    Sargent 25OTB EN – Frequently Asked Questions

    1) Can I use the Sargent 25-OTB track arm on the push side of a door?
    No. The 25-OTB is a pull side track arm, meaning the closer body mounts on the hinge side face of the door (or the frame, depending on the application) and the track runs on the pull side of the opening. For a push side installation you need a parallel arm or top jamb configuration instead.
    2) I need a hold-open arm instead of a bumper track arm - what are my options?
    The Sargent 25-OTB provides an integrated bumper that cushions the door at the open position, but it is not a hold-open device. If the opening needs the door to stay open, hold-open arm assemblies include the LCN 1250-3049/PA, a non-handed hold open arm with a parallel arm shoe and adjustable hold open, the LCN 4010-3049 hold open arm with an adjustable elbow, and the Falcon SC70A-3049/PA hold open arm with PA bracket. Each mounts to its own closer series, so choose by the closer body on the door.
    3) What is the LCN equivalent of a Sargent 25-OTB track arm if the closer on the door is an LCN 4000T?
    The Sargent 25-OTB is a pull side track arm with an integrated bumper built for Sargent 351, 281 and 1431 Series closers, so it does not carry over to an LCN body. For an LCN 4000T Series closer the matching replacement is the LCN 4000T-3077T standard arm. Arm assemblies are keyed to the closer series they mount to, so match the arm to the closer body already on the door rather than to the mounting style alone.
    4) Will a Sargent 25-OTB work on a center hung floor pivot door?
    No. The Sargent 25-OTB is a pull side track arm for Sargent 351, 281 and 1431 Series surface closers. A center hung door running on a floor pivot with an overhead concealed closer takes a different assembly - the Falcon OHC100A-DP is a center hung floor pivot with end load arm for OHC100 Series closers. Confirm whether the opening uses a surface closer or an overhead concealed closer before selecting.
    5) Do I still need a separate wall stop if I install the 25-OTB arm?
    The 25-OTB has a bumper built into the track, which cushions the door at the open position and takes the impact off walls, frames, and nearby hardware. That is the point of the OTB version over a plain track arm. Whether you keep a dedicated wall or floor stop is a call for your opening, but the integrated bumper is doing the stopping work at the track.
    6) What finishes does the Sargent 25-OTB track arm come in?
    Five sprayed enamel finishes: EAB sprayed brass, EB sprayed bronze to match dark satin bronze, ED sprayed bronze to match dark statuary bronze, EN sprayed aluminum, and EP sprayed bronze to match satin bronze. Pick the one that matches the closer bodies already on your other openings so the run of doors reads the same.
    7) Is a track arm closer suitable for a high traffic school or hospital corridor?
    Yes. The Sargent 25-OTB is rated heavy duty and Grade 1, which is the top ANSI/BHMA durability tier for door hardware, and it is specified for commercial rather than residential use. That is the right spec for classroom, patient corridor, and lobby doors that cycle all day.
    8) Why choose a track arm over a standard swinging closer arm?
    A track arm keeps the hardware tight to the door and frame instead of projecting out into the opening, which is why the 25-OTB is described as low profile. Buyers pick it where appearance matters or where a projecting arm would be vulnerable, such as schools and healthcare. A conventional regular or parallel arm assembly, like the LCN 1260-3077 regular arm with parallel arm bracket, is the alternative when you want a standard swing arm rather than a track.
    9) The door needs a positive stop at the open position rather than a cushion - is the 25-OTB right?
    The Sargent 25-OTB bumper cushions the door as it opens to protect walls and adjacent hardware, which is a cushioned stop rather than a rigid one. Where a hard dead stop is wanted, the Falcon SC60A-3049DS is a hold-open dead stop parallel arm assembly for SC60A Series closers. That is a parallel arm mount, not a pull side track, so confirm the closer series and mounting face before ordering.
    10) Which of these arms are track arms and which are swing arms?
    The Sargent 25-OTB is a pull side track arm, meaning the arm rides in a track mounted on the door or frame rather than folding at an elbow. Among other arm assemblies, the Falcon 8230-3077PLCM is a standard arm with track for 8230 Series automatic operators. The LCN 1260-3077 regular arm with parallel arm bracket, the LCN 4000T-3077T standard arm, and the LCN 4010-3049 hold open arm with adjustable elbow are conventional swing arm assemblies. Track and swing arms are not interchangeable on the same closer prep.
    11) Is a parallel arm assembly a substitute for the 25-OTB on a pull side install?
    No. The Sargent 25-OTB is built specifically for pull side mounting on Sargent 351, 281 and 1431 Series closers. Parallel arm assemblies such as the LCN 1250-3049/PA with parallel arm shoe, the LCN 1260-3077 with parallel arm bracket, and the Falcon SC60A-3049DS parallel arm assembly mount the closer on the push side of the door with the arm folded flat against the frame face. The two mounting methods use different frame preps and soffit brackets, so one does not drop in for the other.
    12) We are standardizing arms across a school - does the Sargent 25-OTB let us use one part on every door?
    The Sargent 25-OTB is a Grade 1, heavy duty commercial component and it covers Sargent 351, 281 and 1431 Series closers, so one part number handles pull side track openings across all three of those closer families. It does not cover doors running other closer brands - those need their own series arms, such as the LCN 1250-3049/PA for 1250 Series, the LCN 1260-3077 for 1260 Series, or the Falcon SC70A-3049/PA for SC70A Series. Standardizing on Sargent closers is what makes a single arm part number possible across the building.
    13) Can I use the 25-OTB on an automatic door operator?
    The Sargent 25-OTB is intended for Sargent 351, 281 and 1431 Series door closers, which are manual surface closers. An automatic operator uses its own arm assembly - for example the Falcon 8230-3077PLCM standard arm with track is built for 8230 Series automatic door operators. Match the arm to the operator or closer model on the header.
    14) My closer needs to mount on the frame head instead of the door. Is there a Sargent part for that?
    For a top jamb mount on a 351 closer, the Sargent 351A top jamb mounting plate is the related part. The 25-OTB itself is the pull side track arm assembly, so if the application calls for jamb mounting you will want the mounting plate alongside it rather than assuming the arm covers that condition.
    15) Does the 25-OTB track arm make the opening ADA compliant on its own?
    No single arm does that. The 25-OTB supports accessibility requirements when it is paired with an appropriate door closer, but the opening force and closing speed that determine ADA compliance are set by the closer itself and its adjustment, not by the arm. Spec the closer for the required opening force and use the arm to suit the mounting condition.
    16) Is the Sargent 25-OTB a genuine Sargent part or an aftermarket copy?
    It is the OEM Sargent component, which is why it seats correctly on 351, 281, and 1431 closer bodies without shimming or drilling. For a maintenance department standardizing on Sargent closers across a building, that means the replacement arm matches what is already mounted on the rest of the doors.
