Excellent for round-house and long span bridges.
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.
Available in 6" and 8" rods.
