The S-5-R465 Mini was created specifically to fit the Zambelli RIB-ROOF 465, McElroy Metal s Mirage II, Rib Roof Metal Systems Rib Roof, and similar roof profiles. The S-5-R465 Mini replaces the S-5-R Mini, proving to have more than three times the holding strength. The clamps are uniquely designed with opposing setscrews to maximize holding strength. The S-5-R465 Mini is a bit shorter than the S-5-R465 seam clamp, having only one setscrew on each side rather than two. The mini is the choice for attaching all kinds of rooftop accessories: signs, walkways, satellite dishes, antennas, rooftop lighting, lightning protection systems, solar arrays, exhaust stack bracing, conduit, condensate lines, mechanical equipment just about anything!
S-5! Mini clamps are not compatible with, and should not be used with, S-5! SnoRail /SnoFence or ColorGard snow retention systems.*
If you are using S-5! ColorGard, you should use the S-5-R465 seam clamp.
The S-5-R465 Mini clamp comes complete with two  3/8-24 x 0.50" setscrew. All hardware is stainless steel.
The Hex bolt is no longer standard with S-5! mini clamps. Options are:
- No bolt
- 16mm (5/8″) M8-1.25 Flanged Bolt
- 20mm (7/8″) M8-1.25 Flanged Bolt
- 40mm (1-9/16″) M8-1.25 FlangedBolt
The S-5-R465 mini clamp has been tested for load-to-failure results by an independent lab.
Install the S-5-R465 Mini 1 1. Partially thread the setscrews into the clamp by hand. Position the clamp at the 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 one setscrew until flush with the seam wall. Then tighten the other setscrew until flush with the seam wall. Finally, tension and re-tension both setscrews as the seam material compresses, i.e. tighten the first setscrew, then the second; then repeat until each setscrew achieves the recommended torque. Screw 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).
