Milbank A-HSPB – Frequently Asked Questions

1) Can the Milbank A-HSPB hole seal be used on outdoor electrical equipment?
It is built for enclosure use where environmental protection matters: steel body, ANSI 61 Grey finish for corrosion resistance, and a rubber gasket at the seal face. Typical placements are utility meter enclosures, outdoor electrical equipment, and industrial control panels. Note the A-HSPB is not UL listed, so if your specification calls for a listed closure on a listed enclosure, this is not the part.
2) How big is the Milbank A-HSPB hole seal, and what size opening will it cover?
Overall size is 0.5 x 1.5 x 1.5 inches, with the 1.5 inch dimensions given as height and width and 0.5 inch as length. That 1.5 inch square footprint is what has to overlap your opening, so measure the hole and confirm the plate has bearing surface all the way around before ordering.
3) Will the Milbank hole seal match the finish on my existing gray meter socket or panel?
Finish is ANSI 61 Grey, the standard gray used across utility meter sockets and electrical enclosures, so it blends with equipment already carrying that finish. For a property manager patching openings across a group of buildings, that means one part keeps the appearance consistent.
4) Can I install the Milbank A-HSPB hole seal without tools?
Installation uses a gasketed pushbutton wing nut, so it hand tightens from the accessible side. That also means it can be backed off later if the opening has to be reopened for a conduit run, which is the practical difference between this and a weld plate or a pop-riveted patch.
5) Does the Milbank A-HSPB come with a gasket, or do I need to buy one separately?
The rubber gasket is included with the seal, so nothing else is required to close the opening. No sealant or separate washer kit is needed for the connection.
6) Is the Milbank hole seal a knockout closure, or something different?
It is a gasketed closure assembly, not a knockout. The product data lists knockouts as FALSE, meaning there is no pre-scored opening in the plate itself; it is solid steel intended to seal an existing hole rather than provide a future entry point.
