This replacement upright guide on is manufactured out of 1 ½” square hot dipped galvanized steel tubing, measuring 41” tall with the leg measuring 31” long.  The length of the leg allows for easy adjustments to fit your boat properly.  This guide pole is designed to have a 2” PVC pole slide over top of it and rest on the tab already installed on the guide for the correct placement. The PVC sleeves are available and sold separately.  The guides will typically attach into a cross member or by using u-bolts to attach to an I-beam frame.
