GMP 74135 Universal Stringing Block - Bethea Style, 2,500 lb WLL, Spring-Loaded Pin Latch

A lightweight, versatile, and dependable engineer's sheave. The GMP Bethea-style UB-1-A Universal Roller delivers the perfect balance of strength and portability for demanding stringing operations. At 11 lbs, it's easy to handle in the field, yet rugged enough to withstand tough conditions while supporting heavy conductor loads. Designed for compatibility, the UB-1-A can be intermixed with similar stringing blocks and mounting attachments from other manufacturers without affecting conductor sag or tension.

Built for long-term reliability, the UB-1-A uses aluminum parts cast from high-strength A356 alloy, heat-treated to the T6 condition. This ensures durability under rough treatment and adverse jobsite environments while maintaining performance under load. Permanently lubricated ball bearings and precision machining provide smooth, efficient operation across a wide temperature range.
