    Sargent 25PSH EB – Frequently Asked Questions

    1) Do I have to order a finish for the Sargent 25-PSH arm, and what are the choices?
    Yes, finish is the one thing you specify. Five sprayed enamel finishes are offered: EAB sprayed brass enamel, EN sprayed aluminum enamel, EP sprayed bronze enamel matched to satin bronze, EB sprayed bronze enamel matched to dark satin bronze, and ED sprayed bronze enamel matched to dark statuary bronze. If you are replacing one arm on a run of doors, match the code already on the closer body so the arm does not stand out against the rest of the openings.
    2) Can I use this parallel arm if my closer is mounted on the frame face above the door?
    No. Top jamb mounting puts the closer on the frame face and needs a mounting plate, not a parallel arm. For Sargent 351 closers going on top jamb, the 351A top jamb mounting plate is the part for that job. The 25-PSH is strictly a parallel arm assembly for push side closer mounting.
    3) Is the LCN 1250-3049/PA a substitute for the Sargent 25-PSH heavy duty positive stop hold-open arm?
    They do the same job on different closers. The LCN 1250-3049/PA is a hold open arm assembly with a parallel arm shoe for LCN 1250 Series closers, with a non-handed design and adjustable hold open. The Sargent 25-PSH is a heavy duty parallel arm for Sargent 351, 281 and 1431 Series closers and adds a positive stop that prevents the door from swinging past the set angle, protecting the wall and frame. If the closer body is LCN, use the LCN arm; if it is Sargent, use the 25-PSH.
    4) What is the closest equivalent to the Sargent 25-PSH parallel arm if the closer on the door is a Falcon instead of a Sargent?
    For a Falcon closer, stay within the Falcon arm family rather than fitting the Sargent 25-PSH, which is built as an OEM replacement for Sargent 351, 281 and 1431 Series closers. The Falcon SC60A-3049DS is a hold-open dead stop parallel arm assembly, which is the functional counterpart - hold-open combined with a stop that limits swing - for SC60A Series closers. For an SC70A Series closer, the Falcon SC70A-3049/PA is a hold open arm supplied with the PA bracket for parallel mounting. Arms are matched to the closer body and spindle they mount on, so the series has to match the closer already on the door.
    5) Will a standard arm like the LCN 4000T-3077T work in place of the Sargent 25-PSH?
    No - those are different arm types as well as different closer series. The LCN 4000T-3077T is a standard arm replacement component for LCN 4000T Series closers, and the LCN 1260-3077 is a regular arm with parallel arm bracket for 1260 Series closers; neither carries a hold-open or a positive stop. The Sargent 25-PSH is a heavy duty parallel arm for Sargent 351, 281 and 1431 Series closers that both holds the door open at a set angle and stops it from swinging past that angle. If the opening needs the door to stay open or needs the swing limited, a standard arm will not deliver it.
    6) What is the difference between a positive stop hold-open arm and a plain hold-open arm?
    Two jobs in one arm. The positive stop stops the door dead at a set angle so the leaf cannot swing past it and punch a lever or a closer body into the wall behind it. The hold-open holds the door standing open at that angle until someone pushes it closed. A plain hold-open arm will park the door but gives you no mechanical stop, so you still need a wall or floor stop to protect the opening. On the Sargent 25-PSH you get both in the one assembly.
    7) Is the Sargent 25-PSH arm heavy enough for a school or hospital corridor door?
    It is rated Heavy Duty and Grade 1, which is the top ANSI/BHMA durability tier for commercial door hardware and the level normally specified for high-traffic institutional openings. Sargent lists it for commercial use in schools, healthcare facilities, offices and retail. For a property manager standardizing corridor doors across a building, that is the grade you want on the busiest leaves.
    8) Does a hold-open arm like this help with ADA accessibility?
    The hold-open function supports accessibility compliance when it is used with a compatible door closer, because the leaf can be parked open for wheelchair, gurney or cart traffic instead of being fought against closer spring force on every pass. The arm alone does not make an opening ADA compliant; opening force and closing speed are set at the closer, not the arm. One caution: on a fire rated opening a mechanical hold-open arm is not permitted, since the door has to be free to self close and latch.
    9) I do not need the stop function, just hold-open. What arm should I look at instead of a positive stop arm?
    Where the wall or an adjacent object does not need protecting, a plain hold open arm without the positive stop is the simpler choice. The LCN 4010-3049 is a hold open arm for door closers with an adjustable elbow function, and the LCN 1250-3049/PA is a hold open arm assembly with a parallel arm shoe and adjustable hold open. The Sargent 25-PSH combines both functions - hold-open plus a positive stop that limits how far the door can swing - so it is the choice when the opening needs the swing mechanically limited as well.
    10) For a school corridor where the doors get pushed hard into the wall, which arm should I standardize on across brands?
    Specify an arm that includes a mechanical stop, not hold-open alone. On Sargent 351, 281 and 1431 Series closers, the 25-PSH is the heavy duty parallel arm that adds a positive stop to keep the door from opening past the set angle along with the hold-open function, and it is a Grade 1 commercial part. On Falcon SC60A Series closers, the SC60A-3049DS is the hold-open dead stop parallel arm assembly that pairs the same two functions. Keeping the stop function consistent across both closer brands gives the same wall protection on every opening.
    11) Is the Sargent 25-PSH a genuine OEM part or an aftermarket copy?
    It is a Sargent OEM replacement arm, matched to the 351, 281 and 1431 Series closers, so the shoe, forearm and pinion connection land where the factory arm did. For institutional buyers running a standardized closer package, that matters: an aftermarket arm can bolt on and still change hold-open angle or stop geometry.
    12) Will this arm hold up outdoors or in a wet entry vestibule?
    The sprayed enamel finish on the Sargent 25-PSH resists wear, corrosion and impact damage, and the arm is built from high-strength commercial-grade material for demanding environments. Enamel finishes are field touch-up friendly, which is useful on an exterior entry where the arm takes weather and cart strikes.
