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

The Triple Tandem Pulley from GSC International Inc. is a durable, classroom-ready tool designed for hands-on force and motion investigations. This advanced pulley features three aluminum wheels stacked in tandem inside a strong metal housing, making it ideal for demonstrating mechanical advantage, pulley ratios, and multi-line systems in physics and STEM labs.

Built with low-friction aluminum wheels, this pulley delivers smooth, consistent motion during experiments and demonstrations. The metal frame includes hooks at both the top and bottom, allowing fast mounting to lab stands, support frames, or suspended loads. Deep grooves in each wheel help keep cords aligned and secure during repeated classroom use.
