This plastic tackle box is a great storage unit for multiple items of similar sizes, such as window lock mechanisms.  Rather than require numerous openings in your sales kit, group the items into this convenient storage box, and only require one opening the kit, helping to conserve valuable space.   The cover latches closed so you don’t have to worry about your small components falling out.  The 6 compartments have internal dimensions of 3.9 x 1.2 x 1.3 inches each.  The external dimensions of the entire tackle box are 8.3 x 4.7 x 1.3 inches.
