Lippert 8800 RV Window | Vertical Slider Square Corner | 18"×24" | Kit

Replace or add a vertical slider RV window with the Lippert 8800 Series RV Window — Vertical Slider, Square Corner Frame, 18" × 24". Complete replacement kit with tempered tinted glass, aluminum corrosion-resistant frame, integrated water weep system, and everything you need for installation. Proudly cut, tempered, and assembled in Indiana.

Vertical Slider Design

Vertical sliding operation — includes a fine mesh screen to keep insects out while allowing airflow.

Square Corner Frame Style

This is the square corner frame variant — a cleaner, more angular aesthetic used in specific RV builds. If your existing installation uses rounded corners instead, see the radius frame variant.

Heavy-Duty Construction Built to Last

• Tempered glass — resists cracking, chipping, and shattering
• Tinted glass — blocks sunlight, reduces heat, and enhances privacy
• Aluminum frame — resists corrosion and extends window lifespan
• Latching mechanism and sealing gaskets keep your RV secure and dry
• Built-in water weep system directs water away from the window

Energy Efficiency Benefit

Tinted glass and quality seals help maintain comfortable interior temperatures — reduces reliance on heating and cooling.
