Enclosure - Aluminum (120x94.5x34mm)

These are our large, beefy aluminum enclosures, which have been built tough enough to withstand a truck. This 2mm-thick, die-cast enclosure is rated IP54 against dust and splashing water. Because it's aluminum, it's easy to cut and drill so that you can add LCD screens, buttons and cable connections. If you want to "pretty up" your project, hit this with some fine-grit sand paper and buff it or just spray paint it!

These enclosures are perfect for producing "stomp box"-style effects pedals. Try combining this with a stomp switch and some of your own secret sauce circuitry to build a sweet custom pedal.

The lid mates nicely to the top of the enclosure and is secured with 9mm long #6-32 screws (included). This aluminum enclosure version features a smoother metal finish as well as a more structurally sound design.

    Your misuse of units of measure is annoying. You give the dimension in metric units, but do the screw in UTS which is inch-based and then as a final insult give the screw length in mm. ARGGGH!

    I'm guessing that since it's a UTS screw that the box is actually meant to be measured in inches, but that there's some kind of conspiracy to deny inches in favor of metric in spite of the fact that 350 million of your closest potential customers use inches. Without debating the merits of the 2 systems, how about you pick one (either one) and stick with it for your ad copy? if you're going to mix and match, how about giving the complete set of dimensions in both?

    PS - there are 2 types of countries on this planet, those that have landed a man on the moon and those that use metric

    Are the dimensions internal or external?

    • Member #313481 / about 8 years ago / 2

      External. Wall thickness is around 2.2 mm.

    Screws too small.

    Does anyone have experience with Wifi signal reception by a device inside these boxes? I'm thinking of using one with a Photon wifi board, but I'd like to make sure the aluminum won't block the signal.

    • CF / about 8 years ago / 1

      Metal of any kind (including aluminum or plastic that has a metal coating) will block WiFi or any other radio signal. If you put a Photon inside one of these you will need to put an antenna on the outside of the box. An antenna like this one would be easiest to connect, but there are other options.

    Do you have any idea what aluminum alloy is used in this box? I like to anodize and dye many of my projects, so I always use 6061 aluminum.

    • Member #313481 / about 8 years ago / 1

      I tried anodizing it. it turns dark grey as is common for cast aluminum parts. It's definitely not 6061 or any other kind of easily anodized alloy. It's cast, so it likely contains a lot of silicon.

      • Member #430904 / about 7 years ago / 1

        Thank you for this clue. I wasn't very familiar with casting alloys, but probably it's 4041 with a high silicon content as you say, and poor for anodizing.

Good for the Money

Decent quality, but two of the boxes I got had machine screws which were too small. Joelle in customer service was great about getting me the correct ones.

The finish is kind of rough and the boxes will need to be painted but they are about half the price of other boxes. They are a good deal for the money. I'm happy with my purchase.

Just what I needed!

The size was right. The price was surprisingly low. And when the unit was received, the fit & finish was found to be very, very good. All edges were clean and both pieces mated true.

Extremely pleased.

It's a box!

This is a good solid enclosure. Easy to modify with a titanium drill bit or dremel tool. The walls are thick enough for tapping for 4-40 risers, but you will need to trim the excess that sticks out. I suggest mounting the pcb on the lid. I also used the body piece to mount other hardware. I bought 2 just-in-case, since they are inexpensive, but I was happy with my first attempt.

Excellent product

But the issue is the FedEX sure post shipping. Transit took around 10 days while the package went from small cities through out NC and SC- one city per day. Seemed to take forever. If shipped by regular USPS it would have been less than half the time.


It's a really great deal.

Solid 1590BB enclosure for about as reasonable as you can find one!

Boxes for my projects at Sparkfun!

Very fast and accurate delivery I was in need of die cast aluminum boxes and for my surprise Sparkfun was an affordable source for them Thanks
