Single Sheave Pulley (Rigid Frame) Closed Type

These are closed type pulleys covered within the High-Tensile Steel plate instead of High-Tensile Steel sheet. For better security and swiveling, the shank of the hook joins together with pivot of the pulley by means of hot forging which makes hook and frame integrated. These pulleys are sturdier and more rigid against rough use; it also has more load bearing capacity to weight ratio.
