Note on grille sizes:
Grille sizes stated reflect the size of hole cut into the surface. The grille has a flange which is 1/2” all round. So a 10 x 4 grille needs a hole 10” x 4” and the visible part of the grille will need a surface area of 11” x 5”. Grille sizes are refered to in inches as they are American products and this is their format.
