74 series transmission blocks

MAXIMIZE STRINGING DISTANCE, MINIMIZE PULLING TENSION, REDUCE LOADS

The 74 Series single-conductor stringing blocks are an ideal choice for stringing large-diameter transmission-class conductor. These blocks are available with 10″, 12″, 14″, and 16″ (OD) sheaves, and they are light-weight, yet exceptionally rugged, reliable, and durable. Their low-friction bearings render high block efficiency, which helps to maximize stringing distances while minimizing pulling tensions and reducing loads on stringing equipment. Combined with the associated family of hardware and accessories, the 74 Series affords utilities and their contractors exceptional versatility in how and where it may be deployed and in the range of installation problems it can help solve.
