After more than 70,000 tests, the doorstop will provide a longer service life than other doorstops on the market. Provide 1/2/4/6 pieces of door stop to meet your needs If you are not sure whether our door stop is suitable for your needs, you can choose 1 packaging type first. Keep your door open-have you encountered this trouble If you want to leave the door open, the breeze blows, and the door slams shut, naughty pets and children will close the door roughly, causing damage to the door and the wall. Now, magnetic door stops are a good way to keep regular inner/outer doors open. Ideal for windy areas to maintain air circulation in the house without inevitably closing the door violently. Prevent damage-The magnetic door stop prevents your door from slamming through the integrated soft card door technology. It has a soft card door function that can gently and silently stop and hold any door. The lock is equipped with a beautiful spring buffer, which can absorb the excessive force of closing the door, provide better protection for the wall, and give you peace of mind. The tug will release the door to maintain privacy. No need to drill, 2 installation methods-use 3M stickers without drilling, no holes, or permanent installation with screws. If you are not sure whether our products are suitable, you can choose 1 packaging type first. Personally, I would recommend installing with screws, which will be more durable. Sometimes 3M may damage the surface due to the daily work of the magnet 3M mats should be used on smooth/flat/dry surfaces, not on dry walls/cement/latex painted walls and any uneven surfaces.
