  • Very sturdy watertight box, good value
Size: 3.27" X 3.19" X 2.2" Color: Black (1 pack)
I use such boxes for watertight connections on boats. This manufacturer happens to have many, many different sizes and configurations, and the one I chose fell right between two sizes offered by another manufacturer. In other words, the size (an oddball size) of this box was “just right”. In addition, this box is extremely well-made. It comes with a silicone rubber gasket to install on the lid to ensure waterproof integrity. Much to my amazement, it also came with FOUR cable glands, two each of a size, so any cable entering the box can be sealed off to prevent water ingress. The screws are genuine stainless steel, an important feature for wet locations. The 4 pre-drilled holes for mounting the box are each tucked in a corner, and “live” outside the waterproof section of the box so no caulking of the mounting holes is necessary. The 4 mounting holes are completely independent of the watertight compartment. Very clever indeed! There are 4 shouldered areas inside the box which will accept small (probably #6) sheet metal screws for mounting a terminal strip or other electrical items (relays, etc). It’s rated IP65 for water resistance, and I absolutely believe it. This rating means it is dustproof & can resist low-pressure jets of water (like rain or splashing water). I’ll definitely be buying more of these boxes in the future ... show more

  • I trust the quality of this box to safely maintain the integrity of my electronics & recommended it.
Size: 8.9" x 5.7" x 3.1" Color: Black (1 pack)
I made good use of this black ABS project box. It appears to have a good weather protection from its included seal too, which is just what I needed. I also appreciated getting some fittings included within the box for my low voltage multi-wire cord connections. I was able to drill several very clean holes for cabling, switches & LEDs and do some odd shaped cuts with my Dremel tool. It cut very nicely. No chipping or other issues that one might experience with a lessor (non ABS) box. This is the plastic material that is good for this sort of thing. I am quite satisfied as it worked beautifully for my project! I added this box to my Champion inverter so that it would be fully remote control via a series of RF relays all triggered by a simple 4-button key FOB. There are 4 different colored LEDs on the panel of the box with a push-button on/off switch in the center. Thanks to this box I can now control Start, Stop, Choke & Eco Mode and know exactly what is going on with it without having to go outdoors when using the inverter as a whole-house power backup for common winter power outages. I trust the quality of this box to safely maintain the integrity of my electronics and recommended it. Here are a couple of pics of the box on my new 'Wireless Inverter" project. (with FAT tires too. Oh yeah!) ... show more

  • Versatile water tight project box available in many different sizes! Will buy again!
Size: 8.9" x 5.7" x 3.1" Color: Black (1 pack)
Awesome project box that was perfectly sized for the circuit and install that was planned. It was very easy to cut Acrylic panels to hold electronics because the listing had accurate dimensions! The thickness of the Plastic was great and the weathertight gasket provides a positive seal that has kept the build nice and dry and the electronics well protected! Included were high quality stainless steel screws that provide a a great look and will not corrode over time. I ended up fixturing it down to my cnc to carve holes to accommodate led holders. I scratched it during manufacturing and it buffed up nicely back to a high polish! This case has held up to the elements in the summer heat, rain and imagine it will do well in the midwest winter. I will be using these boxes in the future for many other projects! ... show more

  • Good quality, low price. Great combo!
Size: 3.9" X 2.6" X 1.9" Color: Black (2 packs)
Yeah, I like and use these boxes for various electrical & electronic projects. They can be drilled, carved & etc for any purpose necessary to integrate into a project because they're rigid but with some pliability, and tough too! I usually have a few around of different sizes. If an idea pops up, I check my supply. Possibly the best feature is economical pricing. This box also comes with two cord glands, and two plug bosses, with caps. Really great additions--especially for the low price. I'll certainly buy more in the future, (well, I'm 81, so . . .) ... show more
