3 lane balancer or 3 to 3 belt balancer?

Choose this when each of three belts carries uneven lanes. When the issue is uneven belts rather than uneven lanes, the 3 to 3 belt balancer is the right tool, and it is smaller. This lane balancer uses express parts and is listed for red, blue and turbo undergrounds.
