I'm installing a used RDAC-X in my firewall. It appears to require stand-off washers (conductive) or rubber bushings (insulators) between the RDAC and the firewall, or the soldier connections on the bottom of the RDAC will contact the firewall.
What is the appropriate material?
TIA, Eric

The RDAC was originally shipped with a set of metal stand-offs for this purpose.
I suppose anything that is mechanically sound will do...

Excellent. Thanks
