After the second (upper) rod has been fitted through the SnoPosts™, the clamp's screws can be tightened. Using an Allen wrench attachment tip for a 1/4" drive screwgun, tighten and re-tighten setscrews as the seam material compresses. (These screwgun tips are available from your S-5!™ product distributor.) On low seam profiles, a 4" bit extension on the screwgun will facilitate this work.
CAUTION: Holding strength of S-5! clamps is highly dependent upon setscrew tension. Consult your distributor or the S-5! website for screw tension when relying on tested holding strength. Most industrial grade screwguns are rated at 115 inch pounds tightening torque and will deliver between 115 and 150 in lbs (13-17 Nm) at the highest torque setting. These tensions will not harm most panel seam profiles and materials. For critical installations, screw tension should be periodically verified as tested using a torque-indicating wrench.
