A reliable fulcrum is essential for successful meter stick lever demonstrations—and this cast aluminum balance support delivers. Built to last, it won’t flex or warp during use. Its 3" × 3" wide base provides stability, while the 7.5" tall arch allows easy access for student hands. The smooth, notched top is perfectly shaped to hold a knife-edge clamp securely (sold separately: AP4672), ensuring smooth and accurate balance operations. Ideal for physics and physical science classes. Meter stick and clamp not included
