Designed for a clean installation, RAM-B-231Z-2U base accommodates most common tubing sizes on UTV's and ATV's, allowing for the placement of the RAM rubber ball base. Safely concealing a strap clamp in a compact housing, you won't have to worry about exposed sharp edges or unwanted loosening. Included in the kit is a zinc coated metal u-bolt, this allowing you to modify the mount to accommodate mounting location. The base also includes black cover caps to be placed over the exposed ends of the u-bolt.
