    Sargent 25CPS EN – Frequently Asked Questions

    1) Will the Sargent 25-CPS arm fit my 351 Series door closer?
    Yes. The 25-CPS heavy duty parallel arm is built as an OEM replacement for Sargent 351, 281 and 1431 Series closers. If your closer body is one of those three series and it's mounted parallel arm (closer on the pull side, arm running parallel to the door face along the frame soffit), this is the correct arm assembly.
    2) What does the compression stop on this Sargent parallel arm actually do?
    It cushions the door at the end of the opening swing instead of letting it slam into a wall or over-travel and tear out the closer. The stop is built into the arm itself, so you are not adding a separate overhead stop or relying on a floor stop to protect the wall, frame and hardware. For high traffic openings where doors get thrown open, that's the main reason to spec the CPS arm over a plain parallel arm.
    3) Will this arm work if my closer is top jamb mounted instead of parallel arm?
    No. The 25-CPS is a parallel arm assembly and it needs a parallel arm application with the closer on the pull side and a soffit bracket on the frame. For a top jamb installation on a 351 Series closer you need the top jamb mounting plate instead, Sargent model 351A. Confirm which way the existing closer is mounted before ordering the arm.
    4) Can I put this Sargent arm on an LCN or Falcon closer?
    No. Closer arms are not cross-brand parts. The 25-CPS is cut for Sargent 351, 281 and 1431 Series bodies and the spline on the closer shaft will not match another manufacturer. For LCN bodies, ZenSupply stocks arms built to those series, including the LCN 1260-3077 regular arm with parallel arm bracket and the LCN 4000T-3077T standard arm. For Falcon 8200 Series operators there's the Falcon 8230-3077PLCM standard arm with track.
    5) I need a parallel arm that holds the door open rather than stopping it. What should I order?
    The Sargent 25-CPS uses a compression stop, which cushions and limits the opening swing to protect the wall and frame but does not hold the door open. For a hold open function you need a hold open arm matched to your closer brand and series: the Falcon SC60A-3049DS is a hold open dead stop parallel arm assembly for the SC60A Series, the Falcon SC70A-3049/PA is a hold open arm with PA bracket for the SC70A Series, the LCN 1250-3049/PA is a hold open arm assembly with parallel arm shoe for the 1250 Series, and the LCN 4010-3049 is a hold open arm with an adjustable elbow. Note that hold open arms are generally not permitted on fire rated openings without a listed release device.
    6) What is the closest equivalent to the Sargent 25-CPS parallel arm if the closer on the door is an LCN instead of a Sargent?
    The Sargent 25-CPS is a heavy duty parallel arm with an integrated compression stop built for Sargent 351, 281 and 1431 Series closers, so it is not a cross-brand part. On an LCN body, match the arm to the LCN series instead: the LCN 1250-3049/PA is a hold open arm assembly with a parallel arm shoe for the 1250 Series, and the LCN 1260-3077 is a regular arm with parallel arm bracket for the 1260 Series. Confirm the series number cast or labeled on the closer body before ordering, since closer arms are series specific.
    7) Our doors are center hung on floor pivots. Will the Sargent 25-CPS work there?
    No. The Sargent 25-CPS is a surface parallel arm for 351, 281 and 1431 Series surface closers, mounted to the push side of the frame. A center hung door running on a floor pivot with an overhead concealed closer uses a different assembly entirely, such as the Falcon OHC100A-DP center hung floor pivot with end load arm for OHC100 Series closers. Identify whether the closer is surface mounted on the door or concealed in the head frame before selecting an arm.
    8) Do I still need a separate door stop if I use this arm?
    The compression stop built into the 25-CPS arm handles the opening limit at the closer, so in most parallel arm installs it takes the place of a wall bumper or overhead stop for normal use. It cushions rather than hard-stops, which is what protects the closer body and frame from shock loading. On abuse-prone openings, many specs still pair a stop arm with a floor or wall stop as a backup, but the arm alone is what's doing the work here.
    9) Is this Sargent closer arm rated for a high traffic commercial opening?
    It's a Grade 1, heavy duty commercial component, not a residential part. Sargent builds it from commercial-grade materials for frequent-use openings, which is why it shows up in schools, hospitals, offices, government buildings and multi-tenant residential. For an MRO or institutional buyer standardizing on Grade 1 door control, this arm matches that spec level.
    10) What finishes does the Sargent 25-CPS parallel arm come in?
    Five sprayed enamel finishes: EAB sprayed brass enamel, EN sprayed aluminum enamel, EP sprayed bronze enamel to match satin bronze, EB sprayed bronze enamel to match dark satin bronze, and ED sprayed bronze enamel to match dark statuary bronze. If you're matching an existing closer on an adjacent door, pick the enamel code already on that closer body rather than matching by eye, since the three bronzes are close in appearance but keyed to different base finishes.
    11) My closer body is fine but the arm is bent, do I have to replace the whole closer?
    No. The 25-CPS is sold as a replacement arm assembly for 351, 281 and 1431 Series closers, so a bent or blown-out parallel arm can be changed out without pulling the closer body off the door. That's the usual repair after a door gets forced past its stop. Match the enamel finish code to the existing closer so the replacement doesn't stand out on the opening.
    12) Is a standard arm a cheaper alternative to the 25-CPS on the same door?
    They do different jobs. The Sargent 25-CPS is a parallel arm with an integrated compression stop, meaning it both mounts on the push side under the frame soffit and limits the opening swing. A standard arm such as the LCN 4000T-3077T for the 4000T Series or the Falcon 8230-3077PLCM standard arm with track for the 8230 Series automatic operators does not provide a built in stop, so an opening with no floor or wall stop would let the door overswing into the wall. Choose a plain arm only where a separate overhead or floor stop is already controlling the swing.
    13) What looks like a substitute for the 25-CPS but will not actually fit?
    The parts most often mistaken for it are other brands' parallel arm kits. A Falcon SC60A-3049DS or SC70A-3049/PA is a parallel arm but is built for Falcon SC60A and SC70A Series bodies, and the LCN 1250-3049/PA and LCN 1260-3077 are built for LCN 1250 and 1260 Series bodies. The Sargent 25-CPS pinion socket and shoe are cut for Sargent 351, 281 and 1431 Series closers, so none of those cross over even though the mounting concept is the same. Match the arm to the closer body's own series every time.
    14) Does replacing the arm affect ADA opening force compliance?
    The arm supports accessibility compliance when it's paired with a compatible closer, but the opening force is set by the closer body spring size and the valve adjustments, not by the arm. Swapping in the 25-CPS won't change your force reading on its own. After installation, re-check opening force and closing sweep and latch timing at the closer and adjust there.
