A strip of missing exterior trim can look much like the one beside it, yet take a different insert. Use this reference to identify the existing molding channel, insert width, colour and length before selecting a replacement. Photos and part numbers below link to the actual catalog listings so you can compare them with the piece removed from your RV.
Know which screw-cover width you removed
Compare the strip you have in hand against these size families. A width label cannot identify the under-edge profile or prove that a different manufacturer's channel will accept it.
Do not order by colour alone. White, polar white and colonial white are separate listed finishes. Check the original strip or a small hidden section of the RV, and compare the channel’s retaining shape before treating a part number as a match. Screw-cover inserts are not a repair for a leaking joint.

Identify an old RV trim insert in four steps
- Find a clean section where the old insert is still held firmly in place.
- Record the insert width and photograph both its face and the shape of its edges.
- Look at the channel itself for damage, missing fasteners or old sealant issues.
- Use the chart to shortlist the correct size and compare each linked product photo before ordering.
An insert may hide screw heads, but it cannot repair cracked molding, loose screws or a failed exterior seal. Address those problems separately before fitting replacement cover trim.
Compare the available inserts in photos
Identify 1-inch inserts
These one-inch options include short and bulk roll lengths; compare the colour and the old strip’s fit.




Identify 3/4-inch inserts
Compare the 3/4-inch insert family names and the physical retaining edges before choosing a length.



Identify 7/8-inch inserts
The 7/8-inch options have different colours and supplied lengths; look at the original strip, not the nearby trim.
