Working Mechanism

The surface features a matte silver-white anodized finish. When the door closes, the frame squeezes the adjusting copper head screw, which drives the sealing strip downward to close the gap. As soon as the door opens slightly, the seal lifts automatically, ensuring no friction or wear on the floor.

Cutting Instructions: The sealing strip can be trimmed by up to 15cm if needed. Always cut the side without the copper head.

If plates are in the groove: Strip should be 8mm shorter than door width.
If plates are not in the groove: Strip should be 5mm shorter than door width.
