Surface Mounting NEMA 4 - NEMA 3R - NEMA 7 Cast Iron - Hot Dipped Galvanized
Standard Construction:
Box and cover of cast iron.
Two mounting lugs each long side on standard centers. Specify bolt size.
Available Extras:
Drilling and tapping.
Bosses for five threads to sketch.
Interior mounting buttons tapped blind.
Bronze hinges for heavy covers. Having a precision machined surface on flange of box and matching surface on cover, all H6000 Type boxes are NEMA 3R (Raintight) and NEMA IV (Weatherproof) without need for a gasket.
H6000 type explosion housings have been specified and installed in Class I, groups C and D hazardous locations by the larger engineering and erecting companies. Manufactured to the standards of the Underwriters’ Laboratories, Inc., but not tested by them. Competent specifying engineers have readily recognized the substantial construction of box and cover with the precision finished metal to metal joint as wholly adequate for the use of these boxes for pull and junction service and as enclosures for devices in gasoline refineries, chemical process and powder plants, gas pumping stations and other hazardous locations. Conduit entrances must have five threads. Check wall of box with table in the Ordering Information section.
