Replacement coarse (single speed) focus knob for GSO's Crayford focusers (only). Can replace the single speed knob on GSO's single and dual speed Crayford focusers. Will not work with GSO's Linear Bearing focusers or those from other brands. Item includes the knob and one locking set screw. Shaft diameter = 4.2mm; shaft depth = 26.5mm. Item weight = 1.1oz.
