    Sargent 25SP10 EAB – Frequently Asked Questions

    1) Which Sargent door closers does the 25-SP10 security arm fit?
    The 25-SP10 heavy duty parallel security arm is built as the OEM replacement arm for Sargent 351, 281 and 1431 Series closers. If your closer body is from another Sargent family or another brand, this is not the arm for it.
    2) Can I use the Sargent 25-SP10 arm on a regular arm (pull side) closer installation?
    No. The 25-SP10 is a parallel arm configuration, so it mounts on the push side of the opening with the closer body on the door and the shoe on the frame soffit. For a top jamb mount on a 351 closer you need the mounting plate instead, model 351A.
    3) Is the Sargent 25-SP10 a hold-open arm?
    No hold-open function. The 25-SP10 is a security arm, meaning heavier construction for tamper and forced-entry resistance in high abuse openings, with normal closing action. If you want hold-open on a parallel mount, that is a different arm type, for example the Falcon SC60A-3049DS hold-open dead stop parallel arm assembly or the LCN 1250-3049/PA hold open arm with parallel arm shoe, each for its own closer series.
    4) Will an LCN or Falcon parallel arm fit a Sargent 351 closer instead of the 25-SP10?
    No. Arms are series-specific. The Sargent 25-SP10 is cut for Sargent 351, 281 and 1431 Series closer bodies as an OEM replacement. The LCN 1260-3077 regular arm with parallel arm bracket is for the LCN 1260 Series, the LCN 4000T-3077T standard arm is a 4000T Series component, and the Falcon SC70A-3049/PA hold open arm with PA bracket is for Falcon SC70A Series closers. If the body on the door is a Sargent 351, 281 or 1431, the 25-SP10 is the arm that lands on the spindle correctly.
    5) Is there a hold-open parallel arm I can use instead of the Sargent 25-SP10 when the opening needs to stay propped?
    The Sargent 25-SP10 is a heavy duty parallel security arm built for the Sargent 351, 281 and 1431 Series closers, and it is a security arm rather than a hold-open. If the door needs to stay propped, the Falcon SC60A-3049DS is a hold-open dead stop parallel arm assembly for the Falcon SC60A Series, and the LCN 1250-3049/PA is a hold-open arm assembly with a parallel arm shoe using a non-handed design with adjustable hold open on LCN 1250 Series closers. Each of those arms goes with its own closer body, so the hold-open route means matching the arm to the closer brand and series already on the door.
    6) Why would I pay for a security arm instead of a standard parallel arm on a school or detention door?
    Abuse. The security arm uses heavier construction to resist tampering and forced entry, which is why it gets specified on schools, correctional facilities and government buildings where a standard arm is the first thing that gets attacked or bent. On a normal office interior door a standard arm is enough.
    7) Is the Sargent 25-SP10 arm Grade 1?
    Grade 1, heavy duty, and rated for commercial use. That is the duty level facilities buyers standardize on for high-traffic openings.
    8) What finishes does the Sargent 25-SP10 security arm come in, and how do I match my existing closers?
    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. Order the same finish code stamped on the closers already on your other openings so the replacement arm blends in.
    9) My closer is center hung on a floor pivot - is the Sargent 25-SP10 the right arm?
    No. The Sargent 25-SP10 is a parallel arm configuration, meaning it mounts on the push side with the arm running parallel to the door face. A center hung floor pivot opening takes different hardware entirely - the Falcon OHC100A-DP is a center hung floor pivot with end load arm for OHC100A Series overhead concealed closers. Confirm the mounting condition first: parallel arm surface closer versus center hung concealed decides the part before brand does.
    10) For a school or correctional door, what is the difference between the Sargent 25-SP10 and a standard replacement arm?
    The Sargent 25-SP10 is a heavy duty, Grade 1 commercial security arm whose enhanced strength construction adds tamper resistance for high-risk environments such as schools, correctional facilities and government buildings. A standard arm such as the LCN 4000T-3077T is a plain standard arm replacement component for the 4000T Series, and the Falcon 8230-3077PLCM is a standard arm with track for 8230 Series automatic door operators. Those are general duty replacements for their own closer families; the 25-SP10 is the choice when the abuse and tamper exposure on the opening is the deciding factor.
    11) What is the closest LCN equivalent to the Sargent 25-SP10 if the building standardizes on LCN?
    There is no cross-brand drop-in for a Sargent arm, but within LCN the comparable parallel arm parts are the 1260-3077 regular arm with parallel arm bracket for 1260 Series closers, the 4010-3049 hold open arm with adjustable elbow function, and the 1250-3049/PA hold open arm assembly with parallel arm shoe for 1250 Series. Going LCN on an opening that currently has a Sargent 351, 281 or 1431 means changing the closer body as well as the arm, since each arm mates only to its own series.
    12) Will swapping in this arm affect ADA opening force compliance?
    The arm itself does not set opening force; that comes from the closer's spring size and valve adjustment. The 25-SP10 works with ADA-compliant configurations when paired with the appropriate Sargent 351, 281 or 1431 closer, so set the closer per its own instructions after the arm is on.
    13) Where do I find the mounting dimensions and templates for the Sargent 25-SP10 arm?
    Mounting and template data for the 351, 281 and 1431 parallel arm applications is in the SARGENT Full Line Catalog, published at zensupply.com/content/pdf/sargent/SARGENT_Full_Line_Catalog_compressed.pdf. Follow the parent closer's installation instructions when fitting the arm.
    14) Does the Sargent 25-SP10 come with a track like the Falcon 8230 arm?
    No. The Sargent 25-SP10 is a parallel security arm for Sargent 351, 281 and 1431 Series surface closers and uses a conventional parallel arm and shoe, not a track. The Falcon 8230-3077PLCM is a standard arm with track intended for 8230 Series automatic door operators. If the door has a track cut into the head and an operator rather than a manual closer, the 25-SP10 is not the replacement.
