The RAM® Double Socket Arm (RAM-D-201U-C) serves as the “socket” in the RAM® patented ball-and-socket mounting system. This double socket arm connects to any two D size ball adapters or bases. A spring inside the arm keeps one socket open, making it easy to attach to a ball. With an overall length of 8.44" and socket-to-socket length of 6.88", the arm features an easy-to-adjust knob that provides near-infinite positioning.

Andrew ★★★★★ Oct 23, 2026

The spring-loaded tension knob lets me adjust the arm’s stiffness perfectly, and it hasn’t loosened at all after a month of daily use. This D-size medium fits my setup exactly, no wobble.

Zoe ★★★★★ Oct 22, 2026

The ball socket clicks into place with a satisfyingly solid feel, and the tension is just tight enough to hold my tablet steady on bumpy roads. I was worried the D size medium wouldn't fit my setup, but it pairs perfectly with the standard ball bases I already have.

Installed this on my motorcycle mount and it holds my GPS steady even on rough roads. The ball-and-socket design gives plenty of adjustability without loosening up over time.
