Product OverviewThe SK-29 knockout enclosure is molded from fiberglass reinforced gray polycarbonate and comes standard with a polyurethane gasket, and PCB mounting bosses in the base. Designed for versatility, captive plastic machine screws are utilized to assemble the enclosure for easy cover on/off convenience, while the 16 x M20; 2 x M20/25; 2 x M32/40 metric knockouts can be easily removed with the use of a flathead screw driver or similar tool to create cable pass-throughs in the field. The all-plastic enclosure provides the option of a tinted clear cover for quick monitoring of internal components, or a gray cover for applications where privacy and consistency is important.
