Bellows Suction Cups are excellent for Concave and Convex surfaces and elimintates the need for spring suspensions in many cases
2.5 Bellows Vacuum Suction Cups attach gently and easily with minimum pressure. They are excellent for concave and convex shapes as well as on slanted surfaces. Their design can replace mechanical springs, ball swivels and height compensators, allowing for less complicated and more economical installations. Keeping vacuum level a bit lower extends the life of the suction cups.
