Special plastic pulleys with aluminum frame. Assembled by galvanized steel nuts and screws so that you can easily dismantle the parts without any damage. Perfect for testing new ideas as well as standard pulley experiments.
This is a complete set of single, double and triple pulleys in tandem and parallel configuration.
Not recommended for young children due to the removable small screws and nuts that may get lost or present a choking hazard.
Single pulley and double parallel pulleys have 50-mm sheaves. Tandem pulleys use 50-mm, 40-mm and 30-mm sheaves.
