No ordinary single jump, this jump is made with 3/4″ thick walled, impact resistant FURNITURE GRADE PVC & FITTINGS* (not the usual plumbers grade PVC seen elsewhere). The furniture grade PVC has a glossy “bright white” finish, this is one of the sturdier jumps you can find. This single jump has a ground-level base bar that makes for a quality jump that will not easily tip over. This DOUBLE BAR single jump comes with 4 snap on AKC regulation jump cups so that you can adjust your jumps to any height that you choose quickly and easily. Both bars displace easily if nicked by your dog during a jump making it safe for you pet. The jump is 3′ foot tall by 4′ wide. The Double Bar Single Jump assembles quickly and easily, is very portable and breaks down to stow in very little space.
