The RAM-B-189B-201-ALA1-KRU consists of a double 3.3" twist lock suction cup base that is connected to the diamond base with 1" rubber ball. The suction cup is designed to have an extra strong hold on any smooth non-porous surface, but for best result, mount the suction cup on a glass or non-porous plastic surface. The ball on this base connects to the standard length double socket arm with retention knob. A single spring inside the arm opens the end sockets, allowing you to pivot the ball and socket connection. The knob extension allows for easy adjustment of the mount and prevents over loosening of the knob. This socket technology allows for almost infinite adjustment and perfect viewing angles.

Carter C. ★★★★★

Went through a car wash with my phone mounted on the windshield using this base, and it didn't budge an inch. The dual 3.3" suction cups with the twist-lock really do hold tight, and the 1" rubber ball in the socket arm lets me angle it exactly where I need it.

Claire N. ★★★★★

The twist-lock mechanism on these suction cups grips the windshield so firmly I have zero concerns about my device coming loose, even on bumpy roads. The 1" rubber ball and socket arm allow me to angle the mount perfectly for navigation. Installation took under a minute after cleaning the glass.

Owen ★★★★★

I was worried my tablet would wobble on the dashboard, but the dual twist-lock suction cups grab the windshield like a vice and hold solid even over rough pavement. The retention knob gives me confidence it won't budge, and the 1-inch rubber ball at the diamond base lets me tilt the screen just righ
