Quick answer
For maximum hold on glass, choose the RAM Twist-Lock Triple Suction Mount. For a compact setup on smooth dashboards or side windows, the Dual Suction Mount is lighter and easier to position.
Why suction cup count matters for cameras
Camera mounts face vibration and weight that can challenge suction cups. More cups spread the load and add redundancy if one cup loses seal. Fewer cups mean a smaller footprint and easier placement on curved or narrow surfaces.
Both mounts use RAM's Twist-Lock design, which tightens the cup against the surface with a twist rather than a lever. This gives a consistent seal without needing to press down hard.
Surface compatibility and placement
RAM specifies that suction cups work best on smooth, non-porous surfaces like glass or non-porous plastic. Textured dashboards, fabric, or leather will not hold reliably with either mount. The triple base requires a larger flat area, while the dual base fits smaller windows or dash sections.
Trade-offs: Dual vs Triple
- Hold strength: Triple: three cups distribute weight and add redundancy. Dual: two cups still hold well on glass but have less margin if one cup loses seal.
- Footprint and placement: Triple: requires a larger flat area, may not fit on narrow window frames or small dash sections. Dual: compact base fits tighter spots and curves more easily.
- Weight capacity: Dual: rated to hold up to 2 lbs. Triple: no published weight rating, but the triple base is designed for extra strong hold. Weigh your camera and lens combo before choosing. If your camera body plus lens exceeds 2 lbs, the triple mount is the safer choice.
