Falcon SC70A-3049DS AL – Frequently Asked Questions

1) Will the Falcon SC70A-3049DS arm work on my LCN or Sargent door closer?
No. The SC70A-3049DS arm is built for Falcon SC70A Series closers only, so it won't mount to an LCN or Sargent body. If you're replacing a hold-open arm on a Sargent 351 or 281 closer, the Sargent 25-CPSH heavy duty hold-open parallel arm with compression stop is the part built for those bodies, and the Sargent 25-H hold-open arm covers regular and top jamb mount. For LCN, the 1250-3049/PA hold open arm assembly with parallel arm shoe fits the 1250 Series and the 4010-3049 hold open arm fits the 4020 Series.
2) What does the dead stop on this Falcon parallel arm actually do, and do I still need a floor or wall stop?
The dead stop is a positive mechanical stop built into the arm, so the arm itself limits how far the door swings and prevents over-travel. That's the point of a DS arm: the closer arm takes the abuse instead of the door slamming into a wall or a separate stop. It's a stamped, heavy duty assembly meant for high volume traffic and potentially abusive installations. Whether you keep an existing wall or floor stop is a judgment call for your opening, but the arm is doing the stopping duty.
3) Can the hold-open on the Falcon SC70A-3049DS be turned off, or does the door hold open every time?
It's a manually selective hold-open. The user decides at the door whether to hold it open at the stop position or let it close normally, so the arm doesn't force a hold on every swing. That distinction matters on a fire rated opening, where a door that holds open every cycle is a problem.
4) Is the SC70A-3049DS a complete door closer or just the arm?
Arm only. The SC70A-3049DS is a replacement parallel arm assembly for an SC70A Series closer body you already have on the door. If your closer body itself is worn out, you're buying a complete closer, not this part. A full heavy duty closer with a parallel arm and compression stop already assembled would be something like the Sargent 25-CPS or the Sargent 1431-CPS TB EN, both Grade 1 heavy duty units.
5) What is the LCN equivalent of the Falcon SC70A-3049DS hold-open dead stop parallel arm?
The closest LCN counterpart by function is the LCN 1250-3049/PA hold open arm assembly with parallel arm shoe, a non-handed design with adjustable hold open for LCN 1250 Series closers. Both are non-handed hold-open parallel arm assemblies, but they differ in two ways that decide the order. The Falcon SC70A-3049DS is built for SC70A Series closers and uses a non-adjustable forearm with a positive mechanical stop, so the hold-open point is fixed by the arm. The LCN 1250-3049/PA has adjustable hold open, so the hold-open angle is set in the field. Match the arm to the closer body you already have on the door: the SC70A-3049DS mounts to SC70A Series closers, the 1250-3049/PA to the 1250 Series.
6) Is the Sargent 25-CPSH a substitute for the Falcon SC70A-3049DS?
They do the same job on the door but they are not interchangeable parts. The Sargent 25-CPSH is a heavy-duty hold-open parallel arm with compression stop for Sargent 351 and 281 door closers, and it is a Grade 1 heavy duty arm. The Falcon SC70A-3049DS is a hold-open dead stop parallel arm made for Falcon SC70A Series closers. Both give you hold-open plus a built-in stop in a parallel arm application, which is the usual answer for high volume traffic or potentially abusive installation conditions. The arm has to match the closer body it bolts to, so specify the 25-CPSH when the closer on the door is a Sargent 351 or 281 and the SC70A-3049DS when it is an SC70A.
7) I need a stop in the arm but I do not want the door holding open. What do I order instead of the SC70A-3049DS?
Drop the hold-open and keep the stop. The Sargent 25-CPS is a heavy duty parallel arm door closer arm with compression stop for 351 and 281 closers, Grade 1, and it stops the door without a hold-open feature. The Falcon SC70A-3049DS includes a manually selective hold-open along with its positive mechanical stop, which is what you do not want here. This matters in stairwells, smoke barriers and any opening where the door is not permitted to stand open. Check which closer body is on the door before ordering, since the 25-CPS is a Sargent 351/281 arm.
8) Is a parallel arm dead stop arm the right choice for a heavily used entrance, or should I use a regular arm?
For a high traffic or abuse-prone entrance, a parallel arm with a dead stop is the safer build. The arm mounts on the pull side of the frame so it tucks under the head and is less exposed to being grabbed or kicked, and the positive mechanical stop takes the over-travel load. The Falcon SC70A-3049DS is the stamped heavy duty version of that arm for SC70A Series closers. A regular arm projects out from the door and offers no built-in stop; LCN's 1260-3077 and 4000T-3077T are examples of standard and regular arm components, though those fit LCN closer bodies.
9) The opening has a wall stop already. Is there a hold-open arm without a dead stop?
Yes. The Sargent 25-H is a hold-open door closer arm for 351 and 281 closers in standard and top jamb mount, Grade 1 heavy duty, and it provides hold-open without a compression stop built into the arm. The Falcon SC70A-3049DS pairs its manually selective hold-open with a positive mechanical stop in the arm itself, which is the choice when nothing else on the opening stops the door. Where a floor or wall stop is already taking the impact, an arm-mounted stop is doing work twice. Note the mounting difference too: the SC70A-3049DS is a parallel arm assembly, while the 25-H is listed for standard and top jamb mount.
10) Will an LCN 1260-3077 or LCN 4000T-3077T arm work in place of the Falcon SC70A-3049DS?
No, and the reason is function before fit. The LCN 1260-3077 is a regular arm with parallel arm bracket assembly for 1260 Series closers, and the LCN 4000T-3077T is a standard arm replacement component for the 4000T Series. Neither is a hold-open arm and neither carries a stop. The Falcon SC70A-3049DS is a hold-open dead stop parallel arm with a manually selective hold-open and a positive mechanical stop. If the door currently holds open or is being stopped by the arm, a 3077 style regular or standard arm will not reproduce that behavior. Those arms are the right call only when you want plain closing with no hold-open and no arm-mounted stop, and the closer body matches the series.
11) What is the difference between the Falcon SC70A-3049DS and the LCN 4010-3049 hold open arm?
The LCN 4010-3049 is a hold open arm for door closers with an adjustable elbow function, catalogued in the 4020 Series. The Falcon SC70A-3049DS is a hold-open dead stop parallel arm for SC70A Series closers with a non-adjustable forearm assembly, so the geometry is fixed rather than set at the elbow during install. The fixed forearm gives consistent performance and eliminates field adjustment issues; the adjustable elbow on the 4010-3049 lets the installer tune the arm on site. Choose on the closer body and on whether you want that adjustment available to whoever services the door later.
12) The closer body is worn out too. Do I buy an arm or a complete closer?
If the closer body is failing, an arm alone will not fix the opening. The Sargent 1431-CPS TB EN is a complete heavy duty surface door closer with parallel arm and compression stop, Grade 1, so it replaces the body and the arm together in one part number. The Falcon SC70A-3049DS is a replacement arm assembly for SC70A Series closers, which is the right buy when the closer body is sound and the arm is bent, seized or missing its stop. On a rebuild or a facility standardization, the complete closer gets you a known configuration on every door; on a service call to a good body, the arm is the shorter job.
13) Is the Falcon SC70A-3049DS arm rated for commercial use or is it a residential part?
Commercial. The SC70A-3049DS is a commercial-duty door closer arm, and the stamped heavy duty build with a positive mechanical stop is aimed at schools, healthcare entrances, retail fronts, government buildings, and multi-tenant residential common doors. It isn't a light-duty residential closer part.
14) Does handing matter when cross-shopping hold-open parallel arms against the Falcon SC70A-3049DS?
Not for either of the two non-handed options. The Falcon SC70A-3049DS is a non-handed stamped assembly, so one part number covers left and right hand openings and you can stock a single arm across a building. The LCN 1250-3049/PA is likewise a non-handed design with adjustable hold open. For a property manager or MRO buyer carrying spares across a fleet of doors, that removes a stocking decision: the arm is chosen by closer series and finish, not by the swing of the door.
