These plastic trim strips are inserted in aluminum extrusions going down the sides of Airstreams, Argosys and other vintage trailers.
Measure the exposed portion of the vinyl insert to determine width. For example, the 1/2" insert has an overall width of just over 5/8". They may bow out slightly when installed so when in doubt you need to go just a touch bigger.
For best results, we recommend installing the moulding while temperatures are between 50 and 70 degrees F.
- 1/2" Version has an exposed width of .54" and an overall width of .68"
- 1" Version has an exposed width of 1.01" and an overall width of 1.14"
- 1-1/2" Version has an exposed width of 1.51" and an overall width of 1.61"
Please note: All plastics on the outside of a trailer are susceptible to UV damage. We highly recommend wiping plastic inserts with 303 Aeorspace Protectant once or twice each year. 303 Protectant contains UV inhibitors.
