Stackable Rotomolded Tool Box for Professional Workshop Organization

Product Overview

The WNRLN RTB-2200ST is a purpose-engineered stackable rotomolded tool box designed to solve the universal workshop challenge: maximizing storage capacity in limited floor space. Through precision-molded interlocking lugs on the lid and base, multiple units stack securely up to five high without straps, dunnage, or external racking — effectively multiplying storage density by 400% in the same footprint.

Unlike consumer-grade stacking bins that wobble and collapse under load, the RTB-2200ST features an engineered interlocking system where each unit positively engages with the one below and above it. Molded-in stacking lugs with a 15mm engagement depth provide mechanical registration that resists lateral shifting during transport, forklift handling, and seismic events. Each unit is independently tested to support 600 kg of static top load.

Key Features

• Precision Interlocking Stacking System: Molded-in male/female stacking lugs with 15mm engagement depth create positive mechanical interlock between stacked units. The interlocking geometry resists lateral displacement during transport vibration and forklift handling.
• 600 kg Static Load Capacity: Each unit is engineered to support 600 kg (1,320 lbs) of static top load, enabling five-high stacking of fully loaded tool boxes without structural deformation or compression of lower units.
• Forklift and Pallet Jack Compatible: Integrated forklift tine pockets at standard 27-inch centers enable mechanical handling of loaded stacks. The flat base design is compatible with pallet jacks and roller conveyor systems.
• Recessed Carry Handles: Spring-loaded handles sit flush against the case body when not in use, maintaining the flat exterior profile essential for tight stacking and truck-pack efficiency. No protruding hardware to snag or damage adjacent units.
• Modular System Expandability: Standardized external dimensions across the RTB product family allow mixing of different sizes within the same stack, enabling flexible organization systems that grow with operational needs.

Technical Specifications

Workshop and Warehouse Applications

• Automotive Service Centers: Organize specialized diagnostic tools, pullers, and calibration equipment in labeled, stacked tool boxes for rapid access by multiple technicians.
• Industrial Maintenance Departments: Create tool crib systems where each maintenance trade (electrical, mechanical, hydraulic) has dedicated, color-coded stacked storage.
• Construction Job Trailers: Maximize limited trailer space with secure stacked storage that stays in place during transport between project sites.
• Distribution Warehouses: Organize spare parts inventory in stackable containers that integrate with existing pallet rack and shelving infrastructure.

Why Choose Our Stackable Tool Box?

Our interlocking stacking system eliminates the instability, wasted space, and safety hazards of improvised stacking solutions. Each unit is engineered through finite element analysis to ensure uniform load distribution across the stack. The rotomolded construction provides the structural rigidity needed for multi-high storage while remaining 40-60% lighter than equivalent-capacity metal cabinets.

Packaging and Shipping

Each stackable tool box is individually wrapped in protective film, packed in branded color box, and shipped in reinforced export cartons. Master cartons are palletized with corner protection for secure international freight transport.

COMPANY PROFILE

            Our factory is located in Fengxian industrial zone, Shanghai which is 30 minutes by car to the Hongqiao airport and set up in year 2011. We specialized in manufacturing and designing a wide range of rotational molds and products. Our plant covers an area of 9000㎡ with more than 100 employees, 5CNC machines, 20 sets of rotational machines and 15 manufacture processing lines. With 1500 sets molds and 800tons rotational mould products yield per year, our products have been exported to all over the world such as countries Russia, Ukraine, Uruguay, Salvador, UAE, Saudi Arabia, Zimbabwe, Turkey, Australia, New Zealand, Brazil, Chile, and South Africa. With the belief that quality is the lifeblood of development, TOPGREEN won a good reputation in both domestic and foreign countries.

PART ONE FOOD TRANSPORT EXPERT

              Under the requirements of multi-level industries, we has researched and developed low-cost, high-quality, and versatile thermal insulation products to serve the catering industry, government agencies, social groups, student groups, hotels, cars, and households. , Transportation and outings, sports, camping, hunting, fishing, long-distance travel and military logistics support, etc. There are 7 series of nearly dozens of products under the brand TOPGREEN, including: electric food transport carts, non electric food transportation carts, insulated front loading food pan carriers, insulated top loading food pan carriers, insulated beverage transport barrel, dish caddy and ice caddy. At present, in the domestic catering distribution industry, the most difficult to control is temperature. According to the food safety certification system (HACCP) required by the World Health Organization, it is proposed that ‘food must be lower than 10 degrees Celsius or higher than 65 degrees Celsius during delivery’ to ensure food safety. True to this problem, our company has developed and produced nearly dozens of products to solve the safety of food in the distribution.

PART TWO COLD STORAGE SPECIALIST

              Coolers are used for keeping cold items for long time, such as beverages, meat, fish, seafood , vegetables, fruits. Nowadays, coolers have been widely used in cold chain logistics, catering industry, fishing industry, and outdoor activities.
