26 mm Switch T-Track Battcar - Double Storage Track - 28-1/2" Long

On large yachts, Harken's Switch T-Track Battcar Systems cut the Battcar stack height of a lowered mainsail in half by automatically splitting cars onto two side-by-side tracks just above the boom. This makes it much easier for crew to put on sail covers and to connect and disconnect halyards.
The unique switch plate has no moving parts, ensuring exceptionally reliable functioning. Small protrusions on the side of each car determine which track the car drops onto. The cars are attached to the sail with the protrusions on alternating sides - so they alternate tracks as they drop.

Note that 22 mm Switch T-Track is the only size where the two storage tracks come as their own piece of dual track (with a separate, add-on switch section).
In 18 mm Switch T-Track, the switch and double storage track are all a single integral piece. In 32 mm and 50 mm sizes the "double" storage tracks are created from separate pieces of track mounted side-by-side.
