It is 12 gauge steel, which is the heavier of the common back panel gauges and is what you want when you are hanging transformers, contactors, or loaded DIN rail rather than just terminal blocks. The panel weighs 65.037 lb on its own, so plan on two people to set it into a floor-mount enclosure.

White powder coat over steel. The white face is standard for control panels because it reflects light inside the enclosure and makes wire labels readable. You can drill and tap it in the field for your device layout; touch up any bare steel at the holes so the cut edges do not corrode in a humid or washdown area.

The AW6042P is listed to CSA C22.2, which is the certification specifiers on Canadian industrial control jobs typically ask to see on enclosure components.

Back panels like the AW6042P are ordered as a separate line item. Enclosures commonly ship as the box, door, and hardware only, with the interior mounting panel bought to suit the build. If you are quoting a 60x42 control enclosure, add this panel to the order or the panel shop has nothing to mount devices to.

A flanged panel has formed edges that stiffen it and stand it off the enclosure's rear wall, which keeps device screws and wire clear of the back and resists bowing when the panel is heavily loaded. The AW6042P is the large NEMA flanged style. A flat panel is lighter and cheaper but flexes more under load and offers no standoff. For a 60x42 enclosure carrying real weight, the flanged version is the one to use.

The part is B-Line AW6042P, a 12 gauge white powder coated steel back panel for large NEMA flanged applications. Order by that MPN to get the same panel already in service; the AW prefix with the 6042 size code is how B-Line identifies the 60x42 interior panel.
