CATV Crossover Clamps are employed to clamp on duple messengers where they transverse at right angles so as to prevent wear as well as abrasion. The clamp sections are adequately wide and long. The diameter bolts are featured with oval shoulders so as to prevent turning after being tightened. These clamps can be used with strand diameter that ranges. Made of ductile iron as well as hot-dip galvanization, these insure proper fastening as well as accurate measurements. CATV Crossover Clamps have oval shoulders.
