This mount allows for two tracks (not included) to be mounted to the wall, side by side. For uninterrupted action, a 10 MM spacing is provided between the 2 tracks to ensure that no car contact is made when racing. Imagine the possibilities as you take your track layouts to new heights, utilizing your room space to the max by combining both floor and wall car racing. Easy to assemble, simply attach the 2 Lane Wall Mount to the wall with the 3M Damage Free Hanging Strips (not included), or use 2 screws (not included) with the pre-drilled mount holes for a more permanent placement.
