    Sargent 25PH9 EN – Frequently Asked Questions

    1) Which Sargent door closers does the 25-PH9 parallel arm fit?
    The 25-PH9 friction hold-open arm is an OEM replacement for Sargent 351, 281 and 1431 Series closers. It is built for those bodies specifically, so it is not a universal arm. If your closer body is a different Sargent series or another brand, this is the wrong arm.
    2) What does friction hold-open mean on a door closer arm, and is it the same as a dead stop?
    Friction hold-open holds the door at whatever angle you swing it to, using friction in the arm rather than a mechanical stop. Release the door and the closer controls it shut normally. It does not stop the door at a fixed degree the way a dead stop arm does. If you need the arm to physically limit the swing and protect the closer, look at a hold-open dead stop assembly such as the Falcon SC60A-3049DS instead.
    3) Can I use a friction hold-open arm on a fire rated door?
    No. Fire doors have to self close and latch, so a hold-open arm that keeps the leaf open is not appropriate on a labeled opening. Use a non hold-open arm on those doors, and reserve the 25-PH9 friction hold-open for non-rated openings where you want the door parked open.
    4) My closer is an LCN or Falcon, not a Sargent. What hold-open arm do I order?
    Arms are series specific, so cross-brand swaps do not work. For an LCN 1250 closer the 1250-3049/PA hold open arm with parallel arm shoe is the matching non-handed assembly, and LCN's 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 serves SC70A closers. Match the arm to the closer body you actually have.
    5) What is the LCN equivalent of the Sargent 25-PH9 friction hold-open parallel arm?
    The closest LCN counterpart is the LCN 1250-3049/PA, a hold open arm assembly with a parallel arm shoe built on a non-handed design with adjustable hold open. The Sargent 25-PH9 is a friction hold-open standard parallel arm made as an OEM replacement for Sargent 351, 281, and 1431 Series closers, so the LCN part is the right choice only when the closer body itself is an LCN 1250 Series. Arms are matched to the closer they mount on, not to each other.
    6) If the door needs a hold-open arm that also stops the door at a set point, what should I use instead of the Sargent 25-PH9?
    Look at the Falcon SC60A-3049DS, a hold-open dead stop parallel arm assembly. The dead stop feature arrests the door swing at a fixed point, which the Sargent 25-PH9 does not do - the 25-PH9 is a friction hold-open that holds the door at a chosen position and otherwise allows normal controlled swing. The SC60A arm mounts to Falcon SC60A Series closers, so it is a substitute only when you are also changing or already running that closer.
    7) Is a parallel arm the right choice, or should I use a regular arm?
    Parallel mount puts the arm back against the face of the door under the frame stop, which keeps it out of the opening and is the usual pick for corridors, stairwells and anywhere the arm could be grabbed or abused. A regular arm mounts on the pull side with the arm projecting into the opening and gives more mechanical advantage. The 25-PH9 is a standard parallel arm, so it only suits parallel installations on 351, 281 or 1431 closers.
    8) Is this Sargent hold-open arm rated for heavy commercial traffic?
    It is a commercial component graded Grade 1 at a standard duty level, which covers schools, hospitals, offices and retail openings. For residential-only work it is more hardware than the opening needs.
    9) What finishes does the Sargent 25-PH9 arm come in, and can I match the closers already on my other doors?
    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 same code your existing Sargent closer covers carry and the replacement arm will read as original on the opening.
    10) Do I need a mounting plate or bracket with this parallel arm?
    Parallel mounting normally needs the appropriate shoe or bracket at the frame, and on top jamb work Sargent's 351A top jamb mounting plate is the companion piece sold alongside this arm. Check what is already on the frame: if the existing shoe and soffit prep are intact and in the same finish, the arm alone finishes the repair.
    11) Is a standard arm like the LCN 4000T-3077T a substitute for the Sargent 25-PH9?
    No. The LCN 4000T-3077T is a standard arm replacement component for the 4000T Series - a standard arm closes the door every time and offers no hold-open. The Sargent 25-PH9 is a friction hold-open parallel arm that holds the door open at a chosen angle for accessibility and loading applications. If the opening was specified with hold-open, a standard arm changes how the door behaves, and it is built for an LCN closer body rather than the Sargent 351, 281, or 1431 Series.
    12) We run Falcon SC70A closers on some doors and Sargent closers on others - can one hold-open arm cover both?
    No, you need two part numbers. The Falcon SC70A-3049/PA is a hold open arm with PA bracket for SC70A Series closers, while the Sargent 25-PH9 friction hold-open parallel arm is an OEM fit for Sargent 351, 281, and 1431 Series closers. Both deliver parallel-arm hold-open behavior, so the doors will operate alike, but the arm has to match the closer body it bolts to. For a facility standardizing on one arm, standardize the closer series first.
    13) What arm do I use for a center hung door on a floor pivot instead of the Sargent 25-PH9?
    A surface parallel arm will not serve a center hung pivot opening. The Falcon OHC100A-DP is a center hung floor pivot with end load arm for OHC100 Series door closers and is built for that condition. The Sargent 25-PH9 is a surface-applied friction hold-open parallel arm for Sargent 351, 281, and 1431 Series closers mounted on the door face. Confirm the pivot arrangement at the opening before ordering either one.
    14) Is the LCN 1260-3077 the same thing as the Sargent 25-PH9?
    They are different arm types. The LCN 1260-3077 is a regular arm with parallel arm bracket for 1260 Series closers, which is a regular arm configuration converted for parallel mounting and does not carry a hold-open feature. The Sargent 25-PH9 is a friction hold-open standard parallel arm, so it adds the ability to hold the leaf open at a selected angle. The LCN part also pairs to an LCN closer body rather than the Sargent 351, 281, or 1431 Series.
    15) Can I put the Sargent 25-PH9 on an automatic door operator?
    No. Arms for automatic operators are separate parts - the Falcon 8230-3077PLCM, for example, is a standard arm with track made for 8230 Series automatic door operators. The Sargent 25-PH9 is a friction hold-open parallel arm for the manual Sargent 351, 281, and 1431 Series surface closers. If the opening is powered, order the arm that matches the operator series.
    16) Does adding this arm make my door ADA compliant?
    On its own, no. Hold-open helps accessibility by letting the door stand open, but opening force and closing speed are set by the closer body. The 25-PH9 supports accessibility compliance when it is paired with a compatible Sargent 351, 281 or 1431 closer that is adjusted correctly.
    17) Which hold-open arm has an adjustable elbow rather than friction hold?
    The LCN 4010-3049 is a hold open arm for door closers with an adjustable elbow function, built on the 4020 Series. The Sargent 25-PH9 instead uses a friction hold-open, where resistance in the arm holds the door at the position you swing it to. Both give a held-open leaf; the adjustment method and the closer body they fit differ, since the 25-PH9 is an OEM arm for Sargent 351, 281, and 1431 Series closers.
