This Gravity Flap Wall Outlet is suitable for use with round vents to provide ventilation to your home. Ventilation is an essential element in all buildings, as proper airflow reduces levels of moisture to prevent mould and rot which can be detrimental to the structural integrity of wood and drywall, as well as to health.
Good ventilation also helps to remove unwanted smells, such as from cooking or pets. This Gravity Flap Wall Outlet is Terracotta and constructed from PVC for strength and durability.
