A front grille is required for all 4-way ceiling cassette units. This grille will fit LMCN**HV and LCN**HV4 series of ceiling cassettes. These ceiling cassettes are used with the LG Single and Multi-Zone Systems.
The PTDCQ is a 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.
Actual dimensions of the PTDCQ grille cover are 35-3/4" x 35-3/4" x 12-1/8".
