LCN 4050A-3077CNS 689 – Frequently Asked Questions

1) Will the LCN 4050A Cush-N-Stop arm work on a left-hand door and a right-hand door?
The 4050A-3077CNS Cush-N-Stop arm is non-handed, so the same part goes on left-hand and right-hand openings. For a property manager stocking spares across a building, that means one arm number covers every door running a 4050A closer instead of keeping two handed versions on the shelf.
2) Which door closers does the LCN 3077CNS arm fit?
This Cush-N-Stop arm is built for LCN 4050A Series closers. It is a replacement arm assembly, not a complete closer, so the closer body has to already be a 4050A. If the body on your door is a different LCN series or another brand, the arm will not mount.
3) Do I still need a separate door stop if I use a Cush-N-Stop arm?
No. The Cush-N-Stop arm carries the stop in the soffit shoe, so the arm itself limits how far the door swings and takes the abuse instead of a wall or floor stop. That is the reason to pick this arm over a plain regular arm: it protects the closer and the door from over-travel where there is nothing on the wall to catch it.
4) I need a door closer arm with a built-in stop that also holds the door open. What are my options?
The LCN 4050A-3077CNS Cush-N-Stop arm gives you the integrated stop but not a hold-open. For an arm that does both, the Sargent 25-CPSH is a heavy-duty hold-open parallel arm with a compression stop for Sargent 351 and 281 closers, and the Falcon SC60A-3049DS is a hold-open dead stop parallel arm assembly for the SC60A Series. Both are tied to their own closer bodies, so choose by the closer that is already mounted.
5) What is the closest Sargent equivalent to an LCN 4050A-3077CNS Cush-N-Stop arm?
The Sargent 25-CPS is the nearest counterpart. It is a heavy duty parallel arm with a compression stop for Sargent 351 and 281 door closers, so it builds the stop into the arm the same way the LCN 4050A-3077CNS builds a stop into the soffit shoe. The difference that decides the order is the closer body: the 4050A-3077CNS is made for LCN 4050A Series closers, while the 25-CPS mounts to Sargent 351 and 281 closers. Match the arm to the closer already on the door.
6) Can I order a Sargent 25-CPS or a 1431-CPS instead of an LCN Cush-N-Stop arm if I only need the arm?
The Sargent 25-CPS is an arm, so it is comparable in kind to the LCN 4050A-3077CNS even though it fits Sargent 351 and 281 closers rather than LCN 4050A Series closers. The Sargent 1431-CPS TB EN is a different purchase: it is a complete Grade 1 heavy duty surface door closer supplied with a parallel arm and compression stop, so ordering it replaces the whole closer, not just the arm.
7) Will a Falcon 8230-3077PLCM arm work on a manual surface closer like the LCN 4050A?
No. The Falcon 8230-3077PLCM is a standard arm with track for 8230 Series automatic door operators, so it belongs on a powered operator rather than a manual surface closer. The similar 3077 in the part number does not make it interchangeable. The LCN 4050A-3077CNS is a manual surface closer arm for LCN 4050A Series closers, non-handed, with the stop built into the soffit shoe.
8) Is a Cush-N-Stop arm the same thing as a hold-open arm?
They are different. The Cush-N-Stop arm stops the door at a set point and cushions it there, but does not hold the door open. If you want the door to stay open on its own, you need a hold-open arm instead. In the same class of parts, Sargent's 25-CPSH is a hold-open parallel arm with a compression stop, and the 25-H is a hold-open arm for standard and top jamb mounting on Sargent 351 and 281 closers.
9) What is the LCN Cush-N-Stop arm made of, and will it hold up on a high-traffic entrance?
Both the main arm and the forearm are solid forged steel. That is the heavy end of arm construction, which is what you want on a school corridor, hospital wing, or retail entry where the arm is taking the stop load every cycle. It is a commercial-duty part, not a residential one.
10) My whole closer is worn out, not just the arm. Should I buy an arm or a complete closer?
If the body is leaking oil or will not hold an adjustment, the arm will not fix it. The 3077CNS is a replacement arm only. In that case a complete unit is the buy, for example the Sargent 1431-CPS TB EN, a Grade 1 heavy duty surface closer that ships with a parallel arm and compression stop. Buy the arm when the body is sound and the arm is bent, seized, or the stop is beaten out.
11) The opening has a wall or column too close for a stop arm. What should I use instead of the Cush-N-Stop?
When the swing has to be caught somewhere other than the arm, look at a hold-open arm without a compression stop. The Sargent 25-H is a hold-open arm for 351 and 281 closers in standard and top jamb mount, and the Falcon SC70A-3049/PA is a hold-open arm supplied with a PA bracket for SC70A Series closers. The LCN 4050A-3077CNS carries its stop in the soffit shoe, which is what puts the arrest at the door itself.
12) My door is center hung on a floor pivot. Is the Cush-N-Stop arm the right part?
Not for that condition. The LCN 4050A-3077CNS is a surface closer arm for LCN 4050A Series closers with the stop in the soffit shoe. For a center hung floor pivot opening, the Falcon OHC100A-DP is a center hung floor pivot with an end load arm for OHC100 Series door closers, which is the overhead concealed arrangement that a center hung door needs.
13) I am standardizing stop arms across a facility on ADA openings. How do the Cush-N-Stop and the Sargent compression stop arms line up?
The LCN 4050A-3077CNS is an ADA compliant commercial arm with solid forged steel main arm and forearm and a non-handed design, so one part number covers both hands of door across a building running LCN 4050A Series closers. On the Sargent side, the 25-CPS and 25-CPSH are Grade 1 heavy duty parallel arms with a compression stop for 351 and 281 closers, the CPSH adding hold-open. Standardization follows the closer line already installed, so survey which closer bodies your doors carry before you settle on one arm.
14) What finishes does the LCN 4050A Cush-N-Stop arm come in?
Six finishes: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 696 brass. Match the finish to the closer body already on the door, since a replacement arm in the wrong number will read as a mismatch from across the lobby even when the fit is right.
