This Dust Guard / mesh window encloses the back of the cab and in doing so dramatically reduces the dust in the cab while providing rear protection from the elements. There is also included two fire resistant seat dust guards that install under the two front seats. As you already know the majority of the dust comes from behind and under the two front bucket seats. The Dust Guard reduces this problem. Installing the Dust Guard is a breeze. There is no drilling required. It takes under 15 minutes to install. Just a few velcro straps to fasten together, that's all! The Dust Guard is made of the following: Main Body & mesh window: fiber glass reinforced vinyl & fiberglass reinforced mesh. Seat dust guard: 1/4" fire resistant foam ( facing into the engine compartment ) & vinyl (facing up). Cleans easily: Wash with mild soap and hose off. Important .. Please note: * If the roll cage has been modified or a aftermarket roll cage has been installed the Dust Guard will not fit.
