SlotCones offer multiple uses never before possible with cones! One side has a unique vertical slot that locks in all diameter hoops. The other side has 5 horizontal slots that hold crossbars from 3” to 18” high. SlotCones are a little heavier and twice as strong as typical plastic cones. Optional slip-on weighted rubber base makes them even more stable than heavy-duty traffic cones. Choose thinner “Roll-Out” Crossbars, which come out of the slots when struck, or slightly larger “Lock-In” Crossbars fit snuggly. Available in COLORZ set of 6, fluorescent orange, yellow. SlotCone Obstacle Kit includes 6 Cones, 3 hoops & 3 “lock-in” 40” L crossbars. The only cones you’ll ever need!
