LCN 4000T-3077T 652 – Frequently Asked Questions

1) Will the LCN 4000T-3077T standard arm fit a left-hand or right-hand door?
Handing isn't a decision here. The 4000T-3077T standard arm is non-handed, so one part covers both left and right hand openings. That's useful if you stock spares across a building: one arm number serves every 4000T closer regardless of swing.
2) Does the LCN 4000T-3077T arm work on any LCN door closer, or only the 4000T Series?
Only 4000T Series closers. The 3077T standard arm is built specifically for the 4000T Series and is not a general LCN arm, so before you order, confirm the body on the door is a 4000T. If the closer is a different LCN series, this arm is the wrong part.
3) Do I need anything else to complete the LCN 4000T-3077T arm assembly?
Yes, a roller. The 3077T arm requires a separate roller component to make up the complete arm assembly, and that roller is sold on its own. Order both together or the arm goes on the wall incomplete.
4) Is the LCN 4000T-3077T a replacement part or a whole new door closer?
It's a replacement part only, the arm, not the closer body. If the hydraulic body on the door is failing (leaking oil, won't hold a speed adjustment), swapping the arm won't fix it and you need a complete closer instead. Use the 3077T when the arm itself is bent, seized, or missing and the 4000T body is still good.
5) Is a standard arm the right choice, or do I need a parallel arm or hold-open arm?
A standard arm mounts on the pull side of the door and is the plain closing arm, no stop, no hold-open. Pick it when you want the door to close every time and nothing catches it. If you need the door to stay open, look at a hold-open assembly like the Sargent 25-H, which is made for standard and top jamb mounting. If the door has to be stopped at a set opening angle so it can't hit a wall, a parallel arm with a stop is the type to use, such as the Sargent 25-CPS with compression stop or the Falcon SC60A-3049DS dead stop parallel arm. Those are different closer families though, so match the arm to the closer body you have.
6) What is the equivalent standard arm for a Falcon 8230 operator instead of the LCN 4000T arm?
They are not interchangeable. The 4000T-3077T standard arm is built for 4000T Series door closers, so it belongs on an LCN 4000T body. For a Falcon 8230 opening, the arm to use is the Falcon 8230-3077PLCM standard arm with track, which is made for the 8230 Series automatic door operators. Match the arm to the closer or operator series already on the door rather than to the arm shape.
7) I need a hold-open arm rather than a standard arm - what should I order?
The 4000T-3077T is a standard arm, so it does not hold the door open. For hold-open, the arm has to match the closer body: the Sargent 25-H is a hold-open door closer arm for 351 and 281 closers in regular and top jamb mount, the Sargent 25-CPSH is a heavy-duty hold-open parallel arm with compression stop for 351 and 281 closers, and the Falcon SC70A-3049/PA is a hold open arm with PA bracket for SC70A Series closers. Choose by the closer already installed.
8) Is the Falcon 8230-3077PLCM a drop-in substitute since the part number also reads 3077?
No. The shared 3077 digits are a coincidence of two manufacturers' numbering, not evidence of a common fit. The 4000T-3077T is an LCN component for 4000T Series closers, while the 8230-3077PLCM is a Falcon standard arm with track for the 8230 Series automatic door operators. Different series, different manufacturer, and the Falcon part is a track arm rather than a plain standard arm.
9) The door is center hung on a floor pivot - will the 4000T standard arm work?
The 4000T-3077T standard arm is a surface closer arm for 4000T Series closers and assumes a conventionally hung door. For a center hung door running on a floor pivot, the Falcon OHC100A-DP is a center hung floor pivot with end load arm for OHC100 Series door closers, which is the configuration that suits that opening.
10) What finish should I order to match the other door closers in my building?
Thirteen finishes cover the 3077T arm: 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. Read the BHMA number off the closer cover already on the door, 689 aluminum and 693 gloss black being the two most common on commercial openings, and order the arm to match rather than eyeballing the color.
11) Is there an equivalent standard arm from another brand if I can't get the LCN 4000T-3077T?
Closer arms are not cross-brand parts, so nothing substitutes directly on a 4000T body. The closest arm of the same kind is the Falcon 8230-3077PLCM standard arm with track, but that one is built for Falcon 8200 Series automatic operators and won't mount to an LCN closer. If the LCN body itself is being replaced, then a complete Grade 1 heavy duty unit like the Sargent 1431-CPS TB EN closer with parallel arm and compression stop becomes an option, since you'd be changing the closer and the arm together.
12) Will replacing the arm on my LCN 4000T closer keep the door ADA compliant?
The 4000T-3077T arm carries an ADA compliant design, but compliance depends on the install: the arm has to be fitted and the closer adjusted properly for opening force and closing speed on the finished opening. Fitting the arm alone doesn't settle it, the adjustment on the closer body does.
13) My closer arm is failing but the closer body is fine - can I just replace the arm, or do I need a whole closer?
On a 4000T Series opening the arm itself is a replacement part, so the 4000T-3077T standard arm swaps in without touching the closer body. Note it is supplied for use with a separate roller component to complete the assembly. Some comparable items are not arms at all: the Sargent 1431-CPS TB EN is a heavy duty Grade 1 surface door closer supplied with a parallel arm and compression stop, and the Sargent 25-CPS is a heavy duty Grade 1 parallel arm door closer with compression stop - those replace the closer, not just the arm.
14) We are standardizing arms across a facility - does one arm cover every closer we own?
No single arm covers a mixed fleet, because arms are tied to the closer series. The 4000T-3077T covers 4000T Series closers and is non-handed, so it does not need to be specified left or right. Sargent 25-CPS, 25-CPSH and 25-H arms are for 351 and 281 closers, the Falcon SC60A-3049DS is for SC60A Series, the SC70A-3049/PA is for SC70A Series, and the 8230-3077PLCM is for 8230 Series operators. Standardize on closer families first, then the arm follows.
15) What is the difference between the 4000T standard arm and a parallel arm assembly?
The 4000T-3077T is a non-handed standard arm for 4000T Series closers, used with a separate roller to complete the assembly. A parallel arm assembly mounts the closer on the pull side with the arm running parallel to the door face: the Sargent 25-CPS is a heavy duty parallel arm with compression stop for 351 and 281 closers, and the Falcon SC60A-3049DS is a hold-open dead stop parallel arm assembly. The mounting position and what the arm does at the end of swing are what separate them.
16) Does swapping to a different manufacturer's arm affect ADA compliance on the opening?
The 4000T-3077T is ADA compliant when properly installed and adjusted on a 4000T Series closer, and it is a commercial-grade component. Compliance depends on the closer and arm working as a matched set on the door, so a cross-brand arm on an LCN body is not a compliant assembly. If the closer body is being changed instead, the Sargent 1431-CPS TB EN is a heavy duty Grade 1 surface closer supplied with its own parallel arm and compression stop.
17) Is the LCN 4000T standard arm heavy enough for a high traffic entrance, or is it a light duty part?
Commercial rated, not residential. The 3077T is built to LCN commercial standards for high traffic openings, which is why it turns up in offices, schools, hospitals, retail, warehouses, apartment buildings, and municipal facilities. For a low use interior door in a house it's more part than the opening needs.
18) I need to match the finish on the other doors - how many finishes does the 4000T standard arm come in?
The 4000T-3077T standard arm is offered in thirteen finishes, including 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. Cross-brand arms such as the Sargent 25-H or the Falcon SC70A-3049/PA are selected by closer series rather than by matching an LCN finish code, so a finish match across brands should be confirmed against the actual door hardware on site.
