Abstract
An improved bundle conductor stringing block having a main frame constructed essentially of structural steel components and including a cantilever suspension yoke positioned to form a tow-line receiving passage through which a helicopter can dispense a conductor tow-line onto a central one of multiple sheaves. Guide members pivoted to the opposite sides of the tow-line passage guide the tow-line onto the central sheave and include toggle spring device engageable by a running board at the trailing end of the tow-line to engage these members and pivot them in either direction to retracted positions along the block side frame.
