Availability Of End Caps For Side Rails On Retrax XR Tonneau Cover  

Updated 01/12/2026 | Published 09/02/2024

Question:

I have a Retrax XR tonneau cover and I am looking to replace the end caps on the rails as they have disintegrated in the sun. Are these available for purchase without buying the entire side rails? Thank you for your help Zach The end caps are shown on the rails in this link. https://www.etrailer.com/Accessories-and-Parts/Retrax/RTT-82383.html

Hello Zach. We get this question from time to time and according to Retrax the end caps are not available separately. So, the only way to replace them replace the entire rail.
