    A piece of lighting hardware from the "iron" category, most often used when hanging a conventional lighting fixture from a vertical boom. In its most basic form, consists of three parts:
    a lighting C-Clamp with the spud removed,
    a 12"-18" long, 1/2" I.D. pipe. (24" long if DTSA)
    and a sliding Tee fitting (or two if DTSA).

    A couple of abbrev.s:
    STSA=Single Tee Side Arm
    DTSA=Double Tee Side Arm

    City Theatrical has a line deemed Safer Sidearms.

    The Light Source has two alternatives:


    Any 90° pipe connector (Rota-Lock, Kee Klamp, fixed Cheeseborough, etc.) and a short length of pipe (12-36") may be used to create a sidearm.

    Noun or verb.

    See also pipe stiffener.
