RAM Mounts RAM-B-101U-A Short Arm with 2 x 2.5" Round Bases

The RAM Mounts RAM-B-101U-A is a compact, heavy-duty mounting system featuring a B-Size 1″ ball system, short double socket arm and two 2.5″ round bases.

The short arm keeps your mounted device close to the mounting surface, making it ideal where a compact, low-profile setup is required. The RAM ball-and-socket design provides adjustment at both ends of the arm, allowing you to position your device at the required viewing or operating angle before locking it securely into place.

The rubber ball system also helps dampen shock and vibration, making the RAM-B-101U-A well suited to vehicles, boats, machinery and other demanding applications.

Both 2.5″ round bases feature the universal AMPS hole pattern, providing compatibility with a wide range of RAM Mounts device holders, cradles and mounting accessories.
