How to use

Ensure the glass or acrylic surface is clean and free of dust, algae or silicone residues. Press the suction cup firmly against the flat surface, apply steady pressure to expel air from the cup, and engage the handle to check that suction is achieved. Route tubing or place the accessory against the handle or center of the cup as required. To remove, lift the handle to break the seal and peel the cup away gently. Replace any cup that shows cracks, deformations or reduced flexibility to maintain reliable holding power.

Usage recommendations

For best performance, regularly inspect the suction cups and clean both the cup lip and glass. Avoid mounting heavy objects or placing cups on uneven, scratched or porous surfaces. When used in saltwater aquariums, rinse periodically to remove salt deposits and maintain suction.
