The RAM Mount 1.5" Ball Short Arm with 2.5" Round Base (RAM-103U-B) includes a short single socket arm with one open 1.5" C size ball socket end, and a 2.5" round base with a 1.5" rubber ball and the universal AMPS hole pattern. The arm connects to any RAM cradle or mount component with a 1.5" C size ball. Powder coated marine grade aluminum.

What It Does on the Water

The RAM-103U-B gives you a flat surface mount point using the 2.5" AMPS round base, and a short single socket arm to connect to a 1.5" ball cradle or device holder. The single open socket end accepts any compatible 1.5" C size ball, and the short arm keeps the overall profile low. The AMPS hole pattern on the base connects to a wide range of RAM and third-party cradles. For a double socket arm version, see the RAM-103U.
