The RAP-B-347 High Strength Plastic Composite Universal Plate has a 1.0 inch diameter Rubber Ball connected at right angles to a Rectangular Plate. The plate has pre-cast holes in each corner making the universal AMPS hole pattern. If required, the different hole pattern allows 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.
