You asked we listened.
As described on the Floating Shelf pages all orders come with steel rods to install shelving into wall studs. We love doing it this way because this method holds a lot of weight. However, we do have many customers who have steel framed homes so this solution doesn't work. Or customers who feel more comfortable using brackets and installing those into wall studs.
So we have searched high and low to come up with the right solution, that we are happy to recommend.
As always, install is up to the discretion of yourself and your tradesperson.
