The 927 miter gear is used when the operating shaft must be carried down at a right angle to the damper shaft. Often the 927 miter gear is used with a model 301 or 315 ceiling regulator and a 3/8” square rod to control a damper above a ceiling. Damper shaft can be either 3/8” square or ½” round. Four ¼-20 mounting bolts and nuts are supplied with each set of miter gears. Contact the factory to accommodate shafts in other sizes.
Two models are available:
927C die cast gears — for regular applications
927B precision cut steel gears — for longer life and a variety of heavy-duty applications.
