The Tool Sorter wrench tray - made in the USA - is compact, portable, and fits in most standard tool chest drawers. Store up to 28 wrenches from 7mm - 1/4" (length up to 6.5?) to 19mm - 3/4" (length up to 9.5?). Detailed measurements of the storage area are shown in one of the pictures of this listing. Unique, integrated sorting bar makes sorting while storing quick and easy - slide the wrench, flip it and it is stored in the right place. The sorting bar accommodates both SAE and metric. Tray measures 13.5" x 10" x 1.5" and is made of sturdy ABS plastic. Wrenches lie in organizer but are not clipped in place. This organizer is an improved version of the previous Sortatool tray and works better with shorter wrenches. Reviews highlight the quality of the product and its storage capacity. This tray is great for anybody with wrenches scattered in tool chests or boxes. The organizer works well with different wrench sets or brands, but certain types like ratcheting wrenches with thicker ends may not fit. Please contact us or make use of the customer questions & answers section to find out if your tools will fit. To avoid frustration and disappointment: Before placing an order, please measure your tool drawer or tool box to make sure that the tray fits. Please note that wrenches sit in storage slots but are not held in place with a clip or magnet in the organizer!
