Enclosure Gland Plates
Enclosure gland plates provide a controlled and removable solution for cable entry and exit while helping maintain the environmental integrity of industrial enclosures. RSP Supply offers a wide selection of Hoffman enclosure gland plates, including cable entry gland plates, disconnect gland plates, vented (filtered) gland plates, internally mounted gland plates, solid gland plates, EMC gland plates, and FUSION gland plate systems. These components are designed to simplify enclosure modifications without compromising NEMA ratings.
Hoffman gland plates are commonly used with subpanels or rack angles and typically feature adjustable plate designs that allow flexible cable routing. Many configurations include conductive fabric-over-foam or sealing gaskets to support proper environmental sealing. Solid gland plates and EMC gland plates are suitable for use on 100 mm solid bases, plinth bases, mobile bases, and transportation bases, and may also be installed without a base when levelers, casters, or frame feet are used. Some solid gland plates can be rotated 180 degrees to allow front or rear cable entry.
Filtered or vented gland plates are designed for use with vented plinth base covers and include multiple adjustable plates, integrated filters, and retaining rails to allow airflow while managing cable entry. Gland plates are also useful for covering unused cutouts left by removed equipment or adapting enclosures to new external devices with smaller footprints. When properly selected and installed, gland plates help preserve enclosure protection and simplify ongoing system changes.
More Information about Enclosure Gland Plates
Hoffman EMC Gland Plates can be used with subpanels or rack angles and consist of a base mounting surface and two adjustable gland plates with conductive fabric-over-foam gasket for cable entry.
Hoffman Filtered (Vented) Gland Plates are only used with Vented Plinth Base Covers. The plates can be used with PROLINE subpanels or rack angles. They consist of a mounting base, three adjustable plates for cable entry, a filter and filter retaining rails.
FAQs
Q: What is an enclosure gland plate used for?
An enclosure gland plate provides a removable and configurable cable entry or exit point while helping maintain the enclosure’s environmental rating.
Q: Can gland plates help maintain NEMA ratings?
Yes, when properly installed with compatible gaskets, conduit hubs, and mounting hardware, gland plates can help preserve the NEMA rating of an enclosure.
Q: What types of Hoffman gland plates are available?
Hoffman gland plates include solid gland plates, EMC gland plates, cable entry gland plates, disconnect gland plates, vented (filtered) gland plates, internally mounted gland plates, and FUSION gland plate systems.
Q: When are vented gland plates used?
Vented gland plates are used with vented plinth base covers to allow airflow into the enclosure while still providing controlled cable entry and filtration.
Q: Can gland plates be easier to modify than enclosure walls?
Yes, in many applications gland plates are easier to drill or punch than enclosure walls and can help retain enclosure certifications that might otherwise be lost.
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.
