The new Technician Series Toolboxes from Lista International are larger and heavier than traditional toolboxes. Offered in single, double, and triple bank, as well as two-bay configurations, the toolboxes can require a heavier capacity wheel than previous models. Lista and Colson Caster Corporation partnered to provide a more heavy duty caster to carry the weight of these toolboxes. With a weight capacity of 7,200 lbs., the Technician Series Toolboxes offer a new locking system that locks the wheel rotation as well as the swivel, making the unit more stable when the lock is engaged.
