How to stop the door:
When you place the \"Door Cube\" in front of the door with a door closer, there is a high amount of friction between the ball, the door surface and the floor. At the same time, the ball, which is pushed and misshapen by the door, will stop the door with rebounding forces as it tries to return to its original shape.
Please Read Before Using:
1. This product is primarily an indoor door stopper.This product temporarily keeps a door from closing; it is not intended to keep a door open permanently.
2. Before use, wash the ball with warm water (below 104°F (40°C) and mild kitchen detergent and dry thoroughly.
3. The friction force of this product may not be effective in all situations, and in the following situations it may have difficulty with stopping (or will not stop):
(1) If there is dust or grease on the ball. (In this case, please wash it thoroughly with water before use).
(2) On floors where it is difficult for frictional force to be effective (i.e. long pile rugs or textured carpets without frictional force, tile floors with patterns or treatments that have poor frictional force, natural wood floors, etc).
(3) If the closing force of the door closer is too strong.
(4) If the gap between the door and the floor is more than 0.8 inches (20 mm).
(5) If strong force is applied to the door by natural or artificial means, etc.
4. Please manage the product properly so that infants and/or pets do not touch it, lick or put it in their mouths.
5. The inner rubber ball has a unique rubber smell, but the smell will decrease over time.The door may not stop in places where it is difficult to generate friction, such as carpet, and solid plywood.
*Please read the precautions carefully before using this product.--
