The GraviSky bridges are like small levels for your marble run, only in a straight line. Practical for Skytrax, because you can use classic GraviTrax elements directly next to Skytrax elements at the same height.
Fully compatible with Skytrax: The bridges also offer drops for the balls, so the GraviSky bridges can also be easily installed in a Skytrax construction. The GraviSky bridges can of course be used on Skytrax stones and on normal height stones.
Two different lengths are available: 3 or 4 fields.
