Which brand of sliding doors do I have?

[Jef & Marin, Netherlands]

The solid plastic sliders of our sliding doors are worn out and need to be replaced. I would like to contact the unknown manufacturer. Can someone point me in the right direction?
The boat is a Switch 51 catamaran of 2003. This model was produced from 1999 until 2007, in the south of France by Sud Composites. The sliding doors have probably been made by a company in France or Italy.
Thanks for your help.

Don't know the brand but it appears you are missing the roller.
Those are generic items, designed to be replaced.

Any glass repair or locksmith shop should be able to fix it or steer in the right direction.

The fuzzy weather stripping looks exactly like the type we use in Canada, made by Shlegel.
