A modern concrete shelf or shelves to compliment your fireplace or accent your wall. It is made to look like a heavy concrete beam, but is a hollow design and light with easy installation. Our mantels hang using the classic L-Shelf hanging system. There is no stronger way to hang shelves like this, hence no screw holes that can be seen. Each Floating Shelf will have its own unique look as it's all hand made. - These are available in standard sizes of 8 Depth x 5.75 Height - Standard lengths of 48", 60" and 72" are available. - These come with all mounting hardware. Thank you for stopping by our shop for a stone beam!
