DDIN Standard Transmission Stringing Blocks are engineered for heavy-duty conductor handling in transmission and distribution projects. Built from high-strength aluminum alloy, these blocks are lightweight yet extremely durable for long-term field performance.

Each sheave is urethane-lined to protect conductors from surface damage, while precision anti-friction ball bearings packed with synthetic aviation grease ensure smooth operation even under extreme working conditions.

Available in multiple sheave sizes (12″, 16″, 22″, and 28″) to match various conductor diameters and job requirements — making them a reliable solution for professional line stringing operations.
