The one-piece solid aluminum construction is lightweight and strong. The
free-rolling ball bearing cars let you hoist and reef the main quickly
on all points of sail. Cars are easily removed from the track by freeing
the screwpin endstop and sliding them off. Stainless steel wire guides
keep the balls captive when the car is off the track.
