Designed for attaching Marshall miniature and compact cameras to trusses, railings, and poles, this Marshall Electronics Pole Clamp features a 3" maximum jaw width and a ball mount for attaching the camera. The ball mount, which is removable, provides a 1/4"-20 camera screw and is swivel-adjustable for positioning the camera at desired angles. At full length the Pole Clamp measures 4.5", so it keeps your camera close to the pole while providing enough room to freely swivel-adjust it.
