We have used these for years. They work better than wire ties, but the rubber liner deteriorates over time, so install them as if there is no rubber protection on the loom clamp.

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.

Just finished one. . .  Direct Power recommended drilling and bolting directly to the aluminum rails--easy and solid.  Although, I was not happy about all the wire management that went into it though.  Sure would be nice if somebody came along and made some integrated wire raceways!!!
It was amazing how many blank stares I got from racking manus at SPI, when I asked them if they had any in the works.  Most just kept pointing to their wire clips and pretended not to know about the NEC requirements.
