CHANCE Class 4 Insulator Cover, 12″ Tall, Grip-All Adapter

These covers provide a highly versatile system of covering up a wide variety of configurations on distribution systems. The conductor covers couple with the insulator covers and dead-end units to cover pin-type or post-type insulator construction. Together, they virtually surround the hot parts and hardware to give lineworkers extra protection when rubber gloving or using hot sticks. Each item is fitted with an adapter for multiposition handling by Grip-All clampsticks. These covers also couple with Chance 25 kV covers, Classes 2, 3, and 4 of rubber line hose, and major brands of rubber insulator hoods.

All covers are bright orange in color. All are made of high-density polyethylene in a uniform wall thickness for excellent dielectric/puncture strength and perform well from -50˚ to 170˚F. Ultra-violet stabilizers in the material help inhibit degradation as a result of atmospheric exposure. Deadend cover fits three 10″-diameter porcelain bells or polymer dead-end insulators and couples with the line cover. To meet the Class 4 rating, the dead-end cover must be used in conjunction with a rubber insulating blanket covering the coupler to the line cover. Failure to use a blanket to cover the coupler may result in electrical shock, severe injury, or death by electrocution.
