Specialty Recreation RV Skylight Kits, Domes & Opening Size Guide
Need an RV skylight but unsure whether to order an exterior dome, an interior liner or a complete kit? Specialty Recreation offers several different parts for common 14 × 22-inch roof openings, plus 14 × 14-inch exterior skylights. The charts below separate these choices so you can shop by part number and check the measurements that matter.
Three measurements to check before buying
Understand the main Specialty Recreation skylight types
A 14 × 22-inch opening refers to the roof cutout. For most SL1422 exterior models the flange measures 17½ × 25½ inches; N1422 inner domes use 16 × 24 inches. Check these dimensions independently instead of assuming any two domes are interchangeable.
Specialty Recreation MPN and size chart
These verified manufacturer opening and flange measurements identify the exact pieces listed in our catalog. The same 14 × 22-inch opening can accept multiple styles only when the profile, flange and installation requirements also suit your RV.

Choosing between the most similar part numbers
What is the difference between K1422BLP and SL1422B-LP?
K1422BLP is a complete bronze exterior/white interior kit including sealant. SL1422B-LP is the bronze low-profile exterior roof skylight only.
Are N1422 and N1422D the same product?
Both are interior components for 14 × 22-inch openings, but N1422 is white and approximately 4 inches high, while N1422D uses a clear bubble in a white frame and is approximately 5 inches high.
Will a 14 × 22-inch skylight fit any 14 × 22 opening?
Not automatically. The opening dimension is only one measurement: compare flange coverage, profile, roof thickness and installation requirements for the exact MPN.
Related roof-care and skylight references
For light and temperature control inside the RV, review the Camco roof vent insulator and skylight cover comparison. Before installing a new exterior dome, examine the roof membrane, existing sealant and mounting surface.
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.
