If this helps, I just installed a system and used 3 different size loop clamps ( del city) which worked really well.
I used 3/8" for single wires, 3/4 for 2 wires and 1" for 3 and also for the connector, worked really well, made it all very clean. I attached them with SS tek screws into the rails. jay peltz power On Oct 20, 2010, at 9:40 AM, Mark Dickson wrote: > Just finished one. . .
