These MSI plastic-framed grilles offer the HVAC industry a unique and functional product. The grille is constructed standard with a smooth white UV ABS vacuum-formed frame and white baked-on mill-painted aluminum blades. The blades are installed as fixed (PG) or adjustable (PGA) into an ABS plastic track.
Installed into the sides of the grille are stainless steel spring catches. They secure the blade/track assembly inside the grille frame but their primary purpose is more functional. They hold the grille into what we call a mounting frame. This mounting frame (MF) is constructed of four injection molded corners and four pieces of extruded sides glued together. It is mounted from the finished side of the wall and then the grille is snapped into it. Grille removal is just as easy.
These grilles are special order and may be drop shipped direct from the factory.
