Hammond perforated subpanels provide a surface to install electronic or other devices in the enclosure without compromising the NEMA rating. The perforations allow self-tapping screws for mounting lightweight components. Perforated subpanels sell separately in various height and width dimensions, in carbon steel with gray powder coat finish.
Subpanels are included with many of the Hammond industrial enclosures. Subpanels not included are purchased separately. The specifications table for each enclosure family lists the part number of the subpanel that goes with each enclosure.
