Pomona 2901 Shielded Aluminium Enclosure

The Pomona 2901 is a shielded aluminium electrical box finished in blue enamel. It measures 4.25 inches wide by 2.64 inches high by 1.71 inches deep and includes eight steel #4-40 screws for the screw-on cover. This enclosure suits engineers and technicians who need a compact, shielded housing for sensitive circuits.

For shielded bench prototypes, not outdoor mains

The box is designed for indoor electronic assemblies that benefit from aluminium shielding and a screw-secured lid. It is not rated for outdoor exposure, wet locations or high-voltage mains distribution, so installers needing weatherproof or conduit-rated enclosures should look at other product lines.

Compact internal volume for small PCBs

The internal cavity comfortably accommodates small printed-circuit boards, terminal strips or sensor modules within the 1.71-inch depth. Larger assemblies, multi-board stacks or components requiring generous wiring space will exceed the available volume and require a larger enclosure.

Questions about this item

What mounting hardware must I already have to secure the Pomona 2901 box to a surface?

The box includes eight steel #4-40 x 1/4 in screws for the cover; you will need separate fasteners suited to your mounting surface.

Can I reuse my existing #4-40 screws with the shielded aluminum enclosure?

Yes, the cover uses #4-40 threads, so compatible screws you already own will engage the enclosure correctly.

How do I verify the shielded aluminum box is properly closed after installation?

All eight included #4-40 x 1/4 in screws should be fully seated and the blue enamel cover sits flush against the 4.25 in by 2.64 in by 1.71 in body.
