[RE-wrenches] grounding UniRac Sunframe rails

[August Goers]

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.

Wrenches

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
