Double Parallel Pulley – 50mm Low-Friction Aluminum Dual Wheel with Hooked Metal Frame by GSC International Inc.
This double parallel pulley from GSC International Inc. is designed for force and motion experiments, simple machine lessons, and physics lab demonstrations. Built with two parallel 50mm pulley wheels, it allows students to explore mechanical advantage, load distribution, and multi-line pulley systems with smooth, consistent performance.
Each wheel is made of low-friction aluminum and mounted in a durable metal housing for long-term classroom use. Hooks at both the top and bottom make setup fast and secure, while the accurately centered wheels help ensure stable operation during repeated experiments and demonstrations.
