The modular, mobile box set YT-09161 allows for practical tool storage and easy transport. The set consists of three elements that can also be purchased separately: the wheeled base box YT-09166, container YT-09168, and box YT-09169. It includes two managers for small parts with movable dividers and lids made of durable, flexible polycarbonate. Six removable containers in two sizes are suitable for hanging tools on the wall. Adjustable, removable dividers in the base box and the aluminum telescopic handle of the container, along with two covered rubber wheels, ensure convenient transport. The extended set is also durable, with polyamide closures, elastic seals for the cart and box, and strong latches protecting the contents from dust and water. The reinforced construction allows for the transport of heavy loads, and thanks to the side latches, it can be combined with other chests. The dimensions of the system manager kit are 585 x 425 x 810 mm.
