The Carbiepoles™ Oval Mounting Base allows you to permanently mount your 53mm Carbiepoles to a solid surface. This mounting base is primarily used for awnings and shade sails to your deck or patio, though it can also be used on boats. The mounting base is made from stainless steel and requires additional hardware that is not included. Each mounting base requires 8 1/4"-20 machine screws, #14 tapping screws or #8 metric screws. Pan head screws are recommended.
