Bay Window Tracks
A track can follow the architecture of a bay with far less visual weight than a decorative pole. Some systems bend on site, others are formed to the angles you supply, and the two are measured differently.
Ceiling fixing is often useful in a bay, where the wall between the windows gives little to fix into. Think about where the curtain parks when it is open, so the stack does not sit across the glass.
Bay mistakes are expensive. The free design consultation exists for exactly this.
