LCN 4030-77 695 – Frequently Asked Questions

1) What exactly is the LCN 4030-77 and what does it replace?
The 4030-77 is a genuine LCN arm and forearm assembly, the two-piece linkage that connects a 4030 Series door closer body to the door or frame bracket. It is sold as a replacement part, so it is what you order when the existing arm on a 4030 closer is bent, sheared, or worn out and the closer body itself is still good. It does not include a closer body.
2) Will the 4030-77 arm fit any LCN door closer, or only the 4030 Series?
Only the 4030 Series. LCN builds this arm and forearm specifically for 4030 Series closer bodies, so the spindle broach and forearm geometry match that series. If the closer on your door is a different LCN series, the 4030-77 is the wrong part and you need the arm built for that series.
3) My closer arm is broken but the closer is an off-brand, not LCN. What arm do I need?
The 4030-77 will not work on another manufacturer's closer, since arms are matched to the closer body's spindle. Order the arm built for your series instead. If the closer is a Sargent 351 or 281, the Sargent 25-H hold-open arm covers regular and top jamb mount, and the Sargent 25-CPS and 25-CPSH are the parallel arm versions with a compression stop. For Falcon, the SC60A-3049DS is a hold-open dead stop parallel arm and the SC70A-3049/PA is a hold open arm with the PA bracket.
4) My closer body is worn out, not just the arm. Is there a complete closer I should order instead of the 4030-77?
The 4030-77 is a replacement part only, an arm and forearm for LCN 4030 Series closers, so it will not help if the body itself is failing. For a complete heavy duty Grade 1 unit, the Sargent 1431-CPS TB EN is a surface door closer supplied with a parallel arm and compression stop, and the Sargent 25-CPS is a heavy duty Grade 1 parallel arm closer with compression stop compatible with 351 and 281. Replacing the whole closer also changes the mounting prep, so verify the existing hole pattern before switching families.
5) Can a Sargent 25-H arm be used to replace the LCN 4030-77 arm and forearm assembly?
No. The LCN 4030-77 arm and forearm is built for LCN 4030 Series door closers, and the Sargent 25-H is a hold-open arm for Sargent 351 and 281 closers in standard and top jamb mount. Closer arms are matched to the pinion and shoe of their own manufacturer's body, so a Sargent arm will not land on an LCN 4030 closer. If the closer on the door is a Sargent 351 or 281, the 25-H is the arm that fits it; if the body is an LCN 4030, stay with the 4030-77.
6) What should I use if the door needs an arm that stops the door instead of a plain arm and forearm?
The LCN 4030-77 is a standard arm and forearm assembly for 4030 Series closers with no integral stop. When the opening needs the arm itself to stop the door, a compression stop parallel arm such as the Sargent 25-CPS, or the hold-open version 25-CPSH, provides that function on Sargent 351 and 281 closers. Falcon's SC60A-3049DS is a hold-open dead stop parallel arm assembly for SC60A closers. Each is tied to its own closer family, so choose by the closer body already on the door.
7) What finishes does the LCN 4030-77 arm come in so it matches the closers already on my building's doors?
Six finishes: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 696 brass. Those are standard BHMA finish numbers, so match the number stamped or specified on the existing closer covers rather than guessing by eye. Aluminum 689 and dark bronze 695 are the two you will find on most existing commercial openings.
8) Does replacing the arm keep the opening ADA compliant?
Yes. The 4030-77 assembly is ADA compliant, so a closer rebuilt with the genuine LCN arm keeps the opening force and closing behavior the original assembly was certified with. Note that ADA opening force also depends on how the closer spring and valves are adjusted, so re-check the door after the arm is installed.
9) Is this arm rated for high-traffic commercial doors or is it a light-duty part?
Commercial duty. The 4030-77 is a Grade 1 rated assembly, the heaviest BHMA grade, which is why it holds up on entrances in schools, hospitals, offices and government buildings where the door cycles constantly. It is not a residential-grade component.
10) Is the LCN 4030-77 a hold-open arm, and what do I order if I need hold-open?
The 4030-77 is a standard arm and forearm assembly for the LCN 4030 Series; hold-open is a separate arm style. On other closer families, hold-open arms include the Sargent 25-H for 351 and 281 closers and the Falcon SC70A-3049/PA, a hold-open arm supplied with a parallel arm bracket for SC70A Series closers. Match the arm to the closer body on the door rather than mixing brands.
11) Will the LCN 4030-77 work on a center hung pivoted door or an automatic operator?
No. The 4030-77 is a surface closer arm and forearm for LCN 4030 Series closers used in commercial door control. A center hung pivoted application takes a floor pivot assembly such as the Falcon OHC100A-DP, a center hung floor pivot with end load arm for OHC100 Series closers, and an automatic operator takes its own arm, such as the Falcon 8230-3077PLCM standard arm with track for 8230 Series automatic door operators. Those are different door control systems, not substitutes for a 4030 arm.
12) If I standardize on LCN 4030 arms, how does the Grade 1 rating compare to the Sargent arm options?
The LCN 4030-77 arm and forearm is a Grade 1, ADA compliant assembly for commercial use. The Sargent 25-CPS, 25-CPSH, 25-H and 1431-CPS TB EN are also listed as Grade 1, heavy duty. So the grade level is the same across them; the deciding factor is the closer family and the arm function you need, since each arm serves its own closer body.
13) Does the 4030-77 include the shoe bracket and mounting screws?
What you are buying is the arm and forearm assembly itself. It is a direct-replacement component for a 4030 Series closer, so it reuses the bracket and fasteners already on your opening. If the original shoe or bracket was damaged along with the arm, order that separately.
