External Joint capping

[regnarts]

I am trying to find a replacement 32mm external white plastic capping for my Eldiss Aspire as per pic.
It fastens to a metal strip which covers the cab joint, the metal strip is screwed onto the innner timber frame.
Probably will need to buy both capping & metal strip together.
Has anyone got any idea where to buy this from please.

I imagine it's the same product that's used on Autotrail motorhomes. It's called D-capping and can be ordered via a dealer from Autotrail.

Probably also to be found on eBay.
