The PTS Series of fiberglass boxes provide impact-resistance and durability with a blend of polycarbonate plastic and 10% glass fibers. This combination offers an extremely robust and long-lasting fiberglass-reinforced plastic box that can displace metal enclosures in some cases. The PTS series fiberglass box also delivers protection against harsh and wet environments and meets the specifications for NEMA 4X and 6 and IP67. Clear covers are available as an option, which allows inspection of the box contents without breaking the seal. Select a model of our PTS series fiberglass-reinforced plastic box.
