Gravitrax PRO Extension Helix
Cross your marble run down and over with the twisted flair of the “GraviTrax PRO Helix”.
Criss cross, under and over! With the Helix you can join up to six different tracks. When a marble enters the Helix it will move down to a lower level without changing its direction. Up to six marbles can pass through this Action-Stone at the same time! Combined with a Starter-Set, exciting tracks can be built without the marbles obstructing each other on their way to the finish. How many marbles can cross in your tracks?
