Bundle conductor stringing block gate

摘要

An improved line stringing block utilizes a double gate mechanism to transfer a lead line from the exterior of the block frame to the interior of the block frame. An outer gate is held open until the line is received within a passageway in the block frame. A non-load bearing inner gate is held closed to maintain alignment of said frame until the line is received in the passageway. A spring loaded trigger within the passageway releases the inner gate and closes the outer gate which becomes a load bearing gate.
