seal

Hi, I've just purchased a caravan for the first time and just getting my head around things. There's a few fixes to be done one being the following. I've noticed this seal is hardened and broken in places. What should I search for to replace this? From googling I've seen awning Rail protector...

Hello guys I'm new here so I'm sorry if this has t been posted in the right place :) I'm wondering of anyone can help me find the right awning rail insert/seal. I have a 2 birth alpine sprite xl that I'm renovating I'm unsure of the year it may be a 1992, basically at the moment I'm resealing...
