The RAM Marine Grade Aluminum Yoke Mount consists of the 1" dia. ball and socket system with RAM Universal 2.5" diameter Plate. This mount is designed to be a universal mounting solution for both RAM and non-RAM designed products. The hole pattern found on the 2.5" Plate will connect to a large variety of third party cradles and mounts.
The RAM-B-121B RAM Mount Powder Coated Marine Grade Aluminum Yoke Clamp Mount Base fits a rail diameter from 5/8 inch to a maximum of 1 1/4 inches. The 1 inch rubber ball is at a right angle to the plane of the mount so when connected to a rail, the ball sits parallel to the rail. To mount the base, simply place the yoke clamps around the rail and then screw the large knob at the end of the threaded rod. The hand tightened clamp makes this the perfect mounting system for rental planes and unusual shaped motorbike rails.
NOTE: The rail does not need to be perfectly round to mount this base.
The Powder Coated Marine Grade Aluminum SHORT Double Socket Arm is 1.75" long when measured between socket centers.
END PLATE DESIGN:
The RAM-B-202 RAM Mount Marine Grade Aluminum Universal Plate has a 1.0" diameter Rubber Ball connected at right angles to a 2.5 inch diameter round plate. The plate has pre-drilled holes in the base plate, including the universal AMPS hole pattern. For a layout of the hole spacing and 1.0 inch rubber ball location, take a closer look with the RAM-B-202 Design Drawings (pdf file).
Note: This base plate will attach to any of the RAM plastic HOL holders, but generally the RAM-B-238 Diamond Plate is used.
