Enclosure Floor Stands, Pedestals, Legs, & Casters
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.
Enclosure floor stands can easily be installed on most freestanding or wall-mount enclosures for floor mounting or to add additional height.
Enclosure casters are small swiveling wheels that can be attached to allow heavy enclosures to be easily moved or relocated.

Enclosure pedestals and bases are used to support an operator interface enclosure. They come with or without legs and heights varying between 6 inches and 41 inches. Swivel bases can be installed between the bottom of the operator interface enclosure and the pedestal. They are used to provide a machine operator a way to easily rotate an operator interface enclosure to a maximum of 550 degrees, resulting in a convenient operating position. Swivel bases can be locked in any position.
Combination swivel and tilt bases are designed for use between an HMI enclosure and the pedestal. They are used to provide a machine operator a way to rotate and tilt an HMI enclosure for safe operation and optimal viewing. The swivel feature allows a maximum rotation of 350 degrees and the tilt feature allows forward and backward movement up to 30 degrees from horizontal. Swivel can be locked in any position and tilt lock allows incremental adjustments.
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.
