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. An optional black haircel ABS with black baked-on mill-painted blades is available (add the code letters BK to the end of any of the product codes).
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 injectionmolded 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.
