BUD Industries CU-234 Aluminum Econobox 4.68" L x 3.68" W x 2.21" H, Natural

Well constructed junction box. The device can be slid out the side of the box for troubleshooting or wiring. With a little bit of an adjustment to the placement of the instrument a 25 amp SSR would fit the box nicely. My 4 amp OPTO 22 SSR has plenty of room. The device sticks slightly outside of the box due to the angle of the side, but because of the recess in the lid it fits perfectly. The instrument I have installed is protruding 96mm inside the box.

The enclosure was easy to work with and sealed up very good to hold a circuit I made to fit inside the enclosure

This is a sturdy cast aluminum enclosure with a cover. I used it to enclose a 12 volt to 24 volt DC converter to run my wife's Omron portable oxygen concentrator while in the car using the 12 volt cigarette lighter outlet. I drilled holes for air input and installed a 30 mm diameter fan for cooling, which was probably not necessary as the same 250 watt converter I installed in the second car had no fan, just two cooling holes. The only problem with this case is that I had to cut the threads for the #6 machine screws holding on the cover as the aluminum was too hard for the screws to cut their own threads. For that problem I deducted one star. The MGGi DC Boost Converter Regulator also from Amazon fit nicely. The whole unit fits under the passenger seat with the two cords cut to convenient lengths for the connections to cigarette liter in the back and concentrator in the from. Although the Omron portable will work from direct 12 volts from the cigarette lighter socket, the 24 volts from the converter also allows the battery to recharge while the concentrator is on full output. Its is out of sight, but does look professional. If you decide to use this 250 watt converter and this box, just drill two 5/8" holes on both sides of the enclosure without the fan and it should work well.

It is made of thick aluminum. It is not a rectangular prism. Easy to drill, but difficult to cut.Great for a custom power supply or other electronic projects that need some RF shielding or cooling.

I made a Raspberry Pi Zero, HiFiBerry Hat, Volumio audio player that plays from local file share or internal USB sticks that holds over 500 albums in FLAC format. External antenna improves range. 5V buck converter allows the use of any power supply between 5 - 34 volt.Screws holes aren’t tapped, but included machine screws do the work nicely as they are harder than the softer aluminum.

After my project was complete I went to screw on the bottom plate only to find the machine screws supplied had the incorrect thread And would not thread in. After the rest of the project was finished I did not want to return the box And start over I am now trying to find screws that match but I’m sure they’re metric and will be hard to find

The box is a typical nice, sturdy aluminum box. My only complaint was that the screw holes in the box weren't perfectly tapped, or the screws themselves were somewhat imperfect, because the first few times they went in, I had to seriously wrench down on them. The screws basically had to cut the threads.Now it's perfectly fine though!

good boxes for those custom controllers ect.machines nice. doesn't ball up like some other brands.
