It's cosmetic. It covers the #2 Roberts square drive screws that attach the aluminum "J" channel (gutter) in place. The aluminum "J" channel is what secures the TPO roof membrane to the sides of the trailer FILON wall. All the vinyl insert does is "hide the screws" which will rust and stain the trailer sidewall if not covered and protected from the elements. It serves no "functional" purpose other than cosmetic covering of the screws.....

Be sure you order the correct width. I'm guessing it's 1", but it may be 7/8".
