Roof light (1 Viewer)

[Nigel Crompton]

This 2015 Hymer has 2 roof lights, make unknown. They're not hinged, they go up and sideways so the lid is always parallel to roof.

Problem: the mesh insect screen roller has lost all tension, and needs sorting.

I've had the two end-plates off - expecting to find fixings hidden under them, but nothing. Not a screw in sight.
The 2 side pieces look like they may pull off, but I'm loathe to use force.

Anyone been here before me ?

is that a rubber 'cord' in a groove holding it in?

There's a cord that the concertina blind runs on, but the flyscreens are just 'in the groove'
