Wosijm RV Entry Door Window Kit 12×21 Low-Profile Shade Black — Lippert-Compatible, Pre-Drilled

Wosijm 806621 is a complete RV entry door window kit with a low-profile sliding shade, sized to fit a 12" W x 21" H inner glass opening and designed for Lippert-compatible RV doors.

This all-in-one replacement window assembly gives motorhome and camper owners a high-view glass area, weather-deflecting frame design, and a smooth, low-profile sunshade for privacy and light control. The outer frame measures 24.75" × 15.75" while the inner glass viewing area is 12" by 21", delivering over 70% glass-to-frame ratio for better daylighting and an unobstructed sightline. The kit arrives with pre-drilled mounting holes and all required hardware, letting most DIYers complete installation with only a screwdriver.

Will this window fit my Lippert-compatible RV entry door?

Yes — the Wosijm 806621 is engineered for wide compatibility with Lippert-style entry doors and many common RV, trailer, and camper doors. Confirm your existing inner glass dimensions match 12" × 21" and check the outer cutout accommodates a 24.75" × 15.75" frame to ensure a proper fit.

• Inner glass size: 12" W × 21" H (viewing area over 70%).
• Outer frame footprint: 24.75" × 15.75" for door cutout planning.
• Works as a replacement for entry, storm, and screen doors with similar sizing.
• Pre-drilled mounting holes match common Lippert door placements.

How easy is installation for a non-professional?

Installation is intended to be straightforward for a homeowner with basic tools. The kit includes mounting hardware and pre-drilled holes to speed alignment; most installations require only a screwdriver and under an hour of work.

• All screws and accessories included in the package.
• Pre-drilled holes simplify positioning and reduce guesswork.
• Screwdriver-only install for many doors, no specialist tools required.
• Clear sizing helps you check fit before committing to the swap.

What does the low-profile shade do, and how does it operate?

The built-in sunshade provides adjustable light control and privacy while maintaining a slim appearance on the door. It glides smoothly along its track without sticking or jamming, allowing quick movement to block direct sunlight or obscure the view from outside.

• Smooth sliding mechanism for effortless adjustment.
• Low-profile design keeps the shade discreet and compact.
• Offers privacy and sun blocking without adding bulk to the door.
• Durable components designed for repeated operation in RV environments.

How does the frame handle weather and water?

The frame features a water-diversion profile that helps channel rain away from the door opening and reduces moisture intrusion. That design, paired with quality sealing at the perimeter, helps limit drafts and protect the interior from water damage.

• Engineered water drainage channels divert rain from the door seam.
• Helps reduce moisture erosion and block cold drafts.
• Sturdy frame materials suitable for mobile use and outdoor exposure.
• Complements door insulation when paired with proper sealing tape or caulk.

Who this product is for: RV and camper owners replacing damaged door glass, upgrading to a larger viewing area, or adding a built-in shade for privacy. It's also a practical choice for DIYers who want a Lippert-compatible, easy-to-install window kit that balances daylight, weather protection, and a compact shading solution. If you need precise sizing (12"×21" inner glass) and a ready-to-fit assembly with included hardware, the Wosijm 806621 is designed to meet those needs without a tradesperson.
