The LD-356 heavy-duty plastic tool box storage case is engineered to organize, protect, and transport hand tools and hardware in demanding workshop, jobsite, and garage environments. Constructed from high-impact polypropylene (PP) or ABS plastic, the case body offers excellent resistance to drops, impacts, moisture, and temperature fluctuations, ensuring that stored tools remain secure and accessible even under rough handling conditions. Reinforced metal hinges and latches, paired with zinc-plated steel hardware, provide long-lasting durability where plastic-only fittings would fail, while the rubber grip handle delivers comfortable carrying even when the box is fully loaded.

The LD-356 series is offered in four size options to accommodate a wide range of storage needs. The small 12x8x6 inch case is ideal for organizing small hand tools and accessories, while the medium 16x10x8 inch and large 20x12x10 inch cases suit general mechanic and electrician kits. The extra large 24x14x12 inch case provides ample capacity for comprehensive tool sets and bulky equipment. Each case features a stackable nesting design that maximizes storage efficiency in vehicles, on shelves, and in workshop cabinets, allowing multiple units to be securely stacked without sliding.

Available in a variety of color combinations including black with yellow lids, black with gray lids, red with clear lids, black with orange lids, and all-black configurations, the LD-356 can be tailored to match brand identity or color-code tool categories for quick identification. The clear-lid option enables instant visual inventory without opening the case, a popular feature for retail display and field service applications. The branded exterior and reinforced corners further enhance both the professional appearance and structural resilience of each unit.

Quality is validated through drop testing, hinge cycle testing, and load capacity verification on every production batch. The LD-356 carries CE, ISO 9001, and SGS certifications, supporting compliance with international quality and safety standards for global distribution. With a minimum order quantity of 200 pieces, a production lead time of 15 to 25 days, and support for mixed orders across sizes and colors, the LD-356 is an excellent choice for retailers, distributors, and OEM brands seeking durable, stackable tool storage solutions at competitive wholesale prices.
