Hubbell offers a wide variety of configurations available in high-impact nylon and metal wall plates. In 1981, Hubbell was the first manufacturer to introduce nylon wall plates. Hubbell only offers plastic plates made of a high-impact material and does not offer wallplates made of materials that may be subject to breakage in abusive environments. Hubbell offers only the best grade of stainless steel type 302/304, which is 18% chromium, 8% nickel, and non-magnetic providing superior corrosion resistance versus type 430 stainless steel. When you specify Hubbell wallplates you can be assured of the highest quality materials providing extended life in the most abusive environments.
