The RAM Marine Grade Aluminum Yoke Mount consists of the 1" dia. ball and socket system with RAM Universal Extension 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 Extension Plate will connect to a large variety of third party cradles and mounts.
BASE DESIGN:
 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.
ARM DESIGN:
The Powder Coated Marine Grade Aluminum SHORT Double Socket Arm is 1.75" long when measured between socket centers.
EXTENSION PLATE DESIGN:
 The RAM-B-125B Marine Grade Aluminum Extension Plate with 1 inch Rubber Ball allows you to maneuver your GPS unit, or any connected device, in more positions than the standard mounting plate. Originally designed to position your GPS in front of the yoke on your plane, the extension plate can also be used in many other applications.
The end of the plate is 2.5 inches square with predrilled holes for many different screw hole patterns, including the universal AMPS hole pattern and all RAM made cradles. The plate extends approximately 2.25 inches forward, at a 45 degree angle, from the center of the 1 inch ball and approximately 1.5 inches above the 1 inch ball (to the bottom of the connection section of the plate).
