The RK Box Air container in recycled polypropylene, an integral part of Linea 391, has been developed for professional applications where durability, sustainability and flexibility are essential requirements. The optimised design allows efficient use at workstations and in storage areas. The reinforced-base structure ensures resistance to stress and heavy loads, while the wide open front area optimises picking operations. The tapered design and support inserts allow both stable stacking and compact nesting of empty containers, reducing the space required for storage. The interior of the container can be configured with accessories such as dividers and front label strips, ideal for separating and identifying components. Ideal for workshops, departments and warehouses, this industrial furniture solution is designed to improve productivity and organisation, with attention to ergonomics, safety and long-term durability. Thanks to its modular design, it can be configured and expanded with dedicated accessories, adapting to different tasks and workspaces. The combination of sturdy materials and quality finishes ensures stable support, suitable for intensive work rates.
