Designed to be used as a runner bar during the fabrication process for round-house and long-span bridges, these low-carbon, clear-acrylic sprue bars prevent bridgework distortion during investing and to burn-out cleanly without residue. Once the sprue bars are warmed over a burner, they can be bent to the desired shape to fit the arch when cooled.
