The Lippert 8800 Series 12" x 22" Vertical Slider Window is a space saving solution designed for smaller RV side openings. Built with durable tinted tempered glass, it helps reduce interior heat and minimize glare, while standing up to road vibrations and outdoor exposure. The sturdy aluminum frame is engineered to resist rust and maintain structural integrity over time. Installation is simple with the included trim ring, screws, and foam seal. The integrated drainage channels and sealing gaskets help direct water away from the frame to protect against leaks and moisture intrusion. Its vertical sliding design allows for adjustable airflow, giving you control over interior ventilation. A fitted mesh screen keeps insects out while allowing fresh air to circulate. Compatible with a variety of wall thicknesses, this compact window delivers dependable performance with a clean black finish that complements most RV exteriors.
