RoofClamp RC Seam Compatibility

  • Made in America
  • Fast, effortless installation. 
  • Secure satellite dishes, roof walks, conduits, or HVAC lines. 
  • Doesn’t pierce or penetrate the panel. Won’t void the manufacturer's warranty.
  • Only requires 90-inch pounds of torque, almost half of what some other clamps require.
  • Preinstalled screws save time and money.

Attach almost any accessory or product to your roof without damaging standing seams or piercing panels with SnoBlox RoofClamps. This patented design fits over roof seams for a fast, effortless installation and will fit almost any seam. Ensure you won't void manufacturer warranties by piercing or penetrating panels on your roof with SnoBlox RoofClamps.


Unlike competing products, SnoBlox RoofClamps use a coarse-threaded set screw. This type of threading prevents set screw lockup, which means you can reuse the product. Most other products on the market need to be cut off with a grinder, but our clamp allows you to unscrew and reuse the clamp.


The aluminum RoofClamp utilizes three stainless steel cup-tipped screws.  The attachment of the clamp is in one piece instead of two and for extra strength, it has three set screws instead of just one or two. It is fast and easy to install, and will last the life of the roof. These two competitively priced models work on most of the same panels as the nine different clamps that are currently on the market. Three 1-1/4” x 3/8” cupped-tipped set screws One 3/8” threaded mounting hole on top. The RoofClamp RC and RCT mounting clamps have been shear tested and tensile tested by a nationally known testing lab.

Safe for Roofs

This patented design fits over the seam.  The clamp is one piece and does not require seam feeding up the panel. The RC model is designed to fit most seams up to 1" wide. Interior dimensions are 1" wide by 1" high. The aluminum Roof Clamp utilizes a stainless steel cupped-tipped screw that does not pierce or penetrate the panel; therefore, it will not void the manufacturer warranty.

The following warranty is made in lieu of all other warranties expressed or implied. Recommendations for proper use of the product are based on tests believed to be reliable. Any goods proven to be defective due to materials will be replaced, or purchase price refunded, but in no event shall the manufacturer be responsible for damages in excess of the purchase price. User shall determine the suitability of the product for its intended use and assumes all risks of its use or handling.

    I have tried numerous clamps on the market and found that the RC clamp sets straight when installed, and I like the idea of 3 contact points with no damage to my roof. Don't have to hit these on very easy installation. Well built and with stainless hardware. NOT A CON BUT A DESIGN CHANGE. The only thing I wish that was different is that the bolt on the top had a bonding serration on the bottom of the head instead of a washer with a wider base. Will defiantly buy again. Thank You Rudy
