Kupo KS-422 Super Knuckle 3in Suction Cup

Kupo KS-422 Super Knuckle 3in Suction Cup – secure temporary mounts on non-porous surfaces

The Kupo KS-422 Super Knuckle Suction Cup Adapter lets you mount equipment to hard, flat non-porous surfaces without damaging them. It works on surfaces such as ceramic tile, glass and stone. The adapter combines a 3" pumping suction cup on one side with a ball joint on the other for flexible positioning.

What it does

The suction cup creates vacuum pressure to hold the adapter to a smooth surface. You pump the white button and watch the red indicator line on the pump button. When maximum vacuum is achieved, the red line stays hidden. This visual cue helps you confirm secure attachment and alerts you if vacuum starts to drop.

Ideal use cases

Use the KS-422 for temporary mounting of lightweight video cameras. Likewise, it suits a variety of lights and sound recording equipment. Because it mounts without drilling or adhesives, you can attach and remove it without damaging ceramic tile, glass or stone surfaces.

• CNC machining aluminum ball head for the ball joint
• Dia. 26mm for the ball head
• 3" pumping suction cup for attachment to smooth surfaces
