This solid iron double-hooked weight has a mass of 1000 grams (2.2 lbs). The hook is free to move and provides attachment points on both sides for connecting additional weights. The weight is painted black with a yellow weight identifier. The cylindrical weight measures 50mm (1.96 inches) in diameter and 67mm (2.64 inches) tall. A bored hole through the weight allows the moving double hook to sit flat when needed. Suitable for physics experiments involving force, mass, and equilibrium.
