Quadruple Parallel Pulleys (Pack of 10) – Four 50mm Low-Friction Aluminum Wheels with Hooked Metal Frame by GSC International Inc.
The Quadruple Parallel Pulley Pack from GSC International Inc. is designed for classrooms and labs that need multiple durable pulleys for force and motion activities. Each pulley features four 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 experiments.
Built with low-friction aluminum wheels and a powder-coated metal frame, these pulleys provide smooth motion, reliable alignment, and long-term durability for repeated student use. Hooks at both the top and bottom allow quick attachment to lab stands, support frames, or suspended loads for fast setup during demonstrations and hands-on learning.
