Ashworth Bros.’ Rack & Roll crates provide an efficient solution for storing and installing ExactaStack self-stacking spiral replacement belts. The crate system is designed for quick roll-out, roll-in belt replacements. ExactaStack self-stacking spiral belts are delivered spooled onto Rack & Roll crates, and each crate has a footprint and height of less than 4 ft, making the belt easy to stack, store and maneuver. Installation of a self-stacking belt with the crate system is simplified by rolling out the new belt directly from the crate to the infeed of the stacker. The old belt is conveniently rolled into an empty crate from the outfeed.
