B-Size Ball Cup Holder Base

The Keyence cup holder base provides a 1-inch metal ball head built to the B-size standard for RAM double-socket arms. It expands to grip cup holders measuring 3 to 4 inches in diameter, covering most sedans, trucks, SUVs and RVs. The package contains only the base; the arm and phone cradle must be supplied separately. Builders who need a different ball size or a non-expandable mount cannot use this base.

Sustained Vibration Stability

Anti-slip silicone pads and a twist-locking mechanism keep the base seated firmly during extended drives on rough pavement or off-road trails. The aluminium-alloy ball and ABS body resist fatigue and cracking where lighter plastic parts would deform over time. No tools are required, so the clamping force can be rechecked and retightened at any stop. Users who expect a permanent bolted installation will not find that option here.

RAM B-Size Interface Limits

The 1-inch ball mates exclusively with B-size double-socket arms; it will not engage A-size or C-size sockets. Cup holders outside the 3-to-4-inch range cannot be accommodated by the expandable base. Because the ball is fixed to the base, the assembly cannot be adapted to other mounting systems without replacing the entire unit. Buyers needing a smaller ball diameter or a wider cup-holder spread must select a different base.

Questions about this item

Does the expandable base grip a 3.5-inch cup holder tightly enough that it will not rattle on the highway?

The base expands from 3 to 4 inches and uses anti-slip silicone pads with a twist-locking mechanism to hold firmly without wobble.

What separate parts do I need to complete the mount since the package only includes the cup holder base?

You must supply a RAM B-size double socket arm and a compatible phone holder; neither is included.

Will the 1-inch metal ball on this base connect directly to my existing RAM B-size arm without an adapter?

Yes, the 1-inch ball is the standard B-size interface and mates directly with any RAM B-size double socket arm.
