Lippert12" x 21" GlassRadius Entry DoorLippert 363369 Inner & Outer Window Frame with Seal and Glass -- Radius Entry Door Replacement, 12" x 21", White

A direct OEM-style replacement window frame for Lippert radius RV entry doors, this assembly ships ready to install with the obscure glass pane and seal already integrated. No fabrication, no glass sourcing -- just swap the damaged or deteriorated unit out and restore your door's appearance and weather resistance in one step.

Complete Frame-and-Glass Assembly for Lippert Radius Doors

When an RV entry door window cracks, fogs, or loses its seal, replacing the entire inner and outer frame assembly is the cleanest fix. Lippert's 363369 bundles both the interior and exterior frame halves, the weatherproof seal, and the obscure glass pane into a single, pre-assembled unit. The obscure (privacy) glass is standard for entry door applications, providing natural light while maintaining interior privacy.

The frame is molded from high-impact polystyrene (HIPS), the same rigid, lightweight thermoplastic Lippert uses across its door line. White finish matches factory Lippert radius door trim. Overall installed footprint is 15-3/4" wide by 25" tall, with a 12" x 21" glass viewing area.

Complete Assembly

Includes inner frame, outer frame, pre-fitted seal, and obscure glass pane. No additional components required to complete the window opening.

High-Impact Polystyrene

Rigid HIPS construction resists cracking and warping under normal road vibration and temperature swings typical of RV use.

Obscure Glass Pane

Factory-style privacy glass diffuses light without blocking it -- standard for entry doors on travel trailers and fifth wheels.

DIY-Friendly

No special tools or assembly required. Frame halves sandwich the door panel from inside and outside, held by the existing door structure.

Drop-In Replacement: This unit is designed specifically for Lippert radius-corner entry doors. The frame halves clamp around the door panel cutout and are secured with fasteners (not included). If your existing door already uses a 12" x 21" opening with radius corners, this assembly should fit without modification.
Verify Your Opening Before Ordering: Lippert produces radius entry doors in multiple window sizes. The glass dimension (12" x 21") is the key measurement -- measure your existing glass or rough opening, not the outer frame. The outer frame of this unit measures 15-3/4" wide x 25" tall. Confirm both dimensions match your door before ordering.
Installation Hardware Not Included: Screws, clips, or other fasteners needed to secure the frame halves to your door panel are not included with this assembly. Use hardware matching your existing door fastener specification or source replacements from a hardware supplier.
Maintenance Tip: Inspect the frame-to-door seal annually and after any hard driving season. HIPS frames can develop micro-cracks at corners if exposed to prolonged UV without a protective coating. A UV-resistant plastic protectant applied to the exterior frame face will extend service life.

Important Information
  • This frame is designed exclusively for Lippert radius-corner entry doors. It is NOT compatible with square-corner door frames or non-Lippert door panels.
  • Verify your existing glass or rough opening measures 12" wide x 21" tall before ordering. Ordering an incorrect size will require a return and may delay your repair.
  • Installation hardware (screws, clips, fasteners) is NOT included. Source appropriate fasteners to match your existing door hardware.
  • Consult your RV's owner documentation or measure the existing frame to confirm the correct size -- Lippert offers this window assembly in multiple sizes.
  • Handle glass pane carefully during installation. The obscure glass is not tempered safety glass; breakage during rough handling will require a replacement unit.
  • Weight: 2 lbs assembled. No extraordinary structural support is required during installation.
