Replaces The Entire Skylight Assembly In One Job

When a skylight starts leaking or the interior trim looks worn, replacing just one piece can leave gaps in coverage or mismatched parts. This kit includes both the exterior skylight and interior garnish, so you can handle the full replacement at once. The skylight seals the roof opening, while the garnish finishes the ceiling from the inside for a complete, matched install.

Stop a Troubling Leak Before It Spreads

When your RV skylight cracks and starts leaking during a storm or you notice water stains forming around the opening, the repair becomes urgent because water doesn't wait. This replacement comes with polycarbonate-safe sealant for installation, so you can apply a continuous seal on the roof surface and finish with a watertight barrier over the flange and fasteners. Once it's installed correctly, you're not chasing drips or watching water work its way into the roof.

Takes The Guesswork Out Of Replacement Sizing

A big part of replacing a skylight is confirming the opening size when the old unit doesn't provide clear measurements. Both the skylight and garnish are built for a 14" x 22" cutout, with outer flange dimensions of 17-3/4" x 25-3/4" on the skylight and 16" x 23-3/4" on the garnish. That gives you the key measurements before removing the old unit so you're not stuck mid-project with the wrong size.

Adds Needed Headroom In Tight Interior Spaces

A standard skylight setup can leave taller campers ducking in the shower or struggling to fit a deeper roof-to-ceiling opening cleanly. This kit uses a tall 6" outer skylight and an 8" inner garnish to create more usable space inside the opening. That extra depth helps it work with roofs 2-3/4" thick or greater, while also adding headroom where a standard low-profile setup just would not be enough.

Cleans Up Interior While Letting Light In

Replacing only the skylight can leave exposed foam and wood visible from the inside. The included garnish installs on the ceiling to cover those rough edges and create a finished look. Its white sidewalls hide construction materials, while the frosted top allows light through without being see-through. You get a tidy interior with natural light that feels softer and more private.

Holds Up Better to Constant Sun Exposure

Sun-baked plastic is usually what sends people shopping for another skylight in the first place. Both the skylight and garnish use UV-resistant polycarbonate that stands up to sun exposure without cracking or discoloring. Over time, that gives you components that keep their shape and appearance instead of turning brittle and worn after living on the roof.

Simple Installation With Included Sealant

Get a waterproof install using the included sealant approved for use with polycarbonate plastic. Remove the old skylight, then clean and prep the roof surface so it's dry and debris-free. For added sealing, apply butyl tape (sold separately) along the skylight flange before setting it in place. Secure it with 1" zinc or stainless steel screws (not included), then seal over the flange edges and fasteners with the included sealant. Install the garnish from the inside using 1" screws (not included) to complete the setup. If you need additional hardware or sealant, an install kit is available separately (SR76RR).

Note:

• Many sealants on the market, especially self-leveling sealants, contain a chemical known to weaken the polycarbonate. Please use the included sealant for installation. It is safe to use on all roof types and will not damage your skylight investment.
• Designed for roof thicknesses of 2-3/4" or greater to provide proper interior clearance.
