Measuring 25.2 in. x 16 in. x 7 in. overall, it comes equipped with 2 black panel boards (each 12.6 in. x 16.2 in.) and a diverse set of storage bins - 6 small red, orange, and blue bins (all 4.3 in. x 3.5 in. x 1.9 in.), and 12 large black bins (6.3 in. x 4.1 in. x 2.9 in.). Its highlight lies in the 4-color design, which facilitates easy differentiation of various tool types, while the lid-free design allows for direct visibility of contents. Crafted from brand-new PP material, these bins are strong and durable. The wall-mounted design significantly saves space, making it the perfect solution for organizing bolts, screws, nuts, hand tools, and more in garages or workshops. Furthermore, it supports DIY customization, allowing the 2-back boards to be installed independently or linked together into a larger unit using H -shaped connectors, catering to individual storage needs.
