A lightweight, versatile, and dependable engineer’s sheave. The Bethea UB-1-A Universal Roller delivers the perfect balance of strength and portability for demanding stringing operations. At just 9.4 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.
