Super Knuckle 3" Suction Cup


The Kupo Super Knuckle System is an innovative modular system that features a shell that accepts two ball joints mounted to interchangeable accessories on either side. The shell has a single knob in the center to tighten both ball joints simultaneously. The Super Knuckle Suction Cup Adapter allows you to mount the system to hard, flat non-pourous surfaces such as ceramic tile, glass and stone without damaging the surface. It consists of a 3" suction cup on one side and a ball joint on the other. The suction cup has a red indicator line on the white pump button. When maximum vacuum is achieved the red line stays hidden.
