This Seaview single marine instrument pod for sailboats has a useable face of 4.63" x 4.63". This Sail Pod comes with one high polished stainless steel clamp. The stainless steel clamps come with three different rubber bushings so that these universally clamp onto 1", 1.125" and 1.25" rails. Security screws are used to hold each Seaview Sail Pod together along with a water tight gasket to prevent water from entering inside the pod. Note, the S.S. clamp will require 3" of straight rail (no radius) to mount securely.
