Submerged guides don't work! These innovative Floating Guide-Ons from Tie Down are designed to be functional and make your pontoon trailer more visible in deeper water. Pontoon trailer guides are made to "float" in water, extending up an extra 12" in height. The added visibility and height help you center your pontoons on the trailer for easier loading. Bright orange end caps make the Tie Down floating guide-ons even easier to see. 2" dia. x 20"L slotted PVC pipe guides slides up and down easily on the 1-1/2" square, 16-gauge galvanized steel posts. Mounts to trailer cross members up to 2"H x 2" - 4"W. Floating guide-ons include mounting hardware. Sold in pairs.
