RAM Mounts Twist-Lock Low Profile Suction Cup Double Ball Mount Black RAP-B-166-2U

The RAM Mounts Twist-Lock Low Profile Suction Cup Double Ball Mount (RAP-B-166-2U) is a compact mounting solution designed for secure attachment to smooth, non-porous surfaces such as glass and hard plastics. The assembly includes a 2.75" twist-lock suction cup base, a double socket arm with adjustment points at both ends, and a diamond base adapter. The system uses RAM's 1" diameter rubber ball-and-socket connection to provide a wide range of positioning and precise viewing angle adjustment while keeping a low profile that minimizes obstruction.

Advantages

The suction cup twist-lock base produces a strong hold on windows, windshields and RAM adhesive disks without permanent installation. The double socket arm offers near-infinite adjustability by combining two ball-and-socket joints, enabling stable, repeatable positioning. The diamond base adapter features a standard hole pattern that is compatible with most RAM cradles and device holders. The entire mount is finished in black for a discreet appearance and corrosion-resistant performance in typical vehicle environments.

Suitable for

• Mounting smartphones or tablets on vehicle windshields or dashboards (on smooth surfaces)
• Temporary mounting of navigation devices or GPS units
• Attaching device cradles to glass or non-porous plastic surfaces in offices or work vehicles
• Use with RAM adhesive disks when mounting to textured or painted surfaces

Key specifications

• Suction cup diameter: 2.75 inches
• Connection system: RAM 1 inch diameter rubber ball-and-socket
• Arm type: double socket arm with adjustment at both ends
• Base adapter: diamond base with multi-hole pattern for cradle attachment
• Colour: Black

How to use

Clean the mounting surface thoroughly to remove dust, oil and moisture, then press the suction cup firmly onto the smooth surface. Engage the twist-lock mechanism to create a secure vacuum seal. Attach the diamond base adapter to your RAM cradle or device holder using the appropriate fasteners through the adapter’s hole pattern. Adjust the double socket arm and ball-and-socket joints to set the desired viewing angle, then tighten the socket clamps to lock the position.

Recommendations

For best adhesion, avoid mounting to porous, textured or heavily curved surfaces; use a RAM adhesive disk when installing on painted or textured dashboards. Periodically check the suction cup and re-torque the socket clamps after initial installation and before each use to ensure stability. Do not expose the suction cup to extreme temperatures or prolonged direct sunlight when possible, as this can reduce suction performance over time.
