Innovative locking latches and carriage of 3 at once saves time. Stacking option allows secured stacking of several organizers to save space and maintain organization. Removable dividers provide high customization for small parts and larger hand tools. Unique 90 degree angle in the main compartment design allows storage of hammers and angled tools or tape measurers comfortably together with the small parts in the other nearby compartments. Special lid structure - upper lid interlocking with dividers - prevents movement of small parts from one compartment to another.
