These new old stock Stack-On steel toolboxes were discovered in a surplus warehouse of a company in Rhode Island that assembled kits for the government. They were manufactured in the USA sometime in the 1980s or 1990s. The toolboxes boast solid steel construction with a powder coat finish and zinc hardware. Additionally, they feature an internal tray, and the compartment below the tray is 4” tall. The overall size of each toolbox is 16" x 7-3/8" x 7-1/4". Please note that the stock is limited, and once these are sold, there will be no more available.
