Camco Gray RV Party Light Holder - Easily Slides Into Awning Roller Bar Channel, Each Hanger Supports Up to 15 lbs - 7 Pack (42693)

I'd also like to know the thickness/width, because i want to use them for the awning on my house. i think the tract may be wider than a rv tract.

what is the diameter, of the ends. the fit is important. not all rails are the same my rail is 1970 model and dont want a sun shade to pull through.

Are there any nonmetal light holders designed for vinyl siding?

What size are s hooks to buy replacements?
