<br><br>2 points:<br><br>1) For the sake of clarity: there are WEEB <a href="http://www.we-llc.com/Datasheets/204-0404-000003.pdf">LUGS</a> and WEEB <a href="http://www.we-llc.com/Datasheets/204-0404-000007.pdf">CLIPS</a>. WEEB Lugs are comprised of very robust tin-plated copper lugs, stainless steel hardware, and the actual WEEB, which is the stainless steel nippled "washer" that pierces aluminum anodization. WEEB Clips are simply stainless steal nippled washers that are installed between module and rail that form a bond, theoretically eliminating the need to bond the module to a ground wire, so long as the rails are properly grounded.<br>
<br>2) My biggest concern with the WEEB Clip is that the moment a top-clamp is loosened the module is no longer grounded!!! To me that is not a good grounding method. Mr Wiley is obviously a talented inventor and he makes a strong argument for the quality of the bond that the WEEB Clip provides when the clip is installed properly and all mounting hardware is properly torqued. What I don't understand is the argument that this is as safe of a product as a properly installed outdoor rated lug for the service tech who has to work on that array. <br>
<br><br>A tin-plated copper lug with a stainless steel set screw will last. A service tech working on a faulted array that was grounded with WEEB Clips might not.<br><br><br><br>Andrew Truitt<br>Free agent<br>Golden, CO.<br>

Hopefully any crew installing PV, and familiar with this debate (which they should be) can easily distinguish between the GBL-4 and the GBL-4DBT. The weight difference is quite noticeable. If it feels light for its size, it's aluminum, dont use it!!! If it has some distinct weight to it, then it's most likely the copper DBT, giv'er!<div>
