- Materials and installation: Made of durable materials. No tools, no drilling, no dirt. Easy to install and start using. - Super strong magnets: Reinforced magnet strips provide strong adhesion. The number of magnets required depends on window size; larger windows may need more magnets to ensure a secure hold along the frame. - Window net magnet: Small components designed for windows with a narrow gap between the window frame and the fan. The window net can be opened and closed easily. - Easy installation: Use the included instructions to install modules on the window frame and attach the corresponding modules to the mesh. They stick in place quickly without drilling or screwing. Use scenarios: - Kitchen or living room windows with a window fan, to allow airflow while keeping debris and insects out. - Bedroom windows for convenient nightly ventilation, with easy opening and closing of the net. - Small or narrow windows in offices, RVs, or workshops where space between frame and fan is limited, providing secure and fast attachment.
