LCN 4030-3077LD 652 – Frequently Asked Questions

1) Do I need to order a left-hand or right-hand version of the LCN 4030-3077LD closer arm?
Neither. The 4030-3077LD light duty arm is non-handed, so the same part installs on a left-hand or right-hand door with no modification. For a property manager stocking spares across a building, that means one part number covers every opening running a 4030 Series closer.
2) Will the 4030-3077LD arm work for a parallel arm mount, or only regular arm?
It covers hinge (regular) side, top jamb, and parallel arm mounting. For parallel arm applications you also have to order the 62PA bracket, which is not part of the arm itself. If you are replacing a closer arm that was mounted on the push side of the door under the frame soffit, plan on the 62PA going in the same order.
3) Which LCN door closers does the 4030-3077LD light duty arm fit?
It is built for LCN 4030 Series surface closers. It is a genuine LCN replacement component for that series, so it is the part to order when the original arm on a 4030 closer is bent, seized, or missing. It is not sold as a fit for other closer families.
4) I need a hold-open arm instead of a standard closer arm - what are my options?
The LCN 4030-3077LD is a light duty replacement arm for 4030 Series door closers and does not provide hold-open. If the opening needs to stay open, Sargent offers the 25-H hold-open door closer arm for 351 and 281 closers in standard and top jamb mount, and the 25-CPSH heavy-duty hold-open parallel arm with compression stop for the same closer families. Falcon's SC70A-3049/PA is a hold open arm supplied with a PA bracket for SC70A Series closers, and the SC60A-3049DS is a hold-open dead stop parallel arm assembly. All of these are tied to their own closer series, so match the arm to the closer body already on the door rather than to the mounting style alone.
5) Will a Sargent 25-CPS arm work on an LCN 4030 closer?
No. The Sargent 25-CPS is a heavy duty parallel arm with compression stop built for Sargent 351 and 281 closer bodies, while the LCN 4030-3077LD arm is engineered specifically for 4030 Series closers. Closer arms interface with the spindle and mounting prep of their own manufacturer's body, so they are not interchangeable across brands. If the closer on the door is an LCN 4030, order the 4030-3077LD; if it is a Sargent 351 or 281, the 25 series arms are the correct family.
6) Is a light duty arm the right choice for a high-traffic entrance door?
The 4030-3077LD is the light duty arm, which means it has no dead stop or hold-open built into it. On an exterior or high-abuse opening where the arm is taking stop loads, a heavy duty arm with a compression stop is the better call, for example the Sargent 25-CPS or the 1431-CPS TB EN, both Grade 1 heavy duty. Use the light duty arm where the door has its own wall or floor stop and the arm is only controlling the swing.
7) Does replacing the arm affect ADA door closer compliance?
No. Installed correctly on a compatible 4030 Series closer, the arm maintains ADA compliant operation. It is a commercial-grade component, so the closer's opening force behavior is restored rather than compromised by using it.
8) Can I use this arm to convert a hinge-side mounted 4030 closer to parallel arm on the push side?
Yes, the arm itself supports parallel arm mounting, but the conversion also needs the 62PA parallel arm bracket. Without that bracket the arm can only be run hinge side or top jamb. Order both together if you are changing the mounting condition rather than just swapping a damaged arm.
9) What is the difference between ordering a replacement arm and ordering a complete closer?
The LCN 4030-3077LD is a replacement part only - the light duty arm that connects a 4030 Series closer body to the frame or door. It restores an existing installation and carries no spring power or hydraulic function of its own. If the closer body itself is failing, a complete unit is the right buy: the Sargent 1431-CPS TB EN is a heavy duty Grade 1 surface door closer supplied with a parallel arm and compression stop, and the Sargent 25-CPS covers the heavy duty parallel arm side for 351 and 281 bodies. Buy the arm when the body is sound; buy the closer when it is not.
10) My opening is a center hung door on a floor pivot - can I use this arm?
No. The LCN 4030-3077LD light duty arm is for surface mounted 4030 Series closers mounted hinge side, top jamb, or parallel arm on a standard swing door. A center hung door running on a floor pivot needs pivot-specific hardware such as the Falcon OHC100A-DP, a center hung floor pivot with end load arm for OHC100 Series closers. The two address different door hanging methods, not different duty levels.
11) Is a light duty arm enough for a high-traffic entrance, or should I specify heavy duty?
The LCN 4030-3077LD is a light duty arm for commercial 4030 Series closers and suits standard interior commercial openings. Where abuse is expected - a main entrance, a school corridor, a loading area - the heavy duty arm families are the ones to spec: Sargent's 25-CPS and 25-CPSH are both rated heavy duty and Grade 1, as is the 25-H hold-open arm. Those are Sargent 351/281 components, so switching duty level in practice means matching the closer body as well as the arm.
12) The door has an automatic operator on it - will this replacement arm fit?
No. The LCN 4030-3077LD serves manual 4030 Series surface door closers. An automatic operator uses its own arm and track assembly, such as the Falcon 8230-3077PLCM standard arm with track for 8230 Series automatic door operators. Confirm whether the head unit is a manual closer or a powered operator before ordering, because the arm geometry and attachment differ between the two.
13) Do any of the alternative arms come with the parallel mounting bracket included?
With the LCN 4030-3077LD, parallel arm mounting is possible but calls for the 62PA bracket in addition to the arm. Falcon's SC70A-3049/PA is supplied as a hold open arm with its PA bracket for SC70A Series closers, and the Sargent 25-CPS and 25-CPSH are parallel arm assemblies for 351 and 281 closers. If you want a single line item that lands parallel-mounted, those are the ones to look at; if the closer on the door is a 4030, add the 62PA to the arm order.
14) What finishes can I get the 4030 light duty closer arm in to match my other door hardware?
Thirteen finishes: 616 satin bronze blackened, 632 bright brass, 633 satin brass, 639 satin bronze, 646 satin nickel, 651 bright chrome, 652 satin chrome, 689 aluminum, 690 statuary bronze, 691 light bronze, 693 gloss black, 695 dark bronze, and 696 brass. 689 aluminum and 695 dark bronze are the two you will most often be matching on existing commercial openings.
15) Is this a genuine LCN part or an aftermarket copy?
Genuine LCN. It is the factory replacement arm for the 4030 Series, which matters on institutional work where the specification calls out LCN by name and a substituted arm can void the closer's original performance on the opening.
