Standard #6 countersunk machine screws hold the cases to the rails. Rails
can be made out of whatever you choose. aluminum extruded angle stock works
well and you can tap it or use thin angle and mount clip nuts so you can be
less precise in your drilling. Cut a thin .020 support to run from the top
hole (the upper screw holes of whatever your top radio is) down to the rear
support of the lowest radio to hold everything up.

Greg:
Here's how Fabian suggested I install my stack. It worked like a champ and was
simple.
1. Install all of the backplates to the cases, and then fully install radios in
the cases and snug them in.
2. Line up the front of the faces vertically, I used a carpenter square to ensure
they were alligned.
3. Carefully wrap the stack with duct tape to hold the cases together with the
faces aligned. An extra set of hands helps considerably.
4. Remove the radios and the backplates leaving the taped up stack as an assembly.
I guess the backplates can stay on unless they are prewired, you don't wan't
the harnesses pulling and getting in the way when installing.
5. Now you can put the stacked racks into the panel using .063 or larger angle
along the sides. Flush rivet the angles to the panel. Drill the angles through
the cases for #6 countersunk screws. This is the only difficult part. I ended
up marking the holes from the inside and removing the stack to drill the angle.
The radio instructions state to have the ends of the cases flush with the front
of the panel. This is not necessary. The cases might not all fit the same so
your goal is to have them all extend the same distance. The tape method allows
you to easily do this. Next, adjust the depth of the stack to make sure the screw
holes in the boxes will fall correctly in the mounting angles to provide
proper edge distance. Again, this is also more important than having the cases
flush with the front of the panel. In my case, I used the Affordable panel which
is .090 thick with a subframe that is also .090 thick. That's a whopping .180
in thickness. If I had tried mounting the cases flush, the screw holes would
have aligned with the perpendicular portion of the angle.
6. Dimple the holes in the cases as necessary if you can, countersink the angles.
Screw through the cases and angles and lock them with the method of your choice,
anchor nuts, nuts or tapping. I chose regular lock nuts because I have the
3-piece modular panel which will provide sufficient future access.
7. Strap the racks together near the middle or back to support the boxes. If your
holes are good and your screws are tight, the cases will tighten up in a rigid
box structure.
8. Install the backplates and insert the radios. You faces should line up nicely.
Vete76:
The radios do come with the installation hardware as indicated. It's defined differently
than you may think. Installation means installing the the backplates
to the cases, including the connectors and pins. Mounting hardware is peculiar
to each installation and is provided by us.

All,
Due to the large amount of responses, I can't respond to everyone
individually. However, rest assured that all of the responses were read and
very much appreciated. What did people do 20 years ago wthout a resource
such as this?
Anyways, i've decided to move forward with the simple Aluminum angle
technique. It's cheap and i have the stuff to complete it tomorrow. Thanks
again to everyone that responded.
Greg
