Description: These beefy, bright red 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. The lid is secured with 6 4mm screws (included)

  • I am going to use this as a battery pac on my remote for my AVC entry!!!!

  • Hi , i am waiting to get one,before it arrives i would like to share this http://grabcad.com/library/caja-roja-sparkfun it is an approximate CAD model of the enclosure.

  • Can I have a bluetooth module inside and still get good signal?

  • This is a nice box, really solid. Mine came with only 2 screws, which isn’t a big deal. However, it’s really hard to mount an Arduino in, and I think I’m going to have to do some dremel work to fit a ScrewShield.

  • The 11/16/12 New Product Post video states that this box (and the related USB sealed connector and cap) is “submersible”. Does anybody have any feel for how deep this box might be submerged prior to leaking or other failure vector?

    • The IP65 rating is not a “submersible” rating. It is dust tight, and tested with water jets a minimum of 4.35 psi at 25 gallons per minute for 3 minutes minimum from about 9 feet away.

  • Just got my box. The internal mounting holes don’t really line up to anything useful. My UNO can orient with one hole but other configurations make it interfere with the walls/insert posts. It’s still a fine box, but I’m going to have to make a plate to go inside which I can mount to.

  • I see SFE has more important things to do than answer all the product questions. This would be a good item to use to put the UNO’s and shields in “out in the field.” BUT..would really like to know about the UV inhibitors. Must not have them if SFE won’t answer. That would be a negative for the product. Also how about even putting a UNO inside one. Dorje’s question was never answered and well as dbc’s. Must not be good for outdoor use. Hey Robert – how about doing an update on your post and maybe for us “builders” out here speck whether Arduino boards might fit inside. A bit of frustration out here as you can tell.. Oh well… back to Mouser I guess.

    • Hi, we don’t currently have the man power to check all the comments on all 3000+ products. While we do try to comment on things when we see them as you can see that might take a year for us to see them. If you have specific questions email our tech support staff (techsupport@sparkfun.com) and we’ll get back to you.

  • The dimensional drawing is excellent for this product. I wish we had that kind of information for all enclosures. Anyway, can anyone check if the long dimension of an Arduino UNO (the 2.7 inch side of the 2.7x2.1" board) fits in between the screw holes on the inside? The dimension is listed as 69mm on the drawing, which is 2.717", but the dimension on the drawing doesn’t go to the correct line. Also, is it possible to fit three Unos in side by side or maybe overlapping a bit? 3x2.1"x25.4mm/in=160mm, whereas the inside is just 152mm, but I’m not sure how accurate those Arduino dimensions are.

    I’m also interested in the dimensions of the label recess.

    Thanks! Appreciate it!

  • Weather tight! Excellent! This is my 40th year as a licensed ham, so I’ve spent my fair share of time scrounging or creating wx-tight boxen. @tpobrienjr excellent point on UV inhibitors. @SparkFun – did you spec UV inhibitors, or just red plastic? WX-tight w/o UV protection kind of misses the point.

  • What kind of plastic? ABS?

    Does the plastic have UV inhibitors in it (i.e. for outdoor application)?

    • Surfing the manufacturers website reveals that the material for the base and lid is high-impact ABS. It is IP65 rated, but no mention of UV inhibitors. It also says the screws are Stainless Steel and the inserts are brass, so that is at least hopeful for outdoor use. The gasket is apparently silicon, though I suspect they mean silicone ;)

  • Nice enclosure, especially for the price. I’ll definitely grab some of these for home automation projects.

    It looks like the top surface has a recess for a decal - is a dimensioned drawing available for that?

  • -1 for not having a clear cover that lets you read an LCD through it. :(

    • The proper application of cutting, clear plastic and hot glue can fix that.

    • You want an enclosure with a clear cover, that is waterproof, and that has 3mm thick sidewalls? That’s going to cost you a lot more than $7.95!

      Hoobert’s cutting, clear plastic, and hot glue suggestion will work in a pinch (no guarantees on the durability of the hot glue under UV exposure, though…). If you want a more professional solution, Hammond’s 1544 series has a clear cover but no flanges. It does have externally accessible mounting holes, though. Everest appears to have similar products.

      • “Hoffman Boxes” would also be a nice commercial choice. Any commercial/industrial electrical supply house should have them - but they are going to be pricey. I have used them outdoors, in washdown environments, and hazardous environments. They work well, but Hoffman charges accordingly. Best for use when someone else is paying.

  • baluns? not sure I’m familiar with that one….

    • And yet you have probably used them at some point in your life… like watching TV.

      Learning something new every day is what keeps this stuff fun. 50+ years doing electronics and still going.
