View matching productRV Skylight Domes, Inner Garnish & Size Parts Guide
Identify RV roof skylight outer domes, interior domes and garnish trim rings by the actual model and manufacturer part number. A skylight specified for a 14 × 14 or 22 × 14-inch roof opening has a larger mounting flange. Outer domes and inner domes have separate weather-sealing and finishing roles.
Manufacturer shape and dimension references
Review ICON's original RV skylight illustrations and inner dome listings for factory dimensional drawings. The SL1422 skylight family identifies the related 22 × 14-inch outside and inside component families. Use the manufacturer's final specifications to select the actual flange and dome rise, not the photograph alone.
Use the component map to locate the dome, garnish and mounting areas; compare dimensions with your existing skylight.
Parts-location reference
Weather-facing skylight attaches to the roof curb or deck. Confirm total flange, hole pattern, dome rise and original roof construction.
Optional interior clear diffuser/thermal air-gap component. Depth can differ: 01981 is listed at 5 inches, 12149 at 2 inches.
Interior finishing trim, such as ICON 01936. This is not an exterior weather cover and should not be used as a roof seal.
Use sealant and fasteners approved for the skylight material and roof membrane, not an assumed universal caulk. Polycarbonate compatibility matters.

12573 — Interior skylight trim ring
A different trim-ring listing; confirm physical dimensions before pairing with another ICON dome.
View matching product14 × 14 versus 22 × 14 opening
The 14 × 14-inch outer dome parts (01817 white, 01818 clear, 12116 smoke) are distinct from SL1422 exterior skylights (01819 white, 12080 smoke, 12555 dark smoke). Neither is a substitute for the separate interior SL1422 garnish 01936 or clear inner domes 01981 / 12149. A roof opening measurement alone does not prove mounting-flange or dome-height compatibility.
Match the skylight trim and mounting flange
ICON 12573 is a 16-inch trim ring, whereas 01936 is the inner garnish for the SL1422 skylight family. Do not treat these as interchangeable based on size alone. Match the existing skylight model, inner opening, flange, fastening pattern and garnish depth. Skylights from different manufacturers may require different mounting and sealing arrangements.
For additional ICON sizes not covered here, see the NSL208 20 × 8-inch neo-angle and SL2222 22 × 22-inch skylight reference, including the exact 15159 mounting screw pack and 12062 skylight sealant.
Leak prevention: Do not drill a skylight or seal stressed plastic with an incompatible primer or solvent. Follow the dome manufacturer's instructions and use the roof flange and termination sealing reference for identifying sealant functions. Inspect the roof curb for water damage before replacing only the dome.
