Quick answer
Choose the RAM Multi-Pad Mount with Twist-Lock Suction Cup Base for temporary mounting on glass or smooth plastic, or the Diamond Base version for a permanent, bolted installation on flat surfaces.
Mounting surface determines your choice
The main difference between these two RAM Multi-Pad mounts is the base. The suction cup version relies on a vacuum seal to glass or non-porous plastic, while the diamond base uses pre-drilled holes for a screw-down installation. Your vehicle's interior surface will dictate which option works best.
If you frequently swap vehicles or need to remove the mount, the suction cup base offers flexibility. For a permanent setup in a single vehicle, the diamond base provides a more stable, theft-resistant solution.
Adjustability and reach
Both mounts use RAM's 1" diameter patented rubber ball and socket system with a double socket arm, giving you nearly unlimited adjustment. The suction cup version includes a 3.3" diameter twist-lock base that secures firmly to smooth surfaces. The diamond base version mounts directly to a flat surface with screws, offering a lower profile but requiring a permanent installation location.
Trade-offs at a glance
- Suction cup base: Twist-lock suction cup grips glass and non-porous plastic. Easy to reposition or remove. Best for temporary or multi-vehicle use. Check that your mounting surface is smooth and non-porous for a reliable hold.
- Diamond base: Permanent screw-down installation on flat surfaces. Lower profile and more secure against theft or vibration. Requires drilling or pre-existing holes. Confirm the mounting location is flat and accessible for drilling before purchasing.
- Adjustability: Both mounts feature a double socket arm with RAM 1" ball system for near-infinite positioning of the notepad.
