This all steel construction bracket is reinforced with vinyl edging to guard and protect the cylinders while providing extra grip. Epoxy powder-coated painted steel assures long service life and provides better chemical resistance. The straps and cinch-style buckles are the primary means of support as they tightly and securely hold the cylinders to the bracket. The polypropylene support straps are 1.5 in. wide by 54 in. long with steel cinch buckle that rates a robust 1200 PSI strength. Supports hold cylinders from 4 in. to 12 in. in diameter. Optional 14 in. Chain Set - Model G105 - PN 4302652.
