Rapid Materials' S-5-N Seam Clamp was exactly what I needed to easily mount four 200W solar panels on our 12' x 10' backyard shed's metal roof. Installation took minutes, and love that these don't damage the actual metal seams. Even better, the Rapid Materials team member helped me quickly pick the right model of clamp after measuring and sharing a photo of the seam. Having never mounted anything on a metal roof before, I was delighted with how simple this was, and have been referring neighbors to Rapid Materials accordingly.

They work great. The web site easy to use parts came quickly.

The items were shipped quickly and arrived on time. Very satisfied with the delivery.

Another easily placed, promptly delivered order. And competitively priced!

Make sure you know the shape of your metal roof. Once you know that, buy the appropriate S5! clamp style. I had to go through two different varieties to get the right one.

I used four of these and two cross members to attach my Starlink antenna. It was simple and straightforward, and the connection is robust for me not to worry about it at all.
