Chance Class 4 flexible blankets help protect workers from accidental contact with energized components during line maintenance. Made of ozone/corona-resistant elastomer, these blankets offer excellent performance properties in accordance with ASTM Standard Specification D1048. The special formulation exhibits superior resistance to long-term aging/checking and will retain its high-visibility orange color. Versatile protection; maximum rating and flexible to cover many irregular shapes, rubber blankets typically are used with conductor covers (flexible or rigid) on deadends, apparatus, secondary racks, poletop pins and crossarms.
