High Quality RECTANGULAR Vents are of Galvanized steel
construction. The 2" thick louver mounts flush on the wall,
with Flange on the FRONT and extends into the wall.
These vents have a 24-Gauge frame with mitered corners
to complete an unfinished hole in the wall. WOOD TRIM
is then applied to cover up the flange and finish off the vent.
PLYCO Vents are designed for maximum air flow and come
with a 1/4" mesh screen on the back (1/8" Optional).
Return angle on the 3" louver blade prevents leakage.
