I purchased the rubrail through Lagoon: Just 70€ per side for Lagoon 380!? Shipping cost more than doubled this.
It fit into a large platic tub as found in hardware stores. I added hot water and let it sit for at least an hour, leaving the tap open a bit so the hot water was constantly replaced and really hot.
Then I just pushed it over the scoops in one go and let it cool for a few hours. Once cool it retained the new shape and it was easy to take the lowest part off again, add some sika, and push it on again. Last thing was cutting the trim at the ends, and fixing it with the screws.
Easy job as long as you have access to (unlimited) hot water.?
