Product Overview
Avtek™ SuperSpru™ Runner Bars have a specially designed solid center, which acts as a reservoir to promote unrestricted metal flow from the button to the distribution bar. This design eliminates shrink porosity, producing dense, porous free castings. Manufactured of a high strength, extra rigid wax formula, SuperSpru™ Runner Bars have no memory, preventing bridges from warping and bending during investing.
