The aluminum alloy window screen frame has a rubber strip. First, pick it out, then you can pull the window screen out.
To install the window screen, grind off one side of the rubber rollers at the bottom of the aluminum alloy window frame. Use the remaining side to press the edge of the window screen into the groove of the window frame, then press the rubber strip in. Use a craft knife to remove any excess window screen. If it's a stainless steel window screen, apply silicone sealant to prevent the loose threads from cutting your hands.
When replacing a new window screen, first secure one side, then slightly tighten the other side, and then secure the other two ends in sequence. Be careful not to overtighten, as this can cause the frame to deform and affect the appearance.
