S-5-N Seam Clamp

Delivered what was promised

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.

A++++++

I have a copper roof with raised ribs and use the S-5! mountings to fasten my solar panels as well as my Ham Radio tripods. They are easy to install and have never failed.

Worked perfect for the roof mounting project. Great quality, good and strong. plus would purchase on the next project !!

Clamps originally sent were incorrect for my roof. However, they very quickly acknowledged error, authorized return at no charge, and replaced the order with a new, correct, one. Great response, great service.

Thank you for the prompt and accurate delivery

I was able to find the proper fitting I was searching for on the companies website. Checkout was quick and simple and the order was delivered on time. I will definitely search your website on any future materials needed.

Well made product, great price.
i suggest using an anti-seize product on the set screw, if you ever want to get it off in the future.
Stainless and aluminum make for a permanent bond of corrosion, have way too much experience with the such.

This is my second purchase. This order came with the clamping threaded holes and the counter divot in the clamping pieces not perfectly aligned. It caused the mechanism to bump the next row of panels up about a 16th of an inch. Not much, but not perfect as was my previous order. Shipping is also pretty high. Love the concept, and the parts are robust!
I will be buying more.

Same as review for full sized S-5-S. Excellent all the way.
p.s. These guys respond quickly to requests for information through their website.

I placed a tiny order for test items for an important job, and was treated like royalty! Great service and information provided avery step of the way.

Great customer service, fast shipping, good price!

For our local 1.5" standing seam snap lock 16" wide panels, these are incredible. We use them to mount shallow channel for solar panels. Perfect fitment and fast install.

These Seam Clamps work well on a 1-inch standing seam roof; they grip well and do not slide off like other clamps.

Great pricing and very quick delivery of my go to clamp system. (S5E). I've ordered several times and they're always delivered quickly and well packaged. Can't find a better price anywhere. I get them here cheaper than my wholesale metal supplier buys them. Thanks , Rapid Supply.

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

Great Service

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.

Bought these to clamp our Starlink base (built out of square tube stock) to a 1” standing seam roof. Works perfectly for the application. Wish they came in four or six packs but otherwise turned out excellent.

These things are heavy duty and work perfect on standing seam roofs for mounting about anything. Buy with confidence.
