    Sargent 25UH EN – Frequently Asked Questions

    1) Which Sargent door closers does the 25-UH hold-open arm fit?
    The 25-UH universal hold-open arm is built for Sargent 351, 281, and 1431 Series closers. It is a replacement arm only, not a complete closer, so the closer body on the door has to be one of those three series for it to go on.
    2) Can I use this Sargent arm for a parallel arm installation, or is it standard mount only?
    All three. The 25-UH covers parallel arm, standard (regular) mount, and top jamb applications, which is what the universal designation refers to. Parallel arm puts the arm on the push side under the frame soffit, regular mount on the pull side, top jamb on the push side of the frame face. Pick the configuration that matches how the closer body is already mounted.
    3) My closer is an LCN, not a Sargent. Can I put the 25-UH arm on it?
    No. The 25-UH is matched to Sargent 351, 281, and 1431 closer bodies, and closer arms are not interchangeable between manufacturers because the pinion spline and shoe differ. For LCN bodies, use the LCN arm for that series, such as the 1250-3049/PA hold open arm with parallel arm shoe for 1250 Series closers, or the 4010-3049 hold open arm.
    4) What is the LCN equivalent of the Sargent 25-UH hold-open closer arm?
    The closest LCN counterpart is the LCN 1250-3049/PA, a hold open arm assembly with parallel arm shoe in a non-handed design with adjustable hold open. The Sargent 25-UH is a universal hold-open arm for Sargent 351, 281 and 1431 Series closers covering parallel arm, standard and top jamb mounting. The LCN part is built for LCN 1250 Series closers, so it is an equivalent function rather than a part that drops onto a Sargent closer body.
    5) Will a standard arm like the LCN 4000T-3077T work if I want hold-open?
    No. 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 - neither provides hold-open. For a door that must stay open at a preset angle and then close under control, use a hold-open arm such as the Sargent 25-UH on Sargent 351, 281 or 1431 Series closers.
    6) Can the Sargent 25-UH arm be used on an automatic door operator or a center hung floor pivot door?
    No. The Sargent 25-UH is a manual hold-open arm for Sargent 351, 281 and 1431 Series surface closers in parallel, standard and top jamb mounts. For an automatic operator, the Falcon 8230-3077PLCM is a standard arm with track for 8230 Series automatic door operators; for a center hung pivot application, the Falcon OHC100A-DP is a center hung floor pivot with end load arm for OHC100 Series closers.
    7) Do I need a separate mounting plate for a top jamb installation with this Sargent arm?
    For top jamb work Sargent offers the 351A top jamb mounting plate as a companion part. The 25-UH arm itself does not include it, so if your frame face needs a plate, order the 351A along with the arm.
    8) Is this Sargent arm heavy duty enough for a school or hospital entrance?
    It is a Grade 1, heavy duty commercial component, which is the top ANSI/BHMA grade tier for door hardware and the level normally specified for schools, hospitals, and other high-traffic institutional openings. It is not a residential-duty part.
    9) What does the hold-open function on this closer arm actually do?
    The arm holds the door open at a preset angle so it stays put for loading, moving, or accessibility, then closes under the closer's control once the door is pushed past the hold point. Note that hold-open arms are not used on fire-rated openings unless the hold-open is electrically released, so check the opening before you fit one.
    10) I need a hold-open parallel arm with a dead stop. Does the Sargent 25-UH give me that?
    The 25-UH provides hold-open in parallel, regular, and top jamb mounting, but it is not described as a dead stop arm. If you need the arm itself to stop the door and protect the wall, the Falcon SC60A-3049DS is a hold-open dead stop parallel arm assembly, built for SC60A Series closers. Match the arm to whatever closer body is on the door.
    11) Will swapping in this hold-open arm keep my door ADA compliant?
    The arm supports accessibility compliance when it is paired with a compatible Sargent closer, but compliance comes from the closer's opening force and closing speed adjustments, not from the arm. Replacing a worn arm restores correct geometry; you still set sweep, latch, and spring power at the closer body.
    12) Is the Sargent 25-UH a genuine OEM replacement or an aftermarket copy?
    It is a Sargent part built to match original equipment fit and performance on 351, 281, and 1431 Series closers, so it goes back on an existing installation without modifying the closer body or the door prep.
