Chris -
I personally like the Wiley Ground lug (http://www.we-llc.com/WEEB.html)
although it is a bit expensive. It bolts onto the rail via a 1/4" bolt in the
rail's top extruded slot.
I've seen too many loose lugs when using the 10-32 tap method, it's too easy to
strip the soft aluminum.

Long time reader, first time poster.
I was wondering if anyone has experience with grounding UniRac Sunframe
rails. We use lugs on our panels and typically place lugs on the rail
as well, attaching with a through bolt. We have also used a tap and a
ground screw, but none of these methods feel as good as the methods we
use for other racking systems.
Any experience would be appreciated.
Chris
