When fixing a wardrobe system to stud or brick walls, you will need to order these anchors for every screw that you use. If ordering 911 or 980’s, you will not need anchors to use with this hardware as they already have pre loaded anchors. Any other wall brackets, or shelf support brackets you will need to anchors to go with the screws. We sell them individually so please make sure you order the correct amount. These anchors are made from grey plastic.
