S-5-R465 Clamps

The S-5-R465 and S-5-R465 Mini clamps are created specifically to fit the Zambelli RIB-ROOF 465, McElroy Metal’s Mirage II, Rib Roof Metal Systems’ Rib Roof and similar roof profiles.

S-5-R465 Clamp

The strength of the S-5-R465 clamp is in its simple design. The clamps are uniquely designed with opposing setscrews to maximize holding strength. Go to the tools page for information and tools available for properly attaching and tensioning S-5!® clamps. The round-point setscrews do not penetrate the weathering membrane of the roof, nor damage the protective Galvalume coatings of steel panels. They will not cause scoring which can lead to roof material fracture or premature corrosion, including rust, thereby voiding the roof manufacturer’s warranty.

Installation is Easy

Partially thread all four round-point setscrews into the clamp by hand. Position the clamp at desired location along the seam with the bolt hole in the correct (upslope or downslope) orientation. Use a screwgun and the included bit tip to tighten the two upslope setscrews until flush with seam wall. Next, tighten the two downslope setscrews until flush with seam wall. Finally, tension and re-tension each of the four setscrews as the seam material compresses, i.e. tighten the first setscrew, then the second; then repeat until each setscrew achieves the recommended torque. When relying on published load values, setscrew tension should be verified using a calibrated torque wrench as indicated below to ensure the tool is consistently achieving the proper torque range. Once installed correctly, these clamps require no maintenance or re-inspection for the life of the roof.
For critical attachment applications, tighten the included M8-1.25 X 16 mm Hex Flange Bolt to 160 inch pounds (13 foot pounds).
