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.
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.
Thank you for your feedback, Edmond. We really appreciate you taking the time to share it. You’re absolutely right regarding the shipping on this order. There was an issue that caused the rate for this clamp to calculate too high. We’ve gone ahead and refunded the overage and corrected the setup so future orders will reflect accurate shipping.
Regarding the threading alignment, that’s not the experience we expect with S-5! products. We appreciate you pointing that out. If you’re able to share any photos, please send them to info@rapidmaterials.com so we can review and pass the feedback directly along to S-5! for further investigation.
Thanks again! We truly appreciate your continued business and are glad to hear you’ll be ordering again.
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.
