Enclosure Pedestals & Bases
Hoffman Pedestals enable many types of boxes and enclosures to be floor mounted. Two bases and four columns are available. Columns can be mounted on either base through the vertical column or directly to the enclosure. A cutout must be made in the enclosure if wires are to come through the column. Pedestal Extensions can be used with pedestals to provide an additional 6 inches of height.
Hoffman Pedestals With Legs are available in two heights with four die-cast legs that bolt to the vertical tube. The legs have holes for bolting the pedestal to the floor and can also accept casters in limited applications. Tapped mounting holes in the top of the pedestal allow attachment to an HMI base with swivel, swivel tilt, cutout or angle adapter.
Hoffman Bolt-Down Pedestals are available in two heights and tapped mounting holes in the top of the pedestal allow attachment to an operator interface base with swivel, swivel tilt, cutout or angle adapter.

Hoffman Stainless Steel Pedestals are 36 inches tall and provide optimal viewing and operating height. The tube is 14 gauge Type 304 stainless steel and cable access plate and leg levelers are included. Leg levelers can be removed for anchoring the pedestals to the floor. Stainless Steel Extensions can be ordered separately to provide an additional 6 inches of height.
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.
