    Sargent 25HZ EAB – Frequently Asked Questions

    1) What is the Sargent 25-HZ arm and when do I need it instead of a standard closer arm?
    The 25-HZ is a hold-open replacement arm for Sargent door closers built for deep reveals, covering reveal depths from 2-1/8 inches up to 5 inches. On a standard arm the reveal is too deep and the arm simply won't reach the door in a top jamb application. If your frame face sits back that far from the door, this is the arm that spans it while still giving you a hold-open at a selected angle.
    2) Which Sargent door closers does the 25-HZ arm fit?
    It's made for Sargent 351, 281, and 1431 Series closers as an OEM replacement arm. If your closer body is from another series or another brand, don't order it; the arm mounts to the closer's spindle and the bracket geometry is series-specific.
    3) My reveal is only about an inch deep. Will this arm still work?
    No. The 25-HZ starts at a 2-1/8 inch reveal, so on a shallow reveal it's the wrong part. For shallower conditions you want the standard hold-open arm for your 351, 281, or 1431 closer rather than the deep-reveal version.
    4) I need a hold-open arm but my closer is an LCN or Falcon, not a Sargent. What's the equivalent?
    The 25-HZ only fits Sargent 351, 281, and 1431 closers, so match the arm to your closer brand and series instead. For LCN, the 1250-3049/PA hold open arm with parallel arm shoe covers 1250 Series closers and the 4010-3049 hold open arm with adjustable elbow covers the 4020 Series. On the Falcon side, the SC70A-3049/PA hold open arm with PA bracket suits SC70A Series closers and the SC60A-3049DS is a hold-open dead stop parallel arm assembly.
    5) What is the LCN equivalent of a Sargent 25-HZ hold-open closer arm?
    The closest LCN counterparts are hold-open arm assemblies built for LCN's own closer families: the LCN 1250-3049/PA hold open arm assembly with parallel arm shoe, a non-handed design with adjustable hold open, and the LCN 4010-3049 hold open arm with adjustable elbow function for the 4020 Series. Both deliver hold-open at the arm the way the Sargent 25-HZ does, but the 25-HZ is built to mate with Sargent 351, 281 and 1431 Series closers, so an LCN arm is an equivalent only if the closer body on the door is LCN.
    6) What should I use if I do not need hold-open, just a standard closer arm?
    Hold-open is the whole point of the Sargent 25-HZ, which stops the door at a selected angle until released. If the opening should always self-close - a fire-rated or smoke-barrier door, for instance - use a plain regular or standard arm instead, such as the LCN 1260-3077 regular arm with parallel arm bracket or the LCN 4000T-3077T standard arm replacement component, matched to the closer series already mounted.
    7) My frame reveal is deeper than a standard arm can reach - is there an alternative to the 25-HZ?
    The Sargent 25-HZ is the arm specifically engineered for deep reveals from 2-1/8 inch to 5 inch, where standard arms cannot reach, and it suits both regular and top jamb mounting. Comparable hold-open arms such as the Falcon SC60A-3049DS dead stop parallel arm assembly and the LCN 1250-3049/PA parallel arm assembly are parallel-arm designs tied to their own closer series rather than deep-reveal solutions, so on a deep reveal with a Sargent 351, 281 or 1431 closer the 25-HZ is the arm that addresses the condition.
    8) Can I use the 25-HZ arm in a top jamb mount, or is it regular mount only?
    Both. The arm works in standard mount and in top jamb applications. For top jamb work, the Sargent 351A top jamb mounting plate is the companion piece, and it is a separate item from the arm itself.
    9) Is this arm heavy enough for a school or hospital corridor door?
    It's a Grade 1, heavy duty commercial component, which is the top ANSI/BHMA duty tier and what's normally specified for high-traffic institutional openings like schools, hospitals, and government buildings.
    10) Do I need to order anything else to replace a deep-reveal arm on a top jamb mounted Sargent closer?
    For a top jamb installation, the Sargent 351A top jamb mounting plate is the related component to have on hand along with the arm. On a straight arm-for-arm swap where the existing bracket and plate are sound, the arm alone does the job.
    11) I want hold-open and a built-in stop so the door cannot swing into a wall - which arm does that?
    For a stop function integrated into the arm, the Falcon SC60A-3049DS is a hold-open dead stop parallel arm assembly for the SC60A Series - it combines hold-open with a dead stop. The Sargent 25-HZ provides hold-open at a preset angle for deep reveals of 2-1/8 inch to 5 inch on Sargent 351, 281 and 1431 Series closers; if you also need a stop on a Sargent opening, pair it with a separate overhead or floor stop.
    12) Which of these hold-open arms is non-handed?
    The LCN 1250-3049/PA is described as a non-handed design with adjustable hold open, so one part covers left and right hand openings. The Sargent 25-HZ is ordered by finish only - EAB sprayed brass enamel, EB and ED and EP sprayed bronze enamels, and EN sprayed aluminum enamel - and is matched to the Sargent 351, 281 or 1431 closer it serves rather than to a handing option.
    13) Is a track arm or an operator arm a substitute for the 25-HZ?
    No. The Falcon 8230-3077PLCM is a standard arm with track for 8230 Series automatic door operators, and the Falcon OHC100A-DP is a center hung floor pivot with end load arm for OHC100 Series closers - both belong to entirely different closer architectures. The Sargent 25-HZ is a surface closer arm for Sargent 351, 281 and 1431 Series bodies, with hold-open built into the arm itself.
    14) Will swapping in this arm keep my door ADA compliant?
    The arm supports accessibility requirements when it's paired with a compatible door closer, but compliance comes from the closer's opening force and closing speed adjustment, not the arm. Replacing a damaged arm on a 351, 281, or 1431 closer restores the original geometry; you'd still set the closer's force and sweep to your accessibility requirement after install.
