That pic was just sent to me from somebody else, who is very impressed with the product design and build quality.
nice...Which size would be appropriate for a solar mount install?

Model Cable Diameter Range (Inches) Dimensions (Inches)
RA-1 0.1 - 0.25 2.17 x 1.65 x 0.63
RA-2 0.27 - 0.35 3.23 x 2.44 x 0.95
RA-3 0.39 - 0.47 3.23 x 2.44 x 0.95
Here is a less expensive ($9.90) alternative that has very good ratings on Amazon.

 Instapark® IN-DW Surface-mountable Dual Cable Feed-thru

Sternwake, That  looks like a nice product but means drilling 4 holes in my roof. It reads as though it's made for a single wire too.

VJG1977, A cheaper 2-wire version but useless without the manufacturer giving  us a cable size range.

I'm going with a dual cable gland (what Guy is talking about but has two holes for two wires) in a 2x4x2 water tight electrical junction box and sticking the box as well as the solar panel brackets to the roof with 3M VHB 4930 tape. Only one hole through the center of the junction box to feed both cables inside.

Lowes sells this PVC Carlon Electric box for 5.79 and you'll need a 2X4 gasketed cover for 2.20

The product I linked in the OP is just a nice low profile streamlined pass through that isn't going to catch a branch.  Could be useful in some stealthier solar  installs 


I just have regular cord grips sticking the wires out perpendicular to my roofline and having to bend 90 degrees under my framed panel.

More links to similar products/ options would be good for those searching in the future.

I use these in half inch and 3/4:

Originally I just drilled a hole and used 3m5200

I used the 5200 to hold some wires to the roof.
yeah that 3M 5200 is some amazing stuff. I got some on my arm once and couldn't get it off. I scrubbed and scrubbed it took my skin off. highdesertranger
