Magnetic door holders are devices designed to keep doors open by using magnets. They typically consist of a magnet attached to the door and a metal plate or another magnet fixed to the wall or floor. When the door is pushed open, the magnet holds it in place, preventing it from swinging shut due to drafts or movement. These holders are commonly used in various settings, including homes, offices, and commercial spaces. They provide a convenient way to maintain airflow and accessibility while ensuring safety. Magnetic door holders are easy to install and can be found in different styles to match any decor.
