Swimming pool roller shutter mobile

If the pool is not a rectangle, the roller shutter Mobile allows covering the pool with an irregular rear wall thanks to the moving on rails up to the starting point of the cover at the widest part of the pool. Moving the shutter of the hiding position to finish position is easy and simple, a gentle push is enough.

I can see kids or grand ma tripping on that rail! is that permanent screwed in? can this cover-be used to warm up the pool as well like a solar cover?
