FWIW, I just use a 1/8" thick x 3/4" wide aluminum bar
stock from the hardware store. Goes along the back
of the desk (near the top) and is periodly tapped for 8/32 screws
to accept AL/CU rated "spade" lugs that connect to the
various equipment "boxes" with ~1/4" braid. Then the strip is
connected to the station ground. Works for me.
