APO Fiberglass (FRP) NEMA 4X Enclosures

Non-metallic Modular Fiberglass Electrical Enclosures

Applications

APO modular fiberglass electrical enclosures are designed for use as insulated electrical junction boxes, terminal wiring boxes, instrument housings and electrical control enclosures in highly corrosive environments.

Features

  • 9 available sizes from 7” x 6” to 24” x 24” (H x W).
  • Enclosures are maintenance free and corrosion resistant.
