The Columbia Angle Box now comes standard with automatic capabilities. The Columbia Throttle Box makes pushing the box at least 50% easier than standard boxes, and allows the corners to be quickly coated with your choice of angle head or applicator head.

The new springs have adjustable tensions and greatly reduce the occurrence of air pockets while running. In addition to both springs having adjustable tension, you can run both springs, only one spring, or no springs to get the desired tension you prefer. 


  • Available in 7" and 8" sizes
  • New spring tension allows for 50% easier push, and prevents air from getting trapped in the box
