These spinnaker cars are designed for the yachtsman who wants a safe, effective means of pole attachment for less than the price of the pin type car. The heavy duty FC-125 spinnaker car allows both vertical and horizontal movement while eliminating undesirable twisting motion of the spinnaker pole. The car slide is high strength, hard anodized aluminum alloy. The pole acceptance jaw is stainless steel. Fits all standard 1-1/4" x 3/16" flat stainless or aluminum T-track. Recommended for "UTR" and "UXP" type spinnaker pole ends.
