Tekton Modular Wrench Organizers allow you to customize your organization system to fit your wrench collection perfectly. The tapered shape of the organizers fit a wide range of wrench sizes with consistent spacing between each tool. Durable polypropylene construction resists fuels and chemicals and has no sharp edges to scratch tools. Large wrench organizers can hold two tools and must be connected with another piece to hold three or more tools. Small wrench organizers must be connected with another organizer to hold more than one tool.
