Made with J & J Wire Jump Cup Strips - Patent# 6,976,452 We combined our wire jump cup strips and our PVC agility jumps to make these lower-priced, competition jumps. Our competition PVC jumps feature furniture-grade PVC with wire jump-cup strips on each upright. The single jump has a solid connecting base to keep the distance between uprights constant while the double and triple have freestanding uprights. The single jump also features our easy-locking base design, which allows you to move the jump without the bases falling off the uprights, yet the uprights can easily be removed for transport or storage. Our design also allows you to connect two single jumps using the optional connector set. To make a spread jump, simply remove two feet from each jump and replace them with the connectors. The full set of three single jumps includes anylon carrying bag. The panel jump comes with 4' wide PVC panel jump boards.
