RAM Mounts Twist-Lock Suction Cup Base with Ball (RAM-B-224-1U) is RAM's go-to base for windshields: a Ø 84 mm (3.3") Twist-Lock suction cup combined with an aluminium diamond base carrying a 1" B-size ball. Flip the lever to lock it firmly onto glass or other smooth, non-porous surfaces in cars, vans, trucks, boats or on a window – and remove it again without tools or marks. Add a B-size double socket arm and a device holder to complete the mount.
