Identify Specialty Recreation RV Skylights

A damaged or discoloured RV skylight may leave you trying to identify an old dome without a readable part number. Specialty Recreation makes exterior domes, interior liners and complete replacement kits with different profiles, colours and mounting flanges. Use the opening and the old part's role to narrow the selection before comparing exact MPNs.

Identify what is still installed

1. Measure the roof cutoutMeasure the actual rectangular hole beneath the skylight. A visible outer flange is larger than the roof opening.

2. Compare both surfacesLook at the rooftop exterior dome and the interior ceiling part separately. A clear inner dome, white liner and exterior dome are different replacement pieces.

3. Compare height and finishMeasure available roof/ceiling depth and the original dome profile. Bronze, ice, clear, smoke and white are not interchangeable part numbers.

Why the same opening size can have different parts

Outer dome versus inner linerThe SL1422 family is used on the roof exterior, while N1422 and N1422D are interior skylight parts. Their flanges differ even though both reference a 14 × 22-inch opening.

Kit versus individual replacementK1422 kits include an outer and inner component plus sealant. An SL1422 exterior dome or N1422 interior component is not the same quantity or assembly.

For example, the common 14 × 22-inch exterior dome flange is 17½ × 25½ inches, while the N1422 inner dome flange is 16 × 24 inches. The tall K1422WT outer flange is slightly larger at 17¾ × 25¾ inches.

Checking an older installation: A matching rough opening does not establish the correct part. For an exterior replacement, compare flange coverage, dome height and attachment method. If the inner liner is also damaged, a complete kit may be a better match than an outer-only part.

Common skylight identification questions

Is K1422WLP the same as SL1422W-LP?

No. K1422WLP is a complete white outer-and-inner skylight kit with sealant; SL1422W-LP is the white low-profile exterior dome. The part-number prefix changes what you are ordering.

Why are two N1422 inner skylights different heights?

The manufacturer lists N1422 as a white 4-inch inner component and N1422D as a clear-bubble inner component with a 5-inch height. Both have 16 × 24-inch flanges for 14 × 22-inch openings.

Can I replace just a cracked outer skylight?

Often you can buy an exterior SL-series dome separately, provided its size and mounting method are a correct match and the remaining inner parts are serviceable. Examine the entire assembly and follow manufacturer installation instructions.

For other skylight brands, see the RV skylight dome and inner garnish size guide and the ICON skylight parts reference. For weatherproofing information, see RV roof sealants, flange and butyl-tape parts.

For original sizing tables, consult Specialty Recreation's skylight catalog (PDF). The manufacturer also provides K1422WT extra-tall kit dimensions and clearance requirements. Use the approved sealant and installation method specified for your skylight and roofing system.
