Insulating Rubber Blankets


Superior quality dielectric blankets are designed, manufactured, and tested in the USA in strict accordance to current ASTM D1048 specifications.

The Class Identification voltage rating system is the same as insulating rubber gloves but there is no colored identification tag.

Class 0 and Class 4 Blankets are both Type II:
made of ozone-resistant EPDM synthetic rubber.

Class 2, Type I Blanket is made of natural rubber.

All blankets measure 36” x 36” unless otherwise identified.

Care and Inspection of Rubber Blankets

As with other live line tools and safety products, proper care, inspection, and storage of Rubber Blankets is essential. Before each use, it is imperative to visually inspect your rubber blankets. When inspecting, be sure to look for rips, tears, holes, punctures, embedded wire, ozone cutting, and chemical deterioration. Should any of these be evident, remove the blanket from service. If additional information is needed, please review ASTM F1236, Standard Guide for visual inspection of electrical protective rubber products.
