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

1) Do I have to specify handing when ordering the LCN 4050A-3049EDA/G arm?
Yes. The 4050A extra duty hold open arm is a handed assembly, ordered left hand or right hand, so you need to know which way the door swings before you order. Both handings come in all six finishes: 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze and 696 brass.
2) What does the /G in 4050A-3049EDA/G mean?
The /G designates the 62G shoe, which gives additional blade stop clearance. That is what lets the arm coexist with an overhead holder or stop and other hardware mounted on the same frame face. If nothing else is competing for that space, the standard shoe version is enough.
3) Will this arm fit any LCN closer or only the 4050A?
It is built for LCN 4050A Series closer bodies. It is a replacement part for that series, not a universal arm, so match the closer body stamping before ordering.
4) Is this a complete door closer or just the arm?
Arm only. The 4050A-3049EDA/G is the parallel arm and shoe assembly, a replacement part for an existing 4050A closer. If you need a full closer with a parallel arm, look at a complete unit such as the Sargent 1431-CPS TB EN heavy duty surface closer with parallel arm and compression stop.
5) My door needs a stop built into the arm, not just hold open. Is this the right part?
No. This LCN arm is hold open without an integral dead stop. For a parallel arm that stops the door, the Falcon SC60A-3049DS is a hold-open dead stop parallel arm assembly, and the Sargent 25-CPSH is a heavy duty hold-open parallel arm with compression stop.
6) What is the closest hold open parallel arm to the LCN 4050A-3049EDA/G if the closer body is not an LCN?
The 4050A-3049EDA/G is a hold open parallel arm built for LCN 4050A Series closers, so it is tied to that closer body. On a Sargent 351 or 281 closer, the equivalent function is the Sargent 25-CPSH heavy-duty hold-open parallel arm with compression stop. On a Falcon SC70A closer, the matching part is the SC70A-3049/PA hold open arm with PA bracket. Match the arm to the closer series you already have on the door rather than to the arm number.
7) I need a hold open arm that also stops the door at a set point instead of just holding it open. What should I look at?
The LCN 4050A-3049EDA/G uses a 62G shoe that adds blade stop clearance so it can work alongside an overhead holder, but the stop function comes from that separate hardware. If you want the stop built into the arm, the Falcon SC60A-3049DS is a hold-open dead stop parallel arm assembly, and the Sargent 25-CPSH combines hold-open with a compression stop. Both are tied to their own closer series, so confirm the closer body first.
8) Do I need a parallel arm, or is there a hold open arm that works for regular and top jamb mount?
The LCN 4050A-3049EDA/G is a parallel arm configuration, mounted on the pull-side face of the door with the shoe on the frame soffit. If your opening calls for regular (pull side) or top jamb mounting instead, the Sargent 25-H is a hold-open arm for standard and top jamb mount on Sargent 351 and 281 closers. Choose by which face of the door the closer body sits on.
9) Will the LCN 4050A-3049EDA/G work on an automatic door operator or a center hung pivot door?
No. The 4050A-3049EDA/G is a replacement arm for LCN 4050A Series surface closers on swing doors. An automatic operator needs the operator maker's own linkage, such as the Falcon 8230-3077PLCM standard arm with track for 8230 Series automatic door operators. A center hung pivot opening uses a different assembly again, such as the Falcon OHC100A-DP center hung floor pivot with end load arm for OHC100 Series closers.
10) When should I use an extra duty arm instead of a standard parallel arm?
Pick the extra duty version where the door gets abused: school corridors, warehouse and dock doors, high traffic retail entries. The main arm and forearm are forged solid steel for those conditions. On a low abuse interior office door a standard arm does the same job at less bulk.
11) Does a parallel arm hold open setup meet ADA requirements?
The 4050A hold open extra duty arm is ADA compliant for accessible door operation in commercial openings. Actual opening force still depends on how the closer body is sized and adjusted, since the arm alone does not set spring power.
12) What hold open arm do I use if my closer is top jamb or regular arm mounted instead of parallel?
This LCN assembly is parallel arm only. For a hold open arm on standard or top jamb mount, the Sargent 25-H covers 351 and 281 closers in those mounts. Falcon's SC70A-3049/PA is a hold open arm with PA bracket for SC70A Series closers.
13) Can I match this arm to the other closers already in my building?
Finish matching is straightforward: six finishes are offered, 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze and 696 brass, which covers the usual LCN finish range on existing openings. Mechanically it only goes on 4050A Series closer bodies, so a mixed fleet of LCN closers may need different arms per series.
14) Is there a simpler parallel arm option if I do not need the hold open feature?
The LCN 4050A-3049EDA/G includes the hold open function, which lets the door be parked open. If the opening is a fire-rated or egress door where hold open is not wanted, a non-hold-open parallel arm such as the Sargent 25-CPS heavy-duty parallel arm with compression stop covers the same mounting style without the hold open. The 25-CPS fits Sargent 351 and 281 closers, so it is not a drop-in for an LCN 4050A body.
15) My closer body is worn out too. Should I buy the arm or replace the whole closer?
The LCN 4050A-3049EDA/G is a replacement arm only, so it makes sense when the 4050A body is sound and the arm is bent or the hold open has failed. If the body itself is leaking or the sweep no longer controls, a complete unit is the better call: the Sargent 1431-CPS TB EN is a Grade 1 heavy duty surface door closer supplied with a parallel arm and compression stop, which replaces body and arm together on a new mounting pattern.
16) For an abuse-prone door in a school corridor, how does the LCN 4050A-3049EDA/G compare to a heavy duty Sargent arm?
The 4050A-3049EDA/G is an extra duty arm with forged solid steel main arm and forearm, specified for potentially abusive commercial installations, and it is handed left or right. The Sargent 25-CPSH and 25-H are rated heavy duty and Grade 1 for the same class of traffic but are built for Sargent 351 and 281 closers. Both routes address high-abuse openings; the deciding factor is which closer body is already hung on the door.
