SPUR® Steel-Lok 150mm Steel Shelf supporting bookends are designed to support our steel shelf range offering a bookend at either at the end of a run or to enable the shelves to be adjusted independently as the connection is one of the lines of slots. They are made from the same 1.5mm thick steel as our standard brackets and offer superb strength due the distance between the support hook and base of bracket known as the moment conection. Finished as standard in our Spur Frost White these can be coated in other colours as a special.
