HD6000 type heavy duty boxes are heavy walled assemblies substantially gasketed on wide flanges for the most severe types of weathertight and watertight installations.
They are ideal for submersion service and have been successfully installed in flooded manholes, on docks, piers, seawalls, underground and in sub-stations, and will remain watertight under high heads of water.
Protected steel cap screws are standard but monel, bronze or stainless can be supplied. Conduit entrance should be ordered with bosses for five.-threads to insure watertight conduit entry if the wall thickness is less than that required for five threads. Interior mounting buttons located on specified centers and tapped blind for watertightness provide an excellent method for mounting panels, relays, transformers and similar devices.

HD6000 type boxes are acceptable for Class II, Groups E, F, and G hazardous locations when ordered with

1. Vellumoid gasket – change “Add 8% to list price of box” to “At additional cost”.
2. Bossed conduit entrances tapped for five threads.

H8000 type boxes feature wide flanges that provide ample contact with cover and gasket to insure tightness even under widely varying temperature and climatic changes. Flange widths are graduated from a minimum of three quarters of an inch on small boxes to a width of one and a half inches on large boxes. Screws are properly spaced to make these boxes weathertight under severe natural forces of driving rain, snow, sleet or drippage.
Conduit entrances of five tapped threads for raintight requirements usually require bosses.
Mounting lugs afford easier installation and add sturdiness to the conduit system.
For Class II, Groups E, F and G hazardous locations,

H8000 Type Boxes for class II, (Groups E, F, and G) Hazardous locations

Class II, Groups E, F and G hazardous locations are ones in which explosive mixtures of air with metal dust (Group E), or carbon, coke or coal dust (Group F), or grain dust (Group G), are encountered. Enclosures with adequate flanges, mechanically held gaskets of proper composition, and bossed and tapped conduit entrances with five threads will meet Class II requirements.
All H8000 type boxes listed above will conform to these requirements when ordered specifically as follows:

1. With gasket of vellumoid: Specify "Mechanically Attached" (Extra 10%)
2. With bossed and tapped conduit entrances of five threads Mounting Lugs
3. Mounting lugs are optional, but mounting holes through box are not permissible.
   See further listing on Class II boxes, under Metal Pipe and Pole Bases and under Explosion Housing.

H5400 and H5600 type and H6000 type boxes for Class I, Groups C and D hazardous location are listed under Explosion Housing.
