Acratech Riser / Spacer

Spaces your tripod head above your tripod for additional clearance. The Riser has a 60mm (2 3/8" ) diameter by 25mm (1") height. It has a 3/8 -16 threaded hole in the bottom and a 3/8 -16 stud on the top. Also included is a 1/4 -20 bushing for the bottom. Ideal for use with heads that have a low panning lock knob (e.g many Manfrotto heads with the "arm" type knob) which can be difficult to operate when used on tripods like the Gitzo Systematics.
