This box is all aluminum
construction and it looks to be 1/16" inch thick. It has a
black tube guard that stands up on 1 1/4" hex standoffs.
The black tube guard mounts to the standoffs with two #6
screws. There is also an internal hex standoff that
supports the center section between the two tube holes. It
comes with a package of chassis screws and rubber stick on
feet.
Hole sizes
1 = 5/16", 2 = 1/4", 3 = 3/8", 4 = 1", 5 =
1/2"
There is also a 15mm power receptacle hole on the left side
that is not visible in the photo. This would be for a
female wall wart plug receptacle.
The small holes
next to 1 and 3 is where the anti rotation tabs on Alpha
pots go.
