Screen Door Lock - Set of 2 *Design may vary. Prevents children from opening screen doors. Prevents pets like cats from opening screen doors. Prevents screen doors from opening unexpectedly due to sudden gusts of wind. Easy to install. Please confirm the shape of your home and the installation method before installing correctly. ● Upon arrival, please check the installation method and use appropriately. ● We are not responsible for any accidents after installation, so please install at your own risk. ● Please confirm that installation is possible on the installation area of your home before purchasing. ● I have also installed them, and they work very well. Not only for children and pets, but also for elderly family members' homes. I feel that it can also serve as a light security measure to prevent strangers from suddenly entering a room with a screen door open in the summer. It's difficult to see from the outside. However, I think it is weak against strong force, so it is not perfect, but perhaps it can buy you a little time to escape while the intruder is hesitating. This is just my personal opinion, so please consider it as a reference.
