This is the floating shelf kit only. You can purchase the mounting hardware from us as well depending upon if you are installing this into wood/drywall or concrete. It is very important that for the most secure installation these cables are NOT mounted into just drywall with anchors. There should be actual support for these cables as they support the weight of the items as well as the system itself. If necessary spanners must be inserted between ceiling joists to secure the unit properly. NOTE: Each kit requires 8 anchor kits to be mounted.
