The running out blocks are used for supporting overhead transmission line in stringing operation. The sheaves are made of high strength nylon or aluminum alloy. The sheaves are mounted on ball bearings. The frame is made of galvanized steel.

We have designed and manufactured running out blocks for single conductor, two bundled conductors, four bundled conductors and six bundled conductors stringing. The sheave size is changed from 120mm up to 1040mm diameter.
