Double-hand Suction Cup with Ratchet (Doppelhandbecher mit Ratsche) Key benefits Precise pulling and alignment: ratchet mechanism provides controlled force to draw two flat parts or seams together during assembly. Faster, safer handling: frees hands for positioning while maintaining a steady hold on flat, non-porous surfaces. Versatile use: works on a wide range of smooth materials, reducing the need for clamps in many installation and repair tasks. What it does Designed for pulling and aligning parts during assembly and for bringing two flat surfaces or seams together. Secure suction combined with a ratcheting handle allows gradual, controlled tightening. Important attributes Function: Pulling, aligning, and holding flat parts and seams during assembly. Compatibility: For flat, non-porous surfaces such as marble, granite, mirror bases, glass, and plastic. Not intended for porous or highly textured surfaces. Total length: 450 mm Rubber thickness: 7 mm Suction cup diameter: 15 mm Suction capacity: 50 kg / 110.2 lb / 110.2 oz Practical use scenarios Stone countertop installation: Use to align and bring together marble or granite slabs for seam bonding before adhesive sets. Mirror and glass handling: Hold and draw mirror bases or glass panes into precise position while fixing or sealing. Plastic panel assembly: Pull and align flat plastic sheets during bonding or trim operations where clamps are impractical. Why customers need it Provides a simple, controlled method to pull and align flat parts that would otherwise require bulky clamps or awkward manual force. Reduces repositioning time and improves fit accuracy for seams and joins on smooth, non-porous materials. Notes for use Ensure surfaces are clean, dry, and non-porous for reliable suction. Do not exceed the stated suction capacity. Inspect rubber cup for damage before use to maintain performance and safety.
