The RAM-B-201-C-KRU, long double socket arm, has a socket at both ends that accommodate 1" ball bases. A single spring inside the arm opens the end sockets, allowing you to pivot the ball and socket connection. This socket technology allows for almost infinite adjustment and perfect viewing angles. The knob has a locking Acorn nut that prevents the mount from being removed from the socket. This Feature allows for a secure mount while giving the ability to adjust your device without the ability to remove the device.

Amelia C. ★★★★★ Oct 23, 2026

I needed a longer reach for my setup, and this double socket arm gives me exactly the right positioning flexibility with its single spring retention knob. The ball sockets hold tight without any wobble, even on bumpy roads.

Mia ★★★★★ Oct 22, 2026

The sockets grip the ball mounts firmly with no wobble, even on bumpy roads. That single spring inside makes adjusting the angle effortless while still holding my tablet securely.

The spring-loaded retention knob makes swapping out my GPS mount so much quicker than with the old thumb screw versions. Installed this on my motorcycle handlebars and it hasn't budged an inch after a few hundred miles of bumpy roads.
