S-5! S Mini
The S-5-S clamp is an extraordinarily versatile clamp. It was created for popular snap-together profiles — including residential profiles such as Taylor Metal’s Easy Lock™ Standing Seam and the Firestone UC4. The S-5-S or S-5-S Mini can be used on horizontal seams under 0.54″ to avoid field crimping the seam.
