The Gardco Mayer Applicator Rods & Jr. Drawdown Rods are round stainless steel bars tightly wound with stainless steel wire, also known as mayer rods, drawdown rods, and film applicators. The diameters of the rods and wires vary in size depending on type of application. The diameters of the wires, in the wound form, regulates the thickness of the coating. During the manufacturing process, tight tolerances are held along with strict quality control.
