This heavy duty steel shelf bracket is epoxy coated and has a 1000 pound load rating per pair. It is recommended that you fasten this bracket to the wall (in or through a wooden wall stud) with 5/16in.x3in. long lag bolts (not included). Ideal for counter tops, work surfaces, book shelves or anywhere a large load capacity is required. These are bulk packed, not carded or poly-bagged, so slight imperfections may appear on the bracket due to shipping.
