All our Corner Boxes now come standard with automatic capabilities, making pushing the box 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.
