Kinro RV Window Replacement — Sizing, Cost & Lippert Equivalents

Kinro is one of the highest-volume RV and manufactured-housing window brands, standard on a large share of travel trailers and fifth wheels. Kinro windows are sized by rough opening, so a replacement is ordered by opening dimensions rather than a model number. Glass-only replacement runs $150–$400; a complete Kinro-style window runs $300–$750 installed. Kinro is now part of Lippert, so current Lippert units are the direct equivalents and generally drop into the same cutout.

What they make: Aluminum and vinyl-framed sliders, torque-lock windows, entry-door glass, egress windows

Typical cost: $150 – $400 glass only · $300 – $750 complete window

Kinro sizing is rough-opening based

Unlike coach windshields, Kinro trailer windows are catalogued by the hole in the wall, not the glass. A "30x22" is a 30-inch-wide by 22-inch-tall rough opening. Measure the opening itself, not the glass and not the outer flange, and confirm the wall thickness so the flange and clamp ring clamp correctly.

Standard sizes are stocked, which is why a trailer window is often a three-day job while a coach windshield is a three-week job. Non-standard openings are custom-built and add two to four weeks.

Measure rough opening width x height
Measure sidewall thickness for the clamp ring
Note radius corners vs square corners
Confirm tint: clear, gray privacy, or bronze
Check whether the unit is egress-rated (bedroom windows)

Egress windows have rules you cannot ignore

Bedroom exit windows must meet minimum clear-opening dimensions and open with a single motion. A replacement must be egress-rated too — swapping an exit window for a standard slider of the same size creates a code and safety problem and can be flagged at resale or insurance inspection.

Order egress-rated when the original was egress-rated. It is identified by the red release latches and the emergency exit decal on the glass.
