This tandem pulley system will work great for any physics experiments. Its steel frame makes it very strong and capable of lifting heavy loads with ease. Mounting hooks are conveniently placed on both ends of the pulley which allows you, the operator, to use them in virtually in any situation. Having two separate wheels stacked on top of each other allows for advanced applications.
Pulley is constructed of hard plastic and metal.
NOTE: Pulley is intended for small school projects only, and can hold about 1kg in weight. Not intended for industrial use.
Dimension: Large wheel 2 inches (5.1cm) in diameter, 1/4 inch (6 mm) groove
