    Sargent 25PHTB EN – Frequently Asked Questions

    1) Which Sargent door closers does the 25-PHTB hold-open track arm fit?
    The 25-PHTB is built for Sargent 351, 281 and 1431 Series closers. It is an OEM arm for those bodies, so it is not a universal replacement for other brands or other Sargent series. If the closer body on the door is a different series, this arm is the wrong part.
    2) Does this arm mount on the push side or the pull side of the door?
    Push side only. The 25-PHTB is a push side track application, so the closer body sits on the side the door opens away from you. On a pull side installation you need a regular or top jamb arm instead, not this track arm.
    3) Can I set the door to stay open at a specific angle with this arm?
    Yes, hold-open is part of the arm's function and it holds at selected angles, which is how you keep a corridor or classroom door propped without a kickdown. Keep in mind that a hold-open arm should not go on a fire rated opening unless the closer is a fire door application type with automatic release.
    4) Is there a hold-open closer arm that works with LCN closers instead of Sargent 351, 281 and 1431 closers?
    The Sargent 25-PHTB hold-open arm is built for Sargent 351, 281 and 1431 Series closers, so it should not be fitted to an LCN body. For LCN closers, the LCN 1250-3049/PA is a hold open arm assembly with a parallel arm shoe in a non-handed design with adjustable hold open for the 1250 Series, and the LCN 4010-3049 is a hold open arm with an adjustable elbow function for the 4020 Series. Match the arm to the closer series stamped on the body.
    5) I need a hold-open arm for a Falcon closer, not a Sargent. What are my options?
    The Sargent 25-PHTB is a push side track hold-open arm for Sargent 351, 281 and 1431 Series closers. On the Falcon side, the SC70A-3049/PA is a hold open arm with a PA bracket for SC70A Series closers, and the SC60A-3049DS is a hold-open dead stop parallel arm assembly for the SC60A Series. The dead stop version stops the door at the arm rather than relying on a bumper at the track, which is how the Sargent 25-PHTB cushions the swing.
    6) My door is on a center hung floor pivot. Will the Sargent 25-PHTB arm work?
    The Sargent 25-PHTB is a push side track arm for Sargent 351, 281 and 1431 Series surface door closers and is not intended for floor pivot applications. For a center hung floor pivot opening, the Falcon OHC100A-DP is a center hung floor pivot with end load arm for OHC100A Series overhead concealed closers. Confirm which closer type the opening actually has before ordering either part.
    7) Do I need a separate wall stop if I use this arm?
    The 25-PHTB has a bumper built into the track, which cushions the swing and takes the impact off the wall, frame and hardware at the open position. Many installs still add a floor or wall stop where the opening demands a hard stop, but the integrated bumper is doing the cushioning here.
    8) Is this arm rated for high traffic commercial openings like schools and hospitals?
    It is a Grade 1, heavy duty commercial part, which is the level specified for schools, hospitals, offices and other high-cycle openings. Grade 1 is the top ANSI/BHMA duty tier, so it is the right choice for standardizing across a facility rather than a light residential door.
    9) What finishes can I get the Sargent 25-PHTB arm in?
    Five sprayed enamel finishes: EAB sprayed brass, EN sprayed aluminum, EP bronze enamel matched to satin bronze, EB bronze enamel matched to dark satin bronze, and ED bronze enamel matched to dark statuary bronze. Pick the one already on the closer bodies in the building so the replacement arm does not stand out on one door.
    10) What is the difference between a hold-open track arm with a bumper and a hold-open dead stop arm?
    A track arm like the 25-PHTB rides in a low-profile track on the push side and uses a built-in bumper to cushion the door at the open position. A dead stop arm, such as the Falcon SC60A-3049DS hold-open dead stop parallel arm, stops the door hard through the arm itself. Choose the bumper track where you want a cushioned stop and a cleaner, lower profile; choose dead stop where the door must be positively stopped by the arm.
    11) What is the difference between a track arm like the Sargent 25-PHTB and a parallel arm hold-open assembly?
    The Sargent 25-PHTB is a push side track arm: the arm rides in a low-profile track on the door or frame and holds the door open at selected angles, with an integrated bumper cushioning the swing. A parallel arm hold-open assembly such as the Falcon SC70A-3049/PA uses a PA bracket and a jointed arm that folds back along the face of the door, and the LCN 1250-3049/PA uses a parallel arm shoe with adjustable hold open. Track and parallel arm hardware are not interchangeable on the same closer body, so specify by the mounting the closer was set up for.
    12) If I do not need hold-open, is there a plain arm I can use instead?
    The Sargent 25-PHTB is specifically a hold-open arm with an integrated bumper. If the opening does not need to stand open, standard non-hold-open arms include the LCN 4000T-3077T standard arm replacement component for the 4000T Series, the LCN 1260-3077 regular arm with parallel arm bracket for the 1260 Series, and the Falcon 8230-3077PLCM standard arm with track for 8230 Series automatic door operators. Each of those is tied to its own closer series, so it is not a drop-in for a Sargent 351, 281 or 1431.
    13) Can I use the Falcon 8230-3077PLCM track arm in place of the Sargent 25-PHTB since both use a track?
    No. The Falcon 8230-3077PLCM is a standard arm with track for 8230 Series automatic door operators, which is a powered operator rather than a manual surface closer, and it is a standard arm with no hold-open or bumper. The Sargent 25-PHTB is a push side track hold-open arm with an integrated bumper for Sargent 351, 281 and 1431 Series door closers. Sharing a track format does not make them interchangeable.
    14) If I am top jamb mounting a Sargent 351 closer, is there a plate I should order with it?
    Sargent offers the 351A top jamb mounting plate for that application, and it is the companion piece when the frame face does not give you enough solid backing for the closer shoe. The 25-PHTB arm itself is the push side track assembly; the mounting plate is a separate order.
    15) For a high traffic commercial opening, how does the Sargent 25-PHTB compare with other hold-open arms on duty rating?
    The Sargent 25-PHTB is a heavy duty, Grade 1 commercial closer arm, built for schools, hospitals, offices and other high-traffic environments, with an integrated bumper to absorb the swing. Alternative hold-open arms such as the Falcon SC60A-3049DS hold-open dead stop parallel arm assembly and the LCN 4010-3049 hold open arm with adjustable elbow function are each matched to their own closer series, so the closer already on the door drives the choice more than the arm itself.
