Quoya Smart Curtain Track- Bay/Curve Installation(Two Way Central Opening)- 135° & 90° Bends 

Might help if you spray some silicone lubricant inside the track and let dry before initial insert of the runners.

hi I am planning for 4 x 135 degree angles to allow for returns, at around 4.5 metre length. do you think I will hit issues with that ? Also how would I click a bay rail into the ceiling fasteners?
