Cable feeding sheaves slide into the end of conduit in a manhole wall, allowing the cable being fed into the conduit to roll smoothly over the sheave from all angles. The frame is made from steel for durability while the sheave is made from aluminum alloy with self-lubricating bearings. The sheaves have a split tube for easy removal after cable is installed. Note: cable feeding sheaves are not designed for use with fiber optic cable due to bending radius limitations.
