They are a bit of a fiddly to fit and definitely needed 2 of us to make sure we had them in correctly. Be careful with the butterfly bolts if fitting into dry wall. Ensure they are full opened behind the wall before tightening. Other problems can arise as we can testify! Once they are fitted, they seem to be very study and certainly create more space inside the wardrobe for all our things. Quick service from Wayfair.
