This combination kit includes the parts to build either a Super Pulley with rod or Super Pulley with clamp.
The PASCO Super Pulley is the standard in physics labs. Its low-friction design produces excellent results. The precision spacing of the 10 spokes makes it ideal for photogate monitoring with PASCO’s computer interfaces and photogate systems.
The Super Pulley with its integral clamp makes setup and alignment easy. The pulley height is fully adjustable, so you can skim the top of a force table for parallax-free readings, yet keep the force parallel to the track on an inclined plane. Fits tables from 0 to 2.0 cm (13/16 in.) thick.
The rigid plastic pulley handle (14 cm long, 1.27 mm diameter) screws into a Super Pulley.
