10/08/2026
The structure is designed to snap into the sliding door/window rail so that the sliding door/window can be closed against it: providing a seal to complete the connection between the two and preventing fresh air from escaping to the outside, the system allows you to continue to open and close the door/window freely, without having to constantly untie the Velcro，while maintaining the beauty and utility of the sliding door/window vents.
