This suggested layout places most hooks on studs for maximum holding strength. Most residential wall studs are spaced 16" apart. The layout plan has a one foot high by 16" wide grid scale to help you position your tools. Start by placing shelf at desired height using three Jumbo Arm Hangers (A) and two Two-In-One Shelf Hangers (C). Beginning at the upper left side of the grid, match the tools you wish to organize with the hooks listed in the placement guide and shopping list. Place the tool and the hook against the wall and mark the mounting hole position(s). Fasten the hook to the wall. Before proceeding to the next hook, place the tool on the hook that you just mounted. This will help space all the hooks properly. Follow individual directions for mounting each hook. When mounting to hollow wall, sheetrock or wall board, use appropriate hollow wall fasteners.
