A front grille is required for all 4-way ceiling cassette units. This grille will fit LCN series units. The LCN ceiling cassettes are used with the LG Single and Multi-Zone Systems.
The PT-QCHW0 is a true 2x2 decorative grille and covers the inner working of the ceiling cassette unit as well as the ceiling cut-out. Air flow is directed through the grille cover.
