Category: VBF Series (Bellows Flat Vacuum Suction Cups)
Features & Strengths :
- Cardboards
- Veneer Sheets
- Plastic Sheets
- Wooden Products
The VBF series are excellent with slightly rounded surfaces and flat surfaces. The cleats on the suction cup allows for an enhanced gripping force on horizontal movements. The wider surface of the lip allows for good lifting force that can be achieved in vertical plane.
