Beam track is available from size 0 to 3 and is used when spanning cockpits and across companion way hatches.
Drilled track is commonly used and particularly useful where through deck fixing is not possible, such as in double skinned boats, where fixing bolts are trapped into a plate in the deck. Available from size 0 to 3.
Sliding bolt track is available in sizes 1 & 2 and has a smooth clean profile with no visible fixings and the ability to retro-fit new track to the deck using original bolt holes there is no need to worry about old track pattern holes matching up with a new track. The track is designed to permit a washer to fit on each bolt between the track and deck to ensure a secure seal.
