The Impact 40" Extension Grip Arm (Silver) is a staple of any film, video or photo production set. An ideal mate to an optional C-Stand, the 40" non-skid bar slips neatly into an optional grip head mounted to the stand allowing you to offset it and cantilever a flag, gobo, light or other accessory in front of it. The 40" bar has a permanently attached 2.5" grip head with a large ergonomic T-handle. The Grip Arm is often used as a short boom.
