4728-ALU Stringing Blocks

Constructed of an all aluminum alloy, these blocks are lightweight yet strong and durable. Their large throat openings allow for passage of most sleeves and connectors. The 79mm (3 1/8”) urethane lined sheaves prevent damage to the conductor and run smoothly on metal shielded bearings with a graphite lubricant.
