Designed for a clean installation, the RAM-B-231Z-2U base accommodates most common rail and bar sizes on UTVs. With the strap clamp safely concealed 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, allowing you to modify the mount for another mounting location. The base also includes black cover caps to be placed over the exposed ends of the U-bolt.
