Product description Material: stainless steel Color: white, silver Whether it's magnetic: yes Quantity: 4 pieces Package content: 4 x magnetic door stoppers, 4 x adhesive tape, 8 x fixing dowels, 16 x screws. 1. Long, raised plate: Stop worrying about the gap between the doorstop and the door. Although the doors are higher than this doorstop, you can also work through the long stop plate. This magnetic dome door fits doors with a gap of 3mm to 30mm. 2. Rust-free and durable: The magnetic door stopper is made of high-quality, brushed stainless steel, robust and rust-resistant, so that work in damp environments is also guaranteed. The thickened bottom can significantly extend the life of the door. 3. Easy to install: Two ways to install the doorstop on the floor. 1. No drilling required. 3M VHB double-sided tape ensures that the doorstop is attached to the floor. 2. You can choose the drilling template, the strongest hole design allows permanent installation on the floor with screws is more durable and stable (we recommend this installation method). 4. Magnetic force and shock absorber: The magnetic door stop is strong enough to hold the door in the wind and grab it to prevent the door from slamming by the wind. The semi-circular rubber bumper design can reduce the collision and better protect your door and wall. 5. What you get: 4 x magnetic door stoppers, 4 x tape, 8 x mounting plugs, 16 x screws.
