The Four bottle Klamp-It ASME/DOT/UN Bracketing System is an Ultra-Compact Klamp-It ASME/DOT/UN bracketing system which allows for either horizontal or vertical mounting of 4 cylinders while taking up only 3/8” of additional space for the hardware. The close coupling system allows for side by side cylinder mounting to minimize space requirements. Features removable sections that allow for easy cylinder removal or replacement. All brackets are constructed from premium high strength 12 and 14 gauge stainless steel and fitted with 1/4” stainless steel mounting plates and 3/8” stainless steel hardware. Augmented with traction materials to assure minimal cylinder movement after mounting.
