The RAM Mount Flat Surface Mount Short Arm with Diamond Base (RAM-B-138U-A) is a complete surface-to-surface mounting kit. It includes a 2.5" round base with the universal AMPS hole pattern, a short double socket arm, and a diamond base adapter. The 1" B size rubber ball and socket system has adjustment points at both ends of the arm. Overall height is 3.09". Powder coated marine grade aluminum.

What It Does on the Water

The RAM-B-138U-A gives you a flat surface mount on one end using the 2.5" AMPS round base, and a diamond base adapter on the other end for connecting to RAM cradles and device holders. The short double socket arm keeps the overall height low at 3.09", which works well in tight helm spaces. The 1" B size ball and socket system adjusts to almost any angle and locks down firmly. The patented rubber ball design absorbs shock and vibration to protect your electronics in rough water.
