Forespar® offers anodized aluminum T-track in one standard size. Track comes pre-drilled with alternating pin-stop and mounting holes. The base of the track is gently curved to better accommodate mast surfaces. We offer it in 5′ and 10′ lengths only. The recommended fasteners are 5/16″ X 3/4″ Stainless Steel Flathead Machine Screws.
Use Lanocote paste, #770001, on the screw threads to prevent corrosion between the screws and the mast.
