ABSTRACT:
Apparatus for mounting supply and exhaust air valves or other ventilation elements in ventilation conduits comprising one or several anchor devices which are attached by a base onto the back side of the element. From the base extends a triangular intermediate section. One triangle side borders the base, and a second triangle side borders an outward extending wing with circumferential orientation relative to an opening in which the element is to be fastened. The wing is divided by slots into tongues, and the free ends of the tongues are pointed and bent outward in direction toward the walls of the opening. Different configurations of the anchor devices are shown.
