This non-slip base pole pad from Vico makes installing a boat cover quick and easy. With the ability to swivel and hold the pole in place, you no longer have to climb in and out of the boat as you install the cover. The thermoplastic rubber gives the pad a firm grip and its large base protects flooring from damage caused by standard crutch tips and helps disperse the pole's weight. Unique 4 piece design with locking wing nut. Guaranteed to fit on Vico Marine's support poles only.
