An ideal solution for a variety of
mobile SR applications, the I-282H
includes a pole cup for pole
mounting with either 1 1/2" or 1
3/8" diameters. Or by using the
included yoke mount with swivel
extension feet, the I282-H can be
vertically or horizontally mounted
for pan and tilt focusing or used as
a floor monitor. For truss mounting,
the yoke accepts most industry
standard truss clamps.
