This is the Big Red Box! These beefy, bright red, flanged, plastic enclosures will give your widget the protection (and attention) it deserves. You've probably seen these used to enclose radio equipment or antenna baluns as they can be secured to a pole using U-bolts (not included). At about 3mm thick, this 74x158x90mm enclosure has plenty of space for gizmos, gadgets, widgets and doohickeys. The mounting flanges extend 19mm from either edge with two 50mm-spaced 7mm diameter holes.
There's a rubber gasket around the inside of the lid which forms a dust and moisture resistant seal when the screws are tightened down making the Big Red Box essentially weather/water proof. The lid is secured with six 4mm screws (included).
Whether it's for assembling a kit, hacking an enclosure, or creating your own parts; the DIY skill is all about knowing how to use tools and the techniques associated with them.
Skill Level: Competent - You might need to break out the power tools. Nothing beyond a power drill or rotary tool should be required, but you might have a hard time with just a screwdriver and hammer. Cutting holes into plastic or metal might be required.

Sturdy construction, bright red and overall a great enclosure. What I would really like is a 1/2 size Big Red Box, that version I would buy more often as most of my projects don't require anything this large. Just a suggestion.

I have ordered many of these enclosures, and they're great for just about anything that needs a case. Very durable, and a great price compared to other competitors!
Just utilized the Red Box enclosure to house relay equipment for prototype wireless boat lift control module. Plan to use Red Box for production version of wireless boat lift control as well. This enclosure is very well constructed and easy to machine on bench milling machine. Sparkfun rocks! (I would like to send Sparkfun a photo of the Red Box after it has been modified to attach to my posting. Please advise if interested.)

This is a good solid enclosure. The one challenge is the thick plastic needs to be cut slowly if you cutting openings or it will melt closed again. It is also thick enough that you may need to shave the surface to add things like female audio jacks made for thinner enclosures.
It's a good box, thick and solid, but not too hard to cut.
I wish Sparkfun would offer a mounting plate that matches the internal mounts (I think they match some boards that Sparkfun sells, but just selling an acrylic or metal plate would be nice).
It's large, sealed and drills/mills like a dream. Doesn't Crack or splinter when dropped. Works well with the add on protoboard.
Not flimsy, good dimensional control.
Be sure to use slow drilling and machining speeds to avoid melting..
A couple of smaller options would be nice..
Using it to protect an outdoor Arduino that's monitoring my pool equipment 24 hours a day.. Pleasant surprise to find that the box is translucent so that I can see the flashing LEDs at night which confirm that it's operating fine.
Nice made box. Needed about 5mm more width but all in all a nice box
It's a perfect match with your [Big Red Box] Proto Board. Together they are exactly what I was after. I have used other boxes before, but always had to adapt others' boards to fit. Thank you :)
Just beware; use the dimensional drawing, not the STEP file. I think the STEP file is off as mine was asymmetric.
This is my favorite enclosure; it's usually kinda big though. If Sparkfun offered smaller versions of it (like half the size) I'd definitely go for that!
I typically make control panels out of 30.5mm pushbuttons and this works great for that purpose. Can fit two of the buttons on the panel and it looks very clean and professional. The plastic this is made out of is incredibly sturdy. It's actually somewhat difficult to cut into but makes for a really great housing for a project. Would be nice to see these in a variety of colors besides bright red.
