A10-3300 by Valterra is a white louvered vent cover designed for recreational vehicle battery compartments. It helps direct battery gases and fumes to the outside of the RV while the louvered design helps keep rain and debris from entering the vent opening. Made of plastic, this replacement cover measures approximately 4-1/4 inches by 4-1/4 inches and accommodates a compatible 1-3/4-inch vent hose assembly. It is designed to replace the cover on a compatible Valterra battery box vent; the vent body may be sold separately.
