Prevent dry rot and mildew from forming on your cover using our boat cover support poles. These light weight poles are designed with a rubber foot on one end and either a metal snap or rubber tip on the other. Each snap in style pole comes with a patch of material with adhesive backing and a metal snap in the center. This will stick to the inside of the cover where the support is needed and the pole would then be able to snap in at this location. The tip end style includes a rubber tip that is designed to insert into a grommet or other location in the boat cover for support and water drainage.
