nVent Hoffman P2BGPV126 Vented Gland Plate The Vented Gland Plate is used in conjunction with the Vented Plinth Base Covers to passively cool electronics within an enclosure, while maintaining the NEMA 12 rating. The Vented Gland Plate is constructed in a similar manner as the standard PROLINE G2 Gland Plate, but in place of a number of the plates is an aluminum filter, or combination of filters, protected on the top and bottom by vented plates that facilitate air passage. Each gland plate solution has a single adjustable foam-gasketed gland that permits cable entry into the enclosure. Although the solution is robust, it is not recommended to stand directly on the vented plate/filter.
