Spindle Capper Control Boxes come standard with a NEMA 4 (NEMA stands for National Electrical Manufacturer's Association) enclosure.  In general, this means that the electronics in the capper control box are weatherproof and dustproof, for added safety and longer capper life.

The capper control box allows for easy adjustment of speed for both gripper belts and spindles all in one location.  Power controls for belts, spindles and more are also located on the capper control box.  Auxillary machinery, such as conveyors, can also be added to the capper control box to centralize control of multiple packaging machines.
