Skateboard Plus Kit For Doorway Dolly

• The Skateboard features a Split Carriage Design which ensures friction-free & smooth turning on Curved Tracks. Two Carriages have 4 wheels on each instead of the traditional 8 wheels per carriage design which helps all 32 wheels to maintain contact with the tracks even during turns.
  Custom Made 100% sealed ball bearings provide extremely smooth dolly movement. These ball bearings have been designed to withstand heavy loads and function incredibly well. The wheel carriages are articulating, adjust quickly and easily to variations in Track Curvature for a very precise & smooth dolly movement.
