In cloudy days, you can leave it open all day, but you must cover the net in time before the rainstorm.
2. The width of the sunshade net can be cut and spliced arbitrarily.

Do not use iron wire or aluminum wire to bind and ligate, so as to avoid mechanical breakage and affect the service life of the sunshade net.
