The SmallRig Multi-Functional Suction Cup Support is designed to address three common issues: weak suction, limited adjustability, and devices slipping off easily. It features a wide PU suction cup with a diameter of 74.0mm (2.9in). When pressed onto a surface, the PU material conforms to microscopic gaps, creating a sealed vacuum layer that helps it stay firmly attached even on textured surfaces. It leaves no residue and can be washed for repeated use.

A two-stage silicone locking knob improves both ease of use and stability. A light turn pre-locks the mount in place, while a firmer turn increases pressure for a more secure hold. This design allows you to adjust the suction strength as needed and helps reduce loosening during driving.
