With a 6,000lb breaking strength on the rails and a 1,500lb working load for each O-ring, it provides massive peace of mind when transporting ATVs or motorcycles. It is a rugged, weather-resistant solution that saves a significant amount of money compared to buying the rails and anchors separately.

Ever wondered how to maintain a perfectly straight line when your workpiece is longer than your track saw?
