Triple Parallel Pulley – Three 50mm Low-Friction Aluminum Wheels with Hooked Metal Frame by GSC International Inc.

The Triple Parallel Pulley from GSC International Inc. is a durable, classroom-ready pulley designed for hands-on force and motion experiments. This pulley features three 50mm aluminum wheels mounted in a parallel configuration inside a strong metal housing, making it ideal for multi-line pulley systems, mechanical advantage demonstrations, and advanced physics lab setups.

Built with low-friction aluminum pulleys and a powder-coated metal frame, it provides smooth performance and long-term reliability for repeated student use. Hooks at both the top and bottom allow fast attachment to lab stands, support frames, and suspended loads, helping teachers and students set up experiments quickly and securely.
