Your cart is empty. One (1) high quality, triple plastic pulley in tandem, on an open sided steel frame, with hooks at each end carrying three ball bearing plastic pulleys with diameters of 25, 38 and 50 mm respectively. The open sided frame greatly facilitates stringing up as no 'threading' is involved.
Inner gap of pulley measures 3 mm, overall length is 17.6 cm. Capable of holding over 30 lbs of weight.

I ordered two sets...the inside roller is really smooth and that is very important in my science project. They are well made and the variable sizes are just what is needed for my experiments...value to cost ratio= very good.
