I waited 2 months for delivery. The installer (XPO who came at 8:30 pm on a friday - 3 hrs late) said my studs were 21" apart so I needed the wider bracket. I contacted Tonal and let them know the situation and XPO said they would come back out with the wider bracket. They came out 2 weeks later and the installer had no idea what I was talking about and did not have the wider bracket. At this point I have no faith on this company's ability to properly install.
