concrete and masonry walls only. not for drywall.the supplied screw fasteners are concrete anchors.I took it to a hardware store...Imagine: a hardware store full of products for attaching things onto drywall and nothing works with this product.total waste of time.probably works great if attaching to a cinderblock or brick or concrete wall.
