Twist-Lock Suction Cup 1" Ball (B) Base

RAM® Twist-Lock™ Suction Cup Base — Strong Hold, Zero Commitment

The RAM® Twist-Lock™ suction cup base delivers a surprisingly powerful hold on smooth, nonporous surfaces — no drilling, no tools, no permanent mounting required. Whether you’re setting up on a windshield or another flat surface, this base locks in tight and stays put, even when the road gets rough.

At the core is a 3.3” Twist-Lock™ suction cup paired with a B-size (1”) RAM® rubber ball mounted on a diamond base. Add your favorite RAM® double socket arm and device holder, and you’ve got a fully adjustable mounting solution that’s easy to install, reposition, or remove whenever needed.

Built from high-strength composite and marine-grade aluminum, it’s designed to handle vibration, weather, and everyday abuse — all backed by RAM®’s lifetime warranty.
