Bud IndustriesAC-424 Aluminum Chassis 12" L x 8" W x 3" D, Natural

Bud quality has been built exactly the same way for over 60 years. These make excellent hobbyist electronics project enclosures. I really don’t think it’s possible to improve these.

This company makes the best Aluminum Chassis we've seen, they carry all kinds of sizes and shapes. A really cool Aluminum chassis that may be used for most any project.

Will use for tube projects.

Nothing wrong with the chassis, but Amazon recommends BUD Industries BPA-1519 Aluminum Chassis Bottom Plate as the cover for this box. The pre-drilled holes between that cover and this box do not match.

BUD products are always good quality

I was very happy to find that this box was square, rigid, and sealed enough (with no daylight in the corners) to function as a low profile lighting bracket for the back of a police motorcycle. I should have roughed up the finish before priming and painting instead of just degreasing, but that's no fault of the product. This was priced similarly to other plastic project boxes of the same size, and all I did to make it waterproof was add a foam tape gasket between the box and lid. I'm happy with how it turned out.

Made a cnc controller box and working out just fine.
