Description
The RAP-B-217-365-224-1U is a triple Twist-Lock suction cup base with a dual B-size ball adapter—the distinctive feature of this product is that you can mount two holders or devices at the same time from a single base. Ideal for side-by-sides, overland vehicles, golf carts, and 4×4 applications where both navigation and communication equipment need to be within easy reach.
Three Twist-Lock suction cups for maximum grip
The three suction cups each have a diameter of 3.3″ (8.38 cm) and lock into place using the RAM Twist-Lock mechanism. The total width of the triple base is 7.95″ (20.19 cm). Three points distribute the load over a larger surface area, ensuring the base remains securely in place even during vibrations and shocks on unpaved terrain. Suitable for glass and non-porous plastic surfaces.
Double B-size bullet adapter: two devices, one base
The round base plate (diameter 2.5″ / 6.35 cm) features a dual B-mount 1″ ball adapter. You can attach two separate B-mount ball arms with mounts to this—each to its own ball. The maximum total load for both mounts combined is 1.85 kg (4 lbs). For example, you can combine a phone mount with a GPS mount, an action camera adapter, or a RAM X-Grip tablet mount.
Compatible with all B-size RAM Mounts components
Both mounts are compatible with all B-size double-mount arms, phone holders, tablet holders, GPS adapters, and other B-size RAM Mounts accessories. Adjust the arm length using the RAM Double Socket Arm Medium—the short or long version—to achieve the desired position and viewing angle.
Material: high-strength composite. RAM Mounts offers a lifetime warranty on this product. The rubber on the suction cups is a wear-and-tear part and is not covered by the warranty.
