Maurice Franklin Round Plastic Vent

These small round plastic vents are made of high quality UV stabilized wire and cable grade polypropylene. They have a unique polypropylene screen system to keep insects out. They are easy to install. They fit into the hole made by a drill-type hole saw and are held in place by knobs on the side of the vent. No nails or screws are needed. They are used for a wide variety of ventilation, from eave and soffit ventilation to insect cages, display cases, spice racks, electrical and mechanical boxes, cargo crates and more. They have 0.200 si nfa (square inches of net free ventilation area).
