Box 3.94 x 3.94 x1.97"

Yup... 94.8 mm x 100 mm for a board outline that will slip into the pcb slot in the base. Copied from a previous review... Trust but verify... Verified! It's exactly as you'd expect from the photos. I put a 94.8mm x 100mm PCB in it and it slid in perfectly. This is the perfect size enclosure if you have tall components and also want to keep the board size inside the 10cmx10cm limit to get really cheap boards from china.

With removable ends and top, projects can be mounted to the box and accessed with ease. Aluminum makes a great heat sink, and I mounted a variable voltage regulator on one end and two insulated female jacks on the opposite end, one for input voltage, and the second one for output voltage. Project was made for a specific voltage, so no access was necessary for voltage adjustment. The aluminum box is not sealed or waterproof, but project was made for in-house use.

So nice in person. The photos do not do this enclosure justice! Really adds a touch of professionalism to the project. Buy one and see.

They would sell more of these boxes, if you didn't have to buy one, just to get the inside dimensions.

I was pleasantly surprised that the body slides apart smoothly into 2 prices when the ends are removed, for easy access to parts I mounted inside. The sliding extrusions fit beautifully.

Perfect for small projects where a plastic enclosure may not be advisable (EMR issues etc). Material drills easily. Somebody had mentioned that a standard size of PCB board would slide into the internal slots - 94.8 mm - and it does with some filing down of the board edges - but finding such boards in the US was not easy. Newark (Farnell from UK), does have them.

Eightwood Aluminum Enclosure Electronic Project Box Case for PCB Instrument Amplifier DIY: Dislikes: 1. Top slides on and off so a panel has to be removed to take the top off. I filed what I'm calling the top, the larger part which has the socket slide groove, to remove the angular socket so I could pull it off without removing a panel. This way, just two screws then have to be removed which is better for quick access. Some may like that it slides on and off, but I prefer to easily be able to remove the top with the front and back intact, so wires and connectors are not moved. 2. Front/Back mounting holes don't align top to bottom -- I had to file the mounting holes so they line up with the threaded screw holes on the other parts. Two from side to side fit but not top to bottom. 3. You have to provide some rubber feet. Likes: It was just right for my project which was a TinySA Ultra spectrum analyzer tracking generator. I put a hole on the top to access the oscillator tuning power supply adjustment. Note: it is rather shiny. It looks like it was sand blasted and coated as it feels smooth with the sand-blast marks shining through.

Quick delivery and use.

Just as discribed .would buy again

This is an extruded aluminum box, comprising two halves that slide together and two end-plates that screw on. The fit and finish is good. We took off a star because one of the eight screw holes that hold the end-plates was not tapped. Luckily, I have the correct metric tap in the garage. We are using it to house two solid state relays; being aluminum, it will not only protect the operator from shocks, but it will serve as a heat-sink for the SSRs.
