LCN 4050A-3077EDA/G 689 – Frequently Asked Questions

1) Will the LCN 3077EDA arm work on any LCN closer, or only the 4050A?
The 3077EDA/G extra duty arm is built for LCN 4050A Series door closers. It is sold as a replacement part for that series, so if the closer body on the door is something other than a 4050A, this is not the arm for it.
2) Do I need to order a left hand or right hand version of the LCN 4050A extra duty arm?
No handing to specify. The 4050A extra duty arm is non-handed, so one part covers both left and right hand doors. That is useful if you are stocking spares for a building with openings swinging both ways.
3) What does the 62G shoe on the LCN 4050A arm actually do for me?
The G shoe gives extra blade stop clearance. On an opening that already has an overhead holder or stop, or other hardware crowding the soffit, the standard shoe can interfere. The 62G shoe moves the arm clear of it. If your door has nothing at the head, you do not need the G version.
4) The closer body is shot, not just the arm. What do I order instead of the 4050A-3077EDA/G arm?
The LCN 4050A-3077EDA/G is a replacement arm only, so it does nothing for a failed closer body. If you are replacing the whole unit, the Sargent 1431-CPS TB EN is a Grade 1 heavy duty surface door closer supplied with a parallel arm and compression stop, and the Sargent 25-CPS is a Grade 1 heavy duty parallel arm closer with compression stop. Both give you a complete parallel arm assembly rather than a component swap.
5) What is the closest parallel arm replacement to the LCN 4050A-3077EDA/G if the closer on the door is a Sargent 351 or 281?
The LCN 4050A-3077EDA/G is built for LCN 4050A Series closers and will not mount to a Sargent body. For a Sargent 351 or 281 closer, the Sargent 25-CPS heavy duty parallel arm with compression stop is the matching parallel arm assembly, and the Sargent 25-CPSH is the same compression stop parallel arm in a hold-open version. Match the arm to the closer brand and series first; the LCN arm's forged solid steel main and forearm only helps you if the body is a 4050A.
6) I need the door to hold open. Is there an arm like the LCN 4050A-3077EDA/G that does that?
The LCN 4050A-3077EDA/G is an extra duty parallel arm with a 62G shoe for added blade stop clearance; the hold-open function is not part of it. Arms that do include hold-open in this class are the Sargent 25-H hold-open arm for 351 and 281 closers in standard and top jamb mount, the Sargent 25-CPSH hold-open parallel arm with compression stop, and on the Falcon side the SC70A-3049/PA hold open arm with PA bracket for SC70A Series closers and the SC60A-3049DS hold-open dead stop parallel arm assembly. Each is tied to its own closer series, so pick by the closer already on the door.
7) Does the LCN 4050A-3077EDA/G work on an automatic operator or a center hung pivot door?
No. The LCN 4050A-3077EDA/G is a non-handed parallel arm for LCN 4050A Series manual surface closers. For an automatic operator, the Falcon 8230-3077PLCM is a standard arm with track for 8230 Series automatic door operators. For a center hung door, the Falcon OHC100A-DP is a center hung floor pivot with end load arm for OHC100 Series closers. Those are different mounting systems, not finish or duty variations of the LCN arm.
8) Is this parallel arm strong enough for a school or hospital door that gets abused?
That is what it is for. The main arm and forearm are forged solid steel, built for potentially abusive installations, and the part is rated commercial rather than residential. Typical uses include schools, healthcare, retail, industrial buildings and multi-tenant residential.
9) Does replacing the arm affect ADA compliance on the opening?
The 4050A extra duty arm is an ADA compliant component, so swapping it in keeps the door control assembly on the accessibility side of the line. Opening force still depends on how the closer itself is adjusted after the arm goes on.
10) Can I use a Sargent or Falcon arm on my LCN 4050A closer?
No. Closer arms are matched to their own manufacturer's closer body. The Sargent 25-H and 25-CPS arms are for Sargent 351 and 281 closers, and the Falcon SC70A-3049/PA is for Falcon SC70A closers. For an LCN 4050A, use the LCN 4050A arm.
11) For a top jamb mount instead of parallel arm, what should I use rather than the 4050A-3077EDA/G?
The LCN 4050A-3077EDA/G is configured as a parallel arm with the 62G shoe. For a top jamb application, the Sargent 25-H is a hold-open arm listed for standard and top jamb mount on 351 and 281 closers, and the Sargent 1431-CPS TB EN is a Grade 1 heavy duty closer supplied with top jamb bracket. Confirm which closer body is on the door before ordering either.
12) For a high abuse opening in a school, is the LCN 4050A-3077EDA/G arm or a Sargent parallel arm closer the better standardization choice?
They cover different scopes. The LCN 4050A-3077EDA/G is a non-handed extra duty arm with forged solid steel main and forearm intended for potentially abusive installations, ADA compliant and commercial rated, and it standardizes the arm across doors already running LCN 4050A closers. The Sargent 1431-CPS TB EN and 25-CPS are Grade 1 heavy duty units, so standardizing on those means replacing the closer as well as the arm. If your existing fleet is LCN 4050A, the arm keeps the bodies in service.
13) What finishes does the LCN 4050A extra duty arm come in?
Six: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze and 696 brass. Match the number to the closer body already on the door so the arm does not read as a mismatched repair.
