nVent Hoffman P2BGPI66 Internally Mounted Gland Plate The internally mounted gland plate functions in a similar manner as the standard gland plate: facilitating cable passage into an enclosure, while maintaining NEMA 12 environmental rating and maintaining the ability to support the weight of a person. Where the internally mounted gland plate differs is in installation. The standard gland plate requires access to the bottom of the enclosure to affix the solution, while the internally mounted gland plate is secured to a series of brackets installed from inside the enclosure. This solution is great for applications where lifting capability is limited, or after enclosure population when access to the bottom of the enclosure is limited.
