UL Type 4 modular enclosures feature dust- and liquid-tight seals on sides, doors, and top and are for wet, non-corrosive industrial environments where equipment must be periodically hosed or washed down. The enclosures feature non-porous urethane gaskets that form a tight seal with carefully squared frame flanges. Also, silicone sealant is applied to all welded corner joints for added moisture protection. The modular frame design comes in 42 single- or double-bay sizes.
