Grounded Stringing Blocks, 28″

DDIN Grounded Stringing Blocks are assembled with a unique grounding attachment mounted directly to the axle. The 4-½” x ¾” ground stud can accept virtually any ground clamp, while the dual heavy-duty springs keep the roller in constant contact with the conductor. These blocks maintain the same trusted features as DDIN’s Standard Blocks including urethane-lined sheaves, anti-friction shielded ball bearings packed with aviation grease, and a high-strength aluminum alloy frame.
