Product Overview
The WH-18 medium hinged enclosure is available in gray flame-retardant ABS plastic for indoor use, or gray polycarbonate for outdoor use (with the option of a clear cover when selecting outdoor use). The foam gasket in the cover makes the enclosure ideal for use in a wide range of adverse conditions, while the padlock hasp provides an additional layer of protection against unwanted tampering. Mounting your device comes easily with the use of the included stainless steel wall-mounting hardware or, the sold separately pole mounting kit. Secure your PCB utilizing the 8 mounting bosses located in the base, or take advantage of the mounting panel or DIN rail kit (sold separately). Note: The indoor configuration (ABS version) has not undergone formal NEMA testing, NEMA ratings for this enclosure are based on UL tests conducted on the outdoor configuration (polycarbonate version).
