The 7" Throttle Box is another great product of Columbia's that offers years of great performance. All billet construction with a threaded stainless steel ball, this Corner Box looks and operates seamlessly. All Columbia's Corner Boxes now come standard with automatic capabilities, making pushing the box at least 50% easier than standard boxes. The new springs have adjustable tensions and greatly reduce the occurrence of air pockets while running. The Throttle Box allows the corners to be quickly coated with your choice of angle head or applicator head.

• 7" Throttle Box
• Columbia One Extendable Handle
