DAUVENT DUST GUARD: The dauvent dust guard protects our awnings from rain, snow, frost, sun and other weather damage. It can also prevent damage from birds, leaves and dust, so the awning can last longer. MATERIAL: The windbreak dust cover is made from 300D Oxford fabric, which is waterproof, dustproof, wear-resistant and durable, and there are no problems when placed outside in the wind and sun. SIZE: 4 m. Please confirm the size of the windscreen to be protected before purchasing to ensure that the size of the protective cover is appropriate. SIMPLE INSTALLATION: The bottom mouth of the windscreen dust cover has a cable tie design. Put the dust cover on when in use, then fasten the cable ties, so that the dust cover fits over the windscreen without fear of being blown off. WIDE RANGE OF USES: Can be used in courtyards, balconies, gardens and other locations, and can be used in all seasons. The protective cover is perfect for standard manual awnings that do not already have the existing protection of an aluminium cassette.
