Cast Aluminum Jump Cup Strips and PVC Bars (for do-it-yourself builders) One of the most frustrating aspects of trying to build your own agility jumps is what to use for cups to hold the bars, and how to attach the cups to an upright. We now have two sets of cast aluminum strips with cups properly positioned for agility single jumps and the previously difficult-to-make agility triple jumps. The strips have a curve molded in the back, allowing you to attach them to either round pipe or flat uprights. Simply screw the aluminum strips onto your jump uprights at the proper height and the cups are all correctly positioned. We also offer 4' or 5' PVC bars for use on your jumps, striped with color tape. Note: if ordering several sets of jump cup strips and/or bars, additional shipping charges apply.
