Description
Individual 70mm diameter round soffit ventilators are designed for use with traditional soffit boards to provide primary sourced roof ventilation. The plastic vents push fit into predrilled holes regularly spaced in the soffit board. Ventilation air flow feeds through evenly spaced holes to a regulation 4mm standard that are large enough not to be blocked with debris but small enough to prevent ingress of large nest building insects/vermin.
