EZ Plenum EZLP18X4KD Knocked-Down Fiberglass Linear Plenum Box fits 18"-Inch 2-Slot Diffuser

This is a R6-rated fiberglass "knocked-down" linear plenum box that fits a 18"-inch 2-slot linear diffuser grille. This linear plenum box is shipped "knocked-down", meaning it is prefabricated but requires assembling (tape is NOT included). The standard height of our linear plenum boxes when assembled are about 12"-inches high.

Please make sure to choose the correct manufacturer of your linear diffuser grille and slot thickness so we may provide the plenum box to fit your linear grille manufacturer specifications (if your manufacturer is not listed, please share your manufacturer submittal sheet with us).

Keep in mind, we also manufacturer these "assembled" for distributors and for those who rather have an assembled plenum box. We have "assembled" versions listed on our website for sale.
