Smooth, reliable pulley for force and tension experiments The Table Clamp Pulley is a durable, low-friction tool designed for teaching forces, simple machines, and mechanical advantage with confidence. Featuring a single pulley with deep V-grooves and rigid aluminum sheaves, this classroom-ready apparatus mounts securely to a table or bench using a convenient bottom-tightening clamp—making it ideal for hands-on investigations that stand up to repeated student use. Why Teachers Love the Table Clamp Pulley Low-friction performance: Smooth-turning aluminum sheaves produce reliable, repeatable results. Built for durability: Heavy aluminum frame and deep V-groove design withstand classroom wear and tear. Secure table mounting: Bottom-tightening “T”-screw clamp holds firmly during experiments. Easy classroom setup: Clamps to surfaces up to 1.25" thick for flexible use on lab benches and tables.
