LCN 4110-3077CNS 652 – Frequently Asked Questions

1) Will the LCN 4110-3077CNS Cush-N-Stop arm work on my LCN 4110 closer?
That's exactly what it's built for. The 3077CNS Cush-N-Stop arm is an LCN 4110 Series part, so it fits 4110 closer bodies. It is not a universal arm, so if the closer body on the door is a 1460, 4040XP or any other LCN series, this is the wrong arm for it.
2) Do I need to order a left hand or right hand version of the LCN 3077CNS arm?
No handing to specify. The Cush-N-Stop arm is non-handed, so the same part goes on a left hand or right hand opening. Pick the finish and order it.
3) Does the LCN Cush-N-Stop arm act as a door stop, or do I still need a floor or wall stop?
The stop is built into the arm. The Cush-N-Stop soffit shoe carries an integral cushioned stop that catches the door at the open position and absorbs the shock, which is what keeps a door from slamming into a wall and chewing up the closer and hinges. On a wall the door would otherwise hit, that's the point of the CNS arm over a plain parallel arm. It is a stop, not a hold-open: it will not keep the door standing open.
4) Is this a complete door closer or just the arm?
Arm only. The 4110-3077CNS is a replacement arm assembly, main arm plus forearm and the soffit shoe with the cushioned stop in it. There's no closer body, no cover and no mounting plate in it. If the closer body itself is leaking oil or has lost its adjustment, an arm won't fix that and a complete closer is the part needed.
5) My closer is a Sargent, not an LCN. Is there an equivalent cushioned stop parallel arm?
Don't cross brands on closer arms, the pinion splines and shoe geometry differ. For a Sargent 351 or 281 closer, the Sargent 25-CPS is the parallel arm with compression stop, and the 25-CPSH is the same thing with hold-open added. On a Falcon SC60A the counterpart is the SC60A-3049DS dead stop parallel arm. The LCN 3077CNS only goes on an LCN 4110.
6) What is the Sargent equivalent of an LCN 4110-3077CNS Cush-N-Stop parallel arm?
The closest Sargent counterpart is the 25-CPS, a heavy duty parallel arm with compression stop for Sargent 351 and 281 closers. Both put the stop in the arm assembly itself rather than relying on a separate wall or floor stop, and both mount parallel arm. The difference that matters when ordering is the closer body: the 4110-3077CNS is built for LCN 4110 Series closers, while the 25-CPS is a Sargent 351/281 part, so the arm follows whichever closer is already on the door. Sargent rates the 25-CPS Grade 1 heavy duty.
7) I need a stop arm that also holds the door open - what should I use instead of the 4110-3077CNS?
The 4110-3077CNS Cush-N-Stop is a stop arm only; it cushions and stops the swing but does not latch the door open. For hold-open plus stop in one assembly, Sargent's 25-CPSH is a heavy-duty hold-open parallel arm with compression stop for 351 and 281 closers, and Falcon's SC60A-3049DS is a hold-open dead stop parallel arm assembly for SC60A closers. All three are parallel arm assemblies, so the mounting side of the door does not change - only the closer family and whether hold-open is included.
8) What do I use on an opening that will not take a parallel arm mount?
The 4110-3077CNS is a parallel arm assembly and needs the soffit of the frame to land its shoe. Where that face is not available, the Sargent 25-H is a hold-open arm for standard and top jamb mount on 351 and 281 closers, which puts the arm on the pull side or the frame face instead. For a center hung opening, Falcon's OHC100A-DP is a center hung floor pivot with end load arm for OHC100 Series closers. Neither carries the 4110-3077CNS built-in cushioned stop, so a separate stop has to be planned for on those openings.
9) What is the difference between a parallel arm and a regular arm on a door closer?
Mounting side and projection. The 3077CNS is a parallel arm: the closer goes on the pull side of the door with the arm running flat along the face and the shoe on the frame soffit, so nothing sticks out into the opening. A regular (standard) arm mounts on the push side and projects out from the frame. Parallel arm is the usual choice in corridors, on out-swinging exterior doors, and anywhere the arm would be vulnerable or in the way. Switching an existing closer from one to the other is not just an arm swap, the closer body location changes too.
10) Will replacing my closer arm with the LCN Cush-N-Stop keep the door ADA compliant?
The 4110-3077CNS is listed ADA compliant, so the arm itself is not what takes an opening out of compliance. Opening force and closing speed are set at the closer body and its valves, not at the arm, so those still need to be adjusted on the closer after the arm goes on.
11) What finishes does the LCN 3077CNS Cush-N-Stop arm come in?
Thirteen, so matching the rest of the door hardware in a building is usually possible: 616 satin bronze blackened, 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, 651 bright chrome, 652 satin chrome, 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze and 696 brass. 689 aluminum and 695 dark bronze are the two you see most often on commercial openings, and 652 satin chrome is the common match to satin stainless lever trim.
12) I need the door to stay open as well as have a stop. Does the Cush-N-Stop do that?
No. The CNS arm cushions and stops the swing, but it will not hold the door open. If a hold-open is required, that's a different arm: the Sargent 25-CPSH combines hold-open with a compression stop on 351 and 281 closers, and the Falcon SC70A-3049/PA is a hold-open arm with a PA bracket for SC70A closers. On an LCN 4110, ask for the hold-open version of the arm rather than the CNS.
13) Can I standardize the same Cush-N-Stop arm across a whole building of doors?
Yes, as long as every opening runs an LCN 4110 closer mounted parallel arm. Because the arm is non-handed, one part number covers left and right hand doors, so a property manager stocking spares only needs the one arm in the chosen finish rather than a handed pair. Doors with a different closer series or a top jamb or regular arm mount need a different part.
14) Is the Falcon SC70A-3049/PA a substitute for the LCN 4110-3077CNS?
No. The SC70A-3049/PA is a hold-open arm supplied with a PA bracket for Falcon SC70A Series closers, so it serves a different closer family and it is a hold-open rather than a cushioned stop arm. The 4110-3077CNS is a non-handed Cush-N-Stop arm for LCN 4110 Series closers with the stop built into the soffit shoe. The two are not interchangeable on the same closer body.
15) My closer body is worn out too - do I replace just the arm or buy a complete closer with a stop arm?
If the 4110 Series closer body is still sound, the 4110-3077CNS replaces only the arm and keeps the existing closer and its mounting holes. If the body is failing, a complete unit makes more sense: the Sargent 1431-CPS TB EN is a heavy duty surface door closer that ships with a parallel arm and compression stop as one Grade 1 assembly, so it covers the closer and the cushioned stop function in a single part number. Both routes end up with a parallel arm stop on the door.
16) Will a Falcon 8230-3077PLCM arm work in place of the LCN 4110-3077CNS?
They share a 3077 number in the part string but they are different parts. The Falcon 8230-3077PLCM is a standard arm with track for Falcon 8230 Series automatic door operators - a track arm for a powered operator. The 4110-3077CNS is a manual-closer arm with a built-in cushioned stop for LCN 4110 Series closers, non-handed, in a parallel arm configuration. A track arm gives no stop function and will not mount to a 4110 closer.
17) I am standardizing stop arms across a facility that has both LCN and Sargent closers - what do I order?
The arm has to match the closer body, so one part number will not cover a mixed fleet. Doors with LCN 4110 Series closers take the 4110-3077CNS, which is non-handed and comes in thirteen finishes including 689 Aluminum, 652 Satin Chrome and 695 Dark Bronze. Doors with Sargent 351 or 281 closers take the 25-CPS for stop only or the 25-CPSH where hold-open is also wanted, both Grade 1 heavy duty. Specifying that pairing by closer family keeps the stop function and the parallel arm mounting consistent across the whole facility.
18) Is the LCN 3077CNS arm strong enough for a school or hospital corridor door?
Both the main arm and the forearm are solid forged steel, and it's a commercial-rated part. Forged is what you want on a stop arm in particular, because the arm takes the impact every time the door is thrown open. It's the usual spec for schools, healthcare, offices, retail and multi-family corridors where doors get abused.
