Includes RAM-B-202 base with 2.5" diameter platform. Compatible with all 1" RAM receptacles. Requires RAP-300-1U.The Marine Grade Aluminum Universal Plate has a 1.0'' diameter Rubber Ball connected at right angles to a 2.5'' diameter Plate. The plate has pre-drilled holes in the base plate, including the universal AMPS hole pattern. If required, the different hole patterns allow you to connect this plate to almost any type of existing hole pattern.
NOTE: This base plate will attach to any of the RAM plastic HOL cradles, but generally the RAM-B-238 Diamond Plate is used as it provides a cleaner-looking mount to the HOL cradles.
Mounting hardware is NOT included with the purchase of the RAM-B-202. A semi-permanent solution for mounting this base is by using the RAM double sided adhesive disk (RAM-202PSA, sold separately). The disk will hold the RAM-B-202 base is many different locations without screws.
