A string of magnets added long the back of this pair of 8in/20cm long parts bags adds a surprising amount of functionality. Not only do the magnets enable the pair to secure to one another, each magnetized pouch can attach to the ferrous mounting point integrated in the TP-XXL, TP-XD and TP-XL. When on the go the pouches can secure themselves to a substructure keeping small parts, test leads or precision tools within hands reach. The magnets can also temporarily keep the screws from a removed shroud in place.
