LCN 4050A-3049EDA RH 689 – Frequently Asked Questions

1) Do I have to specify handing when ordering the LCN 4050A-3049EDA hold open arm?
Yes, handing is required. The 3049EDA extra duty arm is a handed part and is ordered as either LH (left hand) or RH (right hand). Determine the hand of the door the closer is mounted on before ordering, because the two are not interchangeable.
2) Which LCN closers does the 3049EDA arm fit?
It is a replacement arm for LCN 4050A Series door closers, sold as a service part rather than a complete closer. If the body on your door is a different LCN series, this arm is not the right part for it.
3) Is a forged steel closer arm worth it on a door that keeps getting abused?
That is exactly what the 3049EDA is for. Both the main arm and forearm are forged solid steel, built for potentially abusive installations where a standard arm bends or breaks. On entries in schools, warehouses, and high traffic multi-tenant buildings, this is the arm you put on after a standard one has already failed.
4) I need a hold open arm but my closer is a Sargent or Falcon, not an LCN. What do I order?
Closer arms are not cross-brand parts, so the LCN 3049EDA will not go on another maker's body. For Sargent 351 or 281 closers, the 25-H hold open arm covers regular and top jamb mount, and the 25-CPSH is the hold open parallel arm with compression stop. On Falcon, the SC70A-3049/PA is the hold open arm with PA bracket for SC70A closers and the SC60A-3049DS is the hold open dead stop parallel arm for SC60A.
5) I need a hold open arm that also stops the door at a set point. What are my options besides the LCN 4050A-3049EDA?
The LCN 4050A-3049EDA provides hold open with the hold open adjusted at the shoe, but it is not described as a stop arm. If the opening needs the arm itself to limit swing, the Falcon SC60A-3049DS is a hold-open dead stop parallel arm assembly for SC60A Series closers, and the Sargent 25-CPSH is a heavy-duty hold-open parallel arm with compression stop for 351/281 closers. Both are tied to their own closer families, so confirm which closer body is on the door before ordering.
6) If the closer body itself is worn out, what do I buy instead of just the LCN 4050A-3049EDA arm?
The LCN 4050A-3049EDA is a replacement part, an arm only, for an existing 4050A Series closer. When the closer body is the problem, a complete unit is the right call: the Sargent 1431-CPS TB EN is a Grade 1 heavy duty surface door closer with parallel arm and compression stop, and the Sargent 25-CPS is a Grade 1 heavy duty parallel arm door closer with compression stop compatible with 351/281 applications.
7) What is the closest hold open closer arm to the LCN 4050A-3049EDA if the closer on the door is a Sargent 351 or 281?
The LCN 4050A-3049EDA is a hold open extra duty arm built for LCN 4050A Series closers, so it will not serve a Sargent body. For Sargent 351 or 281 closers, the Sargent 25-H is a hold-open door closer arm for standard and top jamb mount, and the Sargent 25-CPSH is a heavy-duty hold-open parallel arm with compression stop for those same closers. Match the arm to the closer brand and series first, then to the mounting you have on the door.
8) Where do you adjust the hold open point on this LCN extra duty arm?
Adjustment is made at the shoe. The hold open position on the 3049EDA is set there, so once the arm is installed you set the hold open angle at the shoe rather than inside the closer body.
9) What finishes does the LCN 4050A hold open extra duty arm come in?
Six finishes: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 696 brass. Each is available in both left hand and right hand, so you can match the arm to closer bodies already on the other openings in the building.
10) Does this arm keep the opening ADA compliant?
The 4050A-3049EDA is an ADA compliant component for accessible door hardware applications. Opening force still depends on how the closer itself is adjusted after the arm is installed.
11) Is there a hold open arm for a Falcon SC70A closer like the LCN extra duty arm?
Yes. The Falcon SC70A-3049/PA is a hold open arm supplied with a PA bracket for SC70A Series door closers. The LCN 4050A-3049EDA is the hold open extra duty arm for the LCN 4050A Series with forged solid steel main arm and forearm for potentially abusive installations. The two are not interchangeable; each mounts to its own closer body.
12) Will a Falcon 8230-3077PLCM arm work in place of the LCN 4050A-3049EDA?
No. The Falcon 8230-3077PLCM is a standard arm with track for 8230 Series automatic door operators, so it belongs to a powered operator rather than a manual surface closer. The LCN 4050A-3049EDA is a handed hold open extra duty arm for LCN 4050A Series closers, adjusted at the shoe. They serve different door control systems.
13) My door is center hung on a floor pivot. Is the LCN 4050A-3049EDA the right arm?
No. The LCN 4050A-3049EDA is a surface closer arm for the LCN 4050A Series. 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 arrangement that application calls for.
14) For a high abuse opening, how does the LCN 4050A-3049EDA compare with the Sargent hold open arms?
The LCN 4050A-3049EDA uses forged, solid steel main arm and forearm specifically for potentially abusive installations, and it is a handed part ordered left hand or right hand. The Sargent 25-H and 25-CPSH are heavy duty hold-open arms carrying a Grade 1 rating, with the 25-CPSH adding a compression stop. The deciding factor is the closer already on the door, since each arm fits only its own closer family.
15) Is this arm suitable for a residential door?
It is a commercial part. The 4050A extra duty arm is built for commercial door controls in offices, schools, healthcare, retail, warehouses, and government buildings. On a light residential door it is more arm than the opening needs.
