Door Pinch Guard and Door Slam Stopper 6pk. Use Safety Door Guard Made of Soft Foam to Keep Door Open. Serves As a Door Protector for Kids by Arcleer

Stops doors from closing. I used them around the house when my child was smaller. At work there's a heavy metal door that has to remain slightly ajar for airflow. One of these isn't strong enough for that door, so I duct taped three together and they work great for holding that door open.

En mi caso sólo usamos los protectores (dos en cada puerta) para mantener ligeramente abierta la puerta y también para evitar que se azote. Funciona bastante bien, aunque los protectores se deforman un poco cuando se presionan contra la esquina del marco de la puerta.

We got these so our toddler can’t pinch his fingers in the door they also work great as an anti door slamming device. They also keep the cats from getting stuck in random rooms around the house

Works exactly as it should. They slide on easily and’s stay put. It keep kids/pets from closing doors. Great price for the set.

One used by itself does not keep our door open. The idea is great but we had to put at least 3 on our door to keep it from shutting.
