cover as standard and a metal cover option. If the specification calls for a closer less cover, the Arrow DCN314 and DCN325 are Grade 1 surface closers supplied less cover with regular and parallel arm hardware. On the other side, the Dexter DCH1000 is a Grade 1 tri-mount surface closer with a full cover, and the Design Hardware 316 Series is supplied with a cover.
