LCN 4050A-3077/PA 689 – Frequently Asked Questions

1) Will the LCN 4050A-3077/PA arm work on my 4040 or 1461 closer, or only the 4050A?
The 3077/PA regular arm with PA shoe is built for LCN 4050A Series closers. Match the closer body series before ordering a replacement arm; a closer from another LCN family takes its own arm assembly, and arms are not interchangeable across closer bodies.
2) Do I need to order a left hand and right hand version of the LCN 4050A regular arm?
One part covers both. The 4050A-3077/PA arm is non-handed, so the same assembly goes on a left hand or right hand opening. For a property manager stocking spares across a building, that means one line item instead of two.
3) Is the PA shoe included with the LCN 3077/PA arm or do I order it separately?
The 62PA shoe comes with the arm. The 3077/PA is a complete assembly, so you are not buying the shoe as a separate line to finish the install.
4) I need the door to stay open on its own. Is the LCN 4050A-3077/PA the right arm?
No. The 3077/PA is a regular arm with a PA shoe and no hold-open function. For a hold-open you need an arm assembly built with it, such as the Sargent 25-H for 351 and 281 closers or the Falcon SC70A-3049/PA hold open arm on SC70A closers. On an LCN 4050A closer, specify the hold-open arm variant for that series rather than this one.
5) My closer arm is bent from someone forcing the door. Can I replace just the arm instead of the whole closer?
Yes, and that is what this part is for. The 4050A-3077/PA is a replacement arm assembly, so if the closer body still holds oil and controls sweep and latch, you swap the arm and shoe and leave the body on the door. Order it in the finish that matches the closer cover already up there.
6) What is the closest Sargent equivalent to an LCN 4050A regular arm when the closer already on the door is a Sargent 351 or 281?
The LCN 4050A-3077/PA is built for LCN 4050A Series closers, so it will not serve a Sargent closer body. For a Sargent 351 or 281 closer, the Sargent 25-H hold-open arm is the peer part, and it is set up for standard and top jamb mount. Match the arm to the closer brand and series first - a door closer arm is a body-specific assembly, not a universal fit.
7) The door has no wall stop and slams into a corner - is the 4050A regular arm the right choice?
The LCN 4050A-3077/PA is a regular arm assembly with PA shoe; it controls the swing but is not a stop arm. When the opening needs the arm itself to stop the door, the Falcon SC60A-3049DS is a hold-open dead stop parallel arm assembly, and the Sargent 25-CPS is a heavy duty parallel arm with compression stop. Each fits its own closer line, so confirm the closer body before ordering.
8) What is the difference between a regular arm and a parallel arm on an LCN 4050A closer?
A regular arm mounts the closer on the pull side of the door with the arm reaching to the frame face, and it gives the most efficient control but leaves the arm projecting into the opening. A parallel arm mounts push side with the arm running back along the door, which keeps it tighter to the door and is what most commercial jobs specify for corridors and where the arm would otherwise be exposed. The 4050A-3077/PA is the regular arm version with the PA shoe. If you need a stop or hold-open built into the arm, that is a different arm assembly.
9) Does the LCN 4050A regular arm allow the door to open a full 180 degrees?
180 degrees is the swing range of the 3077/PA arm assembly. Whether you actually get it depends on the opening: wall returns, adjacent doors, and stops on the frame all limit swing before the arm does. Check clearance behind the door leaf first.
10) Does the LCN 4050A-3077/PA arm keep my door ADA compliant?
The arm assembly is ADA compliant, so replacing a damaged arm on a 4050A closer does not take an accessible opening out of compliance. Opening force is set at the closer body, not the arm, so after you swap the arm re-check spring power and adjust the closer to the force your facility requires.
11) What finishes does the LCN 4050A regular arm come in to match my existing closers?
Six finishes: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 696 brass. If you are patching one opening in a run of doors, match the finish code stamped on the closer cover rather than eyeballing it, since 690, 691 and 695 all read as bronze from across a lobby.
12) Is this LCN arm rated for a high traffic commercial door or is it light duty?
Grade 1, commercial rated. That is the heavy duty tier, which is what you want on school corridors, healthcare, and main entries where the door cycles all day. It is not a residential part.
13) Do I need a whole new closer or just an arm if my Sargent or Falcon unit is leaking?
A leaking body is not an arm problem. Once a closer weeps oil the hydraulics are done and the arm will not fix it, so plan on a complete closer such as the Sargent 1431-CPS TB EN heavy duty surface closer with parallel arm and compression stop, or the Sargent 25-CPS heavy duty parallel arm closer, both Grade 1. Buy an arm assembly like the LCN 4050A-3077/PA only when the body is sound and the arm or shoe is the damaged piece.
14) Is the Falcon 8230-3077PLCM the same part as an LCN 3077 arm since both use the 3077 number?
They are not interchangeable. The Falcon 8230-3077PLCM is a standard arm with track for Falcon 8230 Series automatic door operators, while the LCN 4050A-3077/PA is a regular arm with PA shoe for LCN 4050A Series manual surface closers. One drives a track on a powered operator, the other is a shoe-mounted arm on a manual closer - the shared 3077 digits do not make them a swap.
15) For a Grade 1 commercial opening, does an LCN 4050A arm hold the same rating as the Sargent alternatives?
The LCN 4050A-3077/PA regular arm with PA shoe is Grade 1 rated and ADA compliant for commercial use. On the Sargent side, the 25-CPS, 25-CPSH, 25-H and the 1431-CPS TB EN closer are all Grade 1 and heavy duty. A specifier standardizing a facility on Grade 1 door control can hold that grade with either line; the deciding factor is which closer body is on the door and whether the opening needs plain control, hold-open, or a stop.
16) What arm do I use on a center hung door with a floor pivot instead of a surface closer?
The LCN 4050A-3077/PA is a surface closer arm with a PA shoe and suits doors running an LCN 4050A Series surface closer. A center hung door on a floor pivot takes a different assembly - the Falcon OHC100A-DP is a center hung floor pivot with end load arm for OHC100 Series door closers. The two address different door hanging methods, so the pivot configuration decides which one you order.
