[RE-wrenches] EnPhase/Racking Best Fit

[William Miller]

Friends:

The T-bolts scare me.  If you get them rotated fully, there is but a little 
nib on each end of the T that constitutes your entire hold down 
strength.  Fail to rotate them fully and your hold down strength is 
compromised.

DPW has a new approach I inspected at the SPI:  The hold down clip is 
indexed to the T-bolt.  The T bolt must be fully rotated before the clip 
can be lowered between the modules.  I find this way 
"more-better."  Another advantage to DPW clips:  they require 1/4" spacing 
instead of 1".

I prefer Unirac rail -- I might try substituting DPW hardware into Unirac 
rail.  Has anyone tried this?.
