Sachtler SP 75 Ground Spreader fits all 75mm bowl tripods and Pedestal C I and is used when shooting on a level surface such as a studio, city street, office, sport field, or stadium. It allows for rapid setup and pull-down by keeping tripod legs at an equal or preset distance relative to each other. The SP 75 spreader attaches directly to the bottom of a tripod’s feet and its telescopic arms allow for the extension of the legs.
