The cases themselves. Heights run 137, 187, 237, 337 and 437 in M and L footprints, so the depth matches what goes in rather than everything living in one size. The T-LOC catch opens, closes and connects in one turn, and every case links to the others and to earlier generations. ToolBoxes add an open upper tray for the things you reach for constantly. Sortainers replace the box with drawers for fixings. Organisers hold small parts in removable containers. Pre-filled sets cover drill bits, auger bits, ratchets, dowels and terminals — a case that arrives sorted rather than one you sort yourself.
