Enclosure Leg Kits
Electrical enclosures are designed to house industrial components and to protect them from the surrounding environment. They are also designed to protect operators from electric shock. They come in many different shapes, sizes and materials. Some things to consider when selecting the proper enclosure would be the number of components housed inside and what material and rating will provide the appropriate protection. Enclosures come in wall-mount, floor-mount (with legs) and freestanding (enclosure extends to the floor). When selecting freestanding enclosures, there are several enclosure bases to consider: floor stands, leg and casters and pedestals.
Hoffman Sanitary Leg Kits provide space between the floor and the enclosure for better wash down accessibility. They are available with fixed or independently adjustable legs. NEMA Type 4X rating is maintained when properly installed on a Hoffman Type 4X enclosure.

Hoffman Frame Feet are installed on the bottom of PROLINE frames to raise the frame 9 mm.
Hoffman Stainless Steel Legs mount to the bottom of a solid base to elevate the enclosure 4 inches from the floor. The legs are made of Type 304 stainless steel and are appropriate for hose-down applications.
Maintaining NEMA 4 Rating When Making Enclosure Penetrations
Cutouts are very common when modifying enclosures for push buttons, indication lights, conduit entries or mounting hardware. Cutting into an enclosure runs the risk of eliminating the protective nature of the NEMA rated attributes. Proper steps must be followed in order to preserve the NEMA rating of an enclosure.
Devices mounted to the enclosure must have the same NEMA rating as the enclosure. This means that if the devices are installed to the manufacturer's specifications, they will be able to maintain the NEMA rating of the enclosure.
Water tight conduit hubs must be used when running wire through a cutout in an enclosure. There are many different types of conduit hubs that are used to secure conduit to an enclosure. However, only certain conduit hubs are rated for a watertight seal. By using water tight hubs, the NEMA rating of the enclosure is maintained.
Bonded washers are necessary when mounting hardware to an enclosure. If standard mounting hardware is used, the NEMA rating of the enclosure will no longer be maintained. Bonded washers have rubber gaskets that make a watertight seal around the drilled hole. It is also important to make sure the material used for the bonded washer matches the material of the enclosure. Stainless steel enclosures require stainless steel bonded washers.
