Replace or add a horizontal slider RV window with the Lippert 8800 Series RV Window — Horizontal Slider, Radius Frame, 18" × 22". 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.

Horizontal Slider Design

Horizontal sliding operation — the window slides open horizontally for ventilation. Can be installed on driver or passenger sides of your RV. Includes a fine mesh screen to keep insects out while allowing airflow.

Radius Frame Style

This is the radius (rounded corner) frame variant with a 3.125" corner radius for a precise, contemporary aesthetic used in most modern RV builds.

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, saving energy and costs.
