LCN 4020-3077 695 – Frequently Asked Questions

1) Will the LCN 4020-3077 regular arm fit any LCN door closer, or only the 4020 Series?
It's built for LCN 4020 Series closers only. The 4020-3077 is a series-specific replacement arm, so pull the model number off the closer body before ordering. If the body is a different LCN series, this arm is the wrong part.
2) Do I need to specify left hand or right hand for the LCN 4020 regular arm?
No handing to specify. The 4020-3077 regular arm is non-handed, so one part covers both left and right hand openings. That makes it easy to stock a couple on the shelf for a building with mixed swings.
3) Can I just replace the arm instead of the whole door closer if the arm is bent or broken?
That's exactly what the 4020-3077 is for. It's a replacement arm assembly, so if the closer body still holds oil and controls the door but the arm has been sprung, forced, or lost, you swap the arm and keep the existing body and mounting holes. For a property manager with a run of 4020s, that's a far smaller job than re-drilling for a new closer.
4) I need the door to stop before it hits an adjacent wall - what arm should I use instead of a regular arm?
A regular arm like the LCN 4020-3077 provides standard door control with no built-in stop, so the opening needs a separate overhead or floor stop. If you want the stop built into the arm, Sargent offers the 25-CPS heavy duty parallel arm with compression stop for 351 and 281 closers, and the 25-CPSH, which adds hold-open to the same compression stop parallel arm. Falcon's SC60A-3049DS is a hold-open dead stop parallel arm assembly for SC60A closers. All three are parallel arm assemblies, so they mount on the pull side with a shoe on the door face rather than in the regular arm configuration.
5) Is the LCN 4020-3077 regular arm interchangeable with a Sargent 25-H arm?
No. The LCN 4020-3077 is a regular arm built specifically for LCN 4020 Series closers, and the Sargent 25-H is a hold-open arm for Sargent 351 and 281 closers in standard and top jamb mount. Each arm is matched to its own closer body and spindle, so an LCN 4020 body needs the 4020-3077 arm and a Sargent 351 or 281 body needs the Sargent part. The other difference is function: the 4020-3077 is a plain regular arm with no hold-open feature, while the 25-H holds the door open.
6) The Falcon 8230-3077PLCM has the same 3077 number - will it work on an LCN 4020 closer?
No. The Falcon 8230-3077PLCM is a standard arm with track for Falcon 8230 Series automatic door operators, while the LCN 4020-3077 is a regular arm for LCN 4020 Series manual surface closers. Beyond the different host units, the Falcon part is a track arm assembly and the LCN part is a regular arm, so the geometry and the mounting on the door are not the same. Match the arm to the closer or operator body already on the door.
7) What finishes does the LCN 4020 regular arm come in?
Thirteen finishes, so you can match the arm to the closer body and the rest of the opening: 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 will see most often on existing commercial installs.
8) Is the LCN 4020 regular arm ADA compliant for an accessible opening?
Yes, the 4020-3077 arm carries an ADA compliant designation. Compliance on the opening still depends on the closer being adjusted to the correct opening force and closing speed once the arm is back on.
9) What is the closest hold-open option if the tenant wants the door to stay open on a 4020?
The LCN 4020-3077 is a plain regular arm and does not hold the door open. For a hold-open arm on other closer families, Falcon lists the SC70A-3049/PA, a hold open arm with PA bracket for SC70A Series closers, and Sargent lists the 25-H hold-open arm for 351 and 281 closers in standard and top jamb mount. Both are tied to their own closer bodies, so the choice follows whichever closer is already hung on the frame.
10) For a center hung door, can I use the LCN 4020-3077 regular arm?
A regular arm such as the LCN 4020-3077 is intended for standard surface closer mounting on a butt hung commercial door. A center hung leaf is a different arrangement, and the part that suits it is something like the Falcon OHC100A-DP, a center hung floor pivot with end load arm for OHC100 Series door closers. Confirm the pivot and closer family on the opening before ordering either one.
11) I am replacing the arm only versus the whole closer - what is the difference in what I order?
The LCN 4020-3077 is a replacement arm component for LCN 4020 Series closers, so the existing closer body stays on the door and only the arm assembly changes. If the body itself is failing, a complete unit is the order instead, such as the Sargent 1431-CPS TB EN, a Grade 1 heavy duty surface door closer supplied with a parallel arm and compression stop. That route replaces body, arm and mounting together and changes the mounting configuration to parallel arm.
12) Is the LCN 4020 arm suitable for a residential door?
It's catalogued for commercial use, and the 4020 Series is a commercial closer line used in offices, schools, healthcare, retail, warehouses, multi-tenant residential, and government buildings. Nothing stops it working on an apartment or common-area door, but it is only the right part if there is already a 4020 Series closer on that door.
