WIDE THROAT HELICOPTER STRINGING BLOCKS
Helicopter blocks are Ideal for stringing multiple sizes of single overhead conductors where the pilot line will be flown in. Some of the unique features include the exclusive “Snap Lock” fold away helicopter arm, which eliminates the need for removing pins to deploy or retract the fly arm. The strong aluminum alloy stringing block utilizes a “V-Groove” urethane lined sheave, designed to improve the installation of twisted pair conductors, commonly referred to as T2® or VR2®. A spring loaded side gate, 12,000 lb. working load combined with shielded bearings lubricated with a synthetic lubricant ensures smooth, consistent operation in the toughest of environments.
