Features 23 storage spots, each sized with ½” Diameter holes (12.7 mm) to fit all of your large screwdrivers and other tools. The holes will easily accommodate larger sized 10-in-1 or similar screwdrivers which often do not fit in other storage systems. This screwdriver organizer is 18" x 3" x 3" (457mm x 76mm x 76 mm) and is made out of ¼” (6 mm) plywood, is unfinished, and laser cut/engraved locally in the U.S.A. Corners are finger-jointed and glued together for a sturdy construction that is also lightweight and easy to mount. Mounting holes are 16 inches apart for typical wall anchoring, can also be installed on a pegboard, cabinet door, or however your garage is organized. Easily grab the tool you are looking for without rummaging through a messy toolbox drawer. Due to the nature of natural wood, there will be slight coloration and grain differences with each piece.
