Lippert / LCI 12" x 21" Made in the USA Lippert 363369 Inner and Outer Entry Door Replacement Window Frame with Seal -- White, 12 x 21 in.

When your RV entry door window frame cracks, warps, or loses its seal, moisture and drafts follow. This Lippert OEM replacement kit gives you both the inner and outer frame halves plus the integrated seal, so you can restore a clean, weather-tight window opening in minutes -- no tools, no hardware, just snap the two halves together.

The Right Fix for Worn LCI Radius Door Frames

Lippert (LCI) radius entry doors are standard equipment on a wide range of travel trailers, fifth wheels, and motorhomes. Over time, the plastic window frame takes abuse from road vibration, UV exposure, and repeated opening and closing. Hairline cracks let water track behind the door skin; a degraded seal kills your insulation. Replacing the frame with this direct OEM part restores the original fit and seal without modifying the door.

Part number 363369 covers both the inward-facing and outward-facing frame rings as a matched set. The two halves sandwich the door panel and click firmly into place. No adhesive, no screws, no special tools -- the snap-together design means this is a realistic DIY job at a campsite or in the driveway.

Snap-Together Install

Inner and outer halves lock together through the door panel -- no hardware, no drilling, no adhesive required.

Integrated Seal Included

The frame ships with its weather seal already in place, so you get a complete, ready-to-install assembly out of the box.

OEM LCI Fitment

Designed specifically for Lippert radius RV entry doors -- not a generic trim ring. Matches the original opening geometry and appearance.

Made in the USA

Manufactured domestically and backed by Lippert's limited 1-year warranty for peace of mind on the road.

What Is Included

  • 1 x inner window frame half (white)
  • 1 x outer window frame half (white)
  • Integrated weather seal (factory-fitted to frame)
No hardware needed. The snap-together design means you can complete this replacement without removing the door from the RV or sourcing any additional fasteners.

Fitment -- Is This the Right Frame for Your Door?

This frame is designed for LCI radius-style RV entry doors with a 12 in. wide x 21 in. tall window cutout. Before ordering, measure your existing frame opening (not the glass) from the inside surface of the door. If your door has a different window size or uses a flat (non-radius) door style, this part will not fit correctly.

How to measure: Measure the opening in the door panel where the existing frame sits -- width first, then height. For radius doors the corners have a curved profile; a square-cornered cutout indicates a different door style that requires a different part.

Installation Overview

  1. Remove the existing inner frame half by pressing the locking tabs inward and pushing the frame out from inside the RV.
  2. Pull the outer frame half free from the exterior side of the door.
  3. Clean the door panel opening of any old seal debris or moisture.
  4. Position the outer frame half on the exterior surface of the door, aligning it with the window cutout.
  5. From inside the RV, press the inner frame half into the opening and engage the snap clips against the outer half until you hear/feel each clip lock.
  6. Verify the seal runs continuously around the perimeter with no gaps.
Heads-up: The glass or acrylic window pane is NOT included with this frame kit. If your existing glazing is scratched, cracked, or missing, source the correct pane separately before installation.
Maintenance tip: After installation, apply a UV-protectant spray to the exterior white plastic every season. RV door frames are fully exposed to sun and road grime; a protectant slows yellowing and keeps the plastic from becoming brittle.

Important Information
  • This frame fits LCI radius RV entry doors with a 12 in. x 21 in. window opening only. Verify your opening dimensions before installation.
  • The window pane (glass or acrylic) is NOT included. Do not install the frame without the pane seated in position -- an open frame does not provide a weather-tight seal.
  • This is a snap-together replacement frame, not a complete entry door. It will not repair structural damage to the door itself.
  • Inspect the snap clips during installation. Forcing a misaligned clip can crack the plastic. Align all clips before pressing firmly.
  • Not intended for use on flat-panel (non-radius) entry doors or on passage doors other than the main entry door style specified by LCI.
