Falcon SC70A-3077DS AL – Frequently Asked Questions

1) Do I need to order a left-hand or right-hand version of the SC70A-3077DS parallel arm?
Neither. The 3077DS is non-handed, so the same arm goes on a left-hand or right-hand door. One part number covers both swings, which is why it's the one to stock if you're carrying spares for a building with doors going both ways.
2) What does the DS in SC70A-3077DS mean, and do I still need a floor or wall stop?
DS is dead stop: the arm carries a positive mechanical stop built into the assembly, so the door stops at a fixed open position rather than swinging into the wall behind it. That's the point of the part in abuse-prone openings. It's a stop in the arm, not an adjustable hold-open, so the door still closes on its own. If you want the door to stay open, that's a hold-open arm instead, like the Sargent 25-CPSH or the LCN 1250-3049/PA.
3) What is the LCN equivalent of the Falcon SC70A-3077DS dead stop parallel arm?
The closest LCN part by function is the LCN 1260-3077, a regular arm with parallel arm bracket door closer assembly for the LCN 1260 Series. Both are arm assemblies rather than complete closers, and both carry the 3077 arm designation. The difference that matters for a locksmith at the door: the Falcon SC70A-3077DS carries a positive mechanical stop in a non-adjustable, stamped heavy-duty forearm, while the LCN 1260-3077 is described as a regular arm with a parallel arm bracket. Each arm is built for its own closer body, so match the arm to the closer already mounted on the door: the SC70A-3077DS to a Falcon SC70A Series closer, the 1260-3077 to an LCN 1260 Series closer.
4) I need the door to hold open, not dead stop. What arm should I use instead of the SC70A-3077DS?
The SC70A-3077DS is a dead stop arm: it provides a positive mechanical stop that prevents over-travel, and it does not hold the door open. For a hold-open opening, the LCN 1250-3049/PA is a hold open arm assembly with parallel arm shoe, non-handed, with adjustable hold open, for the LCN 1250 Series. The LCN 4010-3049 is a hold open arm with adjustable elbow function. On the Sargent side, the 25-CPSH is a heavy-duty hold-open parallel arm with compression stop for 351 and 281 closers, which gives both hold open and a stop in one arm, and the 25-H is a hold-open arm for 351 and 281 closers in standard and top jamb mount. Choose by the closer body on the door, since none of these arms crosses to a Falcon SC70A Series closer.
5) Can I adjust the forearm length on the Falcon 3077DS to dial in the door's stop angle?
No. The 3077DS uses a non-adjustable forearm assembly, so the stop angle is fixed by the arm and the shoe location on the frame. That's deliberate on abuse openings, since there's no adjustment for someone to back off or knock loose. If you need to tune the open angle after install, use an adjustable-elbow arm such as the LCN 4010-3049 on an LCN closer instead.
6) Is a dead stop arm the right choice for a school or hospital entrance, or should I use a regular arm?
Dead stop is the one for heavy traffic and openings that take abuse. A regular arm, like the LCN 4000T-3077T standard arm, just controls the swing and leaves the stopping to a floor or wall stop, so anyone who throws the door open drives it into whatever's behind it. The 3077DS is stamped heavy-duty with the stop in the arm, which is why it goes on high volume commercial, school, healthcare and municipal doors. If there's already a good wall stop and the traffic is light, a regular arm is enough.
7) My closer body is fine but the arm is bent. Can I just replace the arm on a Falcon SC70A?
Yes, that's exactly what the SC70A-3077DS is for. It's a replacement parallel arm assembly for SC70A closers, so a bent or torn-off arm doesn't cost you the whole closer. Follow the closer's own installation instructions when you fit it, since the shoe position on the frame sets where the door stops.
8) My spec calls for a Grade 1 door control. Does the Falcon SC70A-3077DS arm meet that, or do I need Sargent?
Grade 1 is stated for the Sargent parts in the comparable range - the 1431-CPS TB EN, 25-CPS, 25-CPSH and 25-H are all Grade 1, heavy duty. The Falcon SC70A-3077DS is a commercial-duty replacement arm whose grade follows the SC70A Series closer it is installed on, since a grade is certified for the closer assembly and not for a loose arm. For an institutional submittal, the practical route is to grade the closer: specify the Sargent 1431-CPS TB EN if the opening needs a complete Grade 1 surface closer with parallel arm and compression stop, or cite the SC70A Series closer already installed and order the SC70A-3077DS as its service arm.
9) The opening has a wall stop already and does not need a stop in the arm. What is the alternative to the SC70A-3077DS?
Where a floor or wall stop already controls the door swing, a plain arm without an integral stop does the job. The LCN 4000T-3077T is a standard arm replacement component for the LCN 4000T Series, and the LCN 1260-3077 is a regular arm with parallel arm bracket for the 1260 Series. The Falcon SC70A-3077DS is the choice when the stop has to live in the arm, since its positive mechanical stop protects the door and frame in high volume traffic and potentially abusive conditions where a separate stop can be defeated or is not present. As always, the arm has to match the closer series on the door.
10) Which arms are non-handed, so I can stock one part for both left-hand and right-hand doors?
For a property manager standardizing a parts shelf, the Falcon SC70A-3077DS is non-handed and installs on both left-hand and right-hand applications. The LCN 1250-3049/PA is also a non-handed design, with an adjustable hold open and a parallel arm shoe. Non-handed means one shelf part covers every door of that closer series in the building, so the handing question moves off the order form entirely. The remaining decision is still the closer series: the SC70A-3077DS goes on Falcon SC70A Series closers and the 1250-3049/PA on LCN 1250 Series closers.
11) I need a top jamb mount, not parallel arm. Can the SC70A-3077DS be used?
The SC70A-3077DS is a parallel arm assembly, mounted on the pull side with the arm running along the face of the door. 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. Confirm the mounting orientation on the drawing before ordering, because a parallel arm and a top jamb arm land in different positions on the frame and the prep does not transfer between them.
12) What is the difference between an adjustable arm like the LCN 4010-3049 and the non-adjustable Falcon SC70A-3077DS?
The LCN 4010-3049 is a hold open arm with an adjustable elbow function, so the hold-open point can be set in the field. The Falcon SC70A-3077DS uses a non-adjustable forearm assembly, a fixed configuration that eliminates tampering and holds consistent operation in challenging installations. On a school corridor or a public entrance where residents or students reach the hardware, the fixed forearm keeps the setting where the installer left it; where an opening needs its stop or hold-open point tuned after hanging, an adjustable arm is the one that allows it.
13) Is the 3077 in the Falcon SC70A-3077DS the same arm as the LCN 3077 arms?
The 3077 number appears in both catalogs - the LCN 1260-3077 is a regular arm with parallel arm bracket for the 1260 Series and the LCN 4000T-3077T is a standard arm for the 4000T Series - but a shared arm number across two manufacturers does not make the parts interchangeable. The Falcon SC70A-3077DS is engineered for the Falcon SC70A Series closer, and the DS suffix marks the dead stop version with the positive mechanical stop. For a distributor pulling stock, the closer series prefix is the identifying element, not the 3077: SC70A-3077DS, 1260-3077 and 4000T-3077T each serve their own closer body.
14) Do the alternatives to the Falcon SC70A-3077DS come in matte black or dark bronze?
The Falcon SC70A-3077DS dead stop parallel arm is offered in 689 aluminum, 696 brass, 695 dark bronze and 622 matte black, so it can be matched to storefront and interior hardware without a field finish. Finish options are not part of what the comparable LCN and Sargent arms state, so where a finish has to match across a run of doors, the SC70A-3077DS with its four listed finishes is the arm to specify against the Falcon SC70A Series closers on those openings.
