With SnoBlox RoofClamps, you can attach practically any accessory or product to your roof without damaging standing seams or puncturing panels. With its innovative design, practically any roof seam can be attached to for a quick, simple installation. With SnoBlox RoofClamps, you can make sure that puncturing or penetrating roof panels won't void manufacturer warranties.


SnoBlox RoofClamps feature coarse threaded set screws in contrast to rival clamps. Because of the way the RoofClamp is threaded, set screw lockup is avoided, allowing for reuse. Our clamp, in contrast to the majority of other clamps on the market, allows you to unscrew and reuse the clamp.


Three cupped-tipped screws made of stainless steel are used with the aluminum RoofClamp. The clamp's attachment is made of a single piece rather than two, and it contains three set screws as opposed to one or two for added sturdiness. It will endure the entire life of the roof and is quick and simple to install. These two competitively priced clamps work on the majority of the same panels as the nine various clamps already available. Three cupped-tipped set screws measuring 1-1/4" X 3/8". On top, there is a single 3/8" mounting hole. A nationally recognized testing facility has shear and tensile tested the RoofClamp RC and RCT mounting clamps.

Safe for Roofs

This patented design top mounts to the seam. The RoofClamps does not need to be fed up along the roof seams. Most seams up to 1.1" wide can accommodate the RCT model. The interior measures 1" wide by 1 3/8" high, with a 1.5" wide by 0.5" high seam channel. The majority of metal panels with T-seams and bulb seams can be used with this clamp. The roof's manufacturer warranty will not be voided because the aluminum Roof Clamp uses three stainless steel cupped pointed screws that do not pierce or penetrate the panel.
