The Trim and Sleeve Kit is composed of a Finish Flange and a Sleeve lining that fits into the rough opening to provide a clean finished look on the interior wall. Trim flanges are available for use with standard masonry flood vents (1540-533) as well as our stacker and multi-frame models in stainless steel.  Trim Flanges are available for Wood Wall Models (4” depth 1540-573 and 9” depth 1540-573-9) in standard, powder-coated white.

The stainless steel sleeve lining that comes with the 1540-531-15 can span to cover a wall depth between 10" and 15.5"
