To be honest these curtains were a nightmare to fit, the bottom rail went ok but the top was way out of shape, so much so I thought this was the wrong item, it was nearly 2” shorter than the bottom rail which I couldn’t see why, I spent ages trying to un straighten the over bent ends to get the top rail to look anywhere close to fitting , I nearly gave up as I still don’t think I received the correct part but after 2 hours I got it somewhere handy to fitting, Iam an engineer so know about speeds & feeds in drilling & drill bits but this product was so far out of actual fit this isn’t a DIY fit product for the average person, take no notice of the You tube video as the reality is not close, for the price Iam disappointed as it was so far out of tolerance.
