    Sargent 25PS EB – Frequently Asked Questions

    1) Will the Sargent 25-PS arm fit my existing door closer?
    The 25-PS parallel arm with positive stop is built as an OEM replacement for Sargent 351, 281 and 1431 Series closers. If your closer body is one of those three series, it drops in. It is not intended for closers outside those series, so confirm the series stamped on your closer body before ordering.
    2) What does the positive stop on this Sargent closer arm actually do?
    The integrated positive stop limits how far the door can swing open, so the door leaf and closer stop short of hitting a wall, railing or adjacent structure. That is the reason to choose the 25-PS over a plain parallel arm: in a corridor or vestibule where there is no wall stop or floor stop, the arm itself takes the job. Note it is a stop, not a hold-open, so the door still closes under the closer's control.
    3) I need a hold-open arm, not a positive stop. What else do you carry?
    The 25-PS stops the swing but does not hold the door open. For hold-open you need a different arm matched to your closer brand and series: the Falcon SC60A-3049DS hold-open dead stop parallel arm assembly for SC60A closers, the Falcon SC70A-3049/PA hold open arm with PA bracket for SC70A closers, the LCN 1250-3049/PA hold open arm with parallel arm shoe, or the LCN 4010-3049 hold open arm with adjustable elbow. Arms are series specific, so match the series on your closer body.
    4) Can I use this Sargent arm on an LCN or Falcon closer?
    No. Closer arms are not cross-brand parts. The 25-PS is cut for Sargent 351, 281 and 1431 Series bodies. For an LCN body, look at the matching LCN component, such as the 1260-3077 regular arm with parallel arm bracket or the 4000T-3077T standard arm. For a Falcon body, the 8230-3077PLCM arm with track suits the 8200 Series operators.
    5) What is the closest parallel arm equivalent to the Sargent 25-PS from another manufacturer?
    For a parallel arm assembly with a stop built into the arm, the Falcon SC60A-3049DS is the nearest counterpart - it is a hold-open dead stop parallel arm assembly for the SC60A Series. The Sargent 25-PS is a heavy duty parallel arm with positive stop for Sargent 351, 281 and 1431 Series closers, so the two are not interchangeable across closer bodies: each arm mates to its own closer series. Choose the 25-PS when the body on the door is a Sargent 351, 281 or 1431, and the SC60A-3049DS when the body is a Falcon SC60A.
    6) I need hold-open rather than just a positive stop - what arm should I use instead?
    The Sargent 25-PS provides a positive stop to control door swing, not an adjustable hold-open. If the opening needs to stay parked open, the LCN 1250-3049/PA is a hold open arm assembly with a parallel arm shoe and a non-handed design with adjustable hold open, and the LCN 4010-3049 is a hold open arm with an adjustable elbow function. Both are tied to their own closer series - 1250 Series and 4020 Series respectively - so the closer body on the door dictates which one fits.
    7) Can the Sargent 25-PS replace the arm on an automatic door operator or an overhead concealed closer?
    No. The Sargent 25-PS is a surface parallel arm for Sargent 351, 281 and 1431 Series closers. An automatic operator takes its own arm - the Falcon 8230-3077PLCM is a standard arm with track for 8230 Series automatic door operators. An overhead concealed application is different again: the Falcon OHC100A-DP is a center hung floor pivot with end load arm for OHC100 Series door closers. Match the arm to the operator or closer family already in the header or door.
    8) Parallel arm vs regular arm on a door closer, which do I need?
    Parallel arm mounting puts the closer on the pull side of the door with the arm running back along the door face, which keeps the arm tucked in tight and out of traffic, and it is the usual choice on exterior doors and high abuse openings. A regular arm projects out from the frame on the push side. The 25-PS is a parallel arm assembly only, so it suits a pull-side mount. If your closer is mounted top jamb on the push side, you need the top jamb hardware instead, such as the Sargent 351A top jamb mounting plate.
    9) Is this Sargent arm heavy duty enough for a school or hospital entry?
    Yes. The 25-PS is rated Heavy Duty and Grade 1, and it is a commercial-only component, which is the level specified for high traffic openings in schools, hospitals, offices and government buildings. Grade 1 is the top ANSI/BHMA performance tier for door hardware.
    10) My closer arm is bent and the door slams into the wall. Is the whole closer shot?
    Usually not. On parallel arm installs the arm is the sacrificial part, and the 25-PS is sold as a standalone OEM replacement for Sargent 351, 281 and 1431 Series closers, so a bent arm or a failed stop can be swapped without pulling the closer body off the door. Keep the same finish code and the repair is invisible.
    11) Is this arm handed, or does one part cover both left and right doors?
    The 25-PS is a parallel arm assembly for Sargent 351, 281 and 1431 Series closers and is ordered by finish only, with no handing option on the order. Mounting hand is set by how the closer body and arm shoe are positioned on the door, not by a separate part number.
    12) What is the simpler option if I do not need the stop feature in the arm?
    A plain standard or regular arm covers openings where a wall or floor stop already limits the swing. The LCN 4000T-3077T is a standard arm replacement component for the 4000T Series, and the LCN 1260-3077 is a regular arm with parallel arm bracket for the 1260 Series. The Sargent 25-PS is the choice when you want the stop integrated in the arm itself to protect walls and adjacent structures, and it fits Sargent 351, 281 and 1431 Series closers.
    13) My closer is mounted top jamb, not parallel arm - is the 25-PS still the right part?
    The Sargent 25-PS is built for parallel arm applications, where the arm runs back along the face of the door. A top jamb installation is a different mounting, and the Sargent 351A Top Jamb Mounting Plate is the companion part for that setup. If you are buying a hold-open arm for a top jamb or parallel conversion on a Falcon body instead, the SC70A-3049/PA is a hold open arm supplied with a PA bracket for SC70A Series closers.
    14) For a high-traffic school or hospital opening, which arm holds up and does the 25-PS carry a grade?
    The Sargent 25-PS is a Grade 1, heavy duty commercial arm, which is the tier institutional facilities standardize on for schools, hospitals and other high-traffic openings. Among the alternatives, the Falcon SC60A-3049DS also gives a dead stop in a parallel arm assembly and the LCN 1250-3049/PA adds adjustable hold open, so the decision usually comes down to which closer body is already installed rather than duty level.
    15) What finishes does the Sargent 25-PS parallel arm come in?
    Five sprayed enamel finishes: EAB sprayed brass, EN sprayed aluminum, EB sprayed bronze to match dark satin bronze, ED sprayed bronze to match dark statuary bronze, and EP sprayed bronze to match satin bronze. If you are matching an arm to closers already hung in the building, pick the enamel code that matches the closer body rather than guessing from the door finish, since the three bronzes are visibly different shades.
    16) Does replacing the arm affect ADA opening force compliance on my door?
    The arm itself does not set opening force; the closer body and its spring size do. The 25-PS supports accessibility compliance when it is paired with a compatible Sargent closer, but you still adjust and verify opening force at the closer after the arm is installed.
