The AS100 is a gray (ANSI 61) steel hole seal from HOL-SEALERS™. It features a polyester powder-coated finish over a galvanized front surface, providing durability and corrosion resistance. Designed specifically for 1-inch conduit holes, this seal effectively protects against dust, dirt, oil, and water. It is suitable for use on enclosure walls up to 0.31 inches thick. The seal includes an oil-resistant gasket, a 16-gauge galvanized steel backplate, and a plated stud (10-32 x 5/8 inches) with a wing nut, making it ideal for industrial applications.
