Tool storage is big business,  You can be like DeWALT/Milwaukee and make your own storage solutions or you can be like Bosch/Festool and re-market an existing brand. Metabo did the latter and followed in Festools footsteps by hooking up with Systainer.

It is called Metabo Metaloc and comes in a few varieties.  Not much is know about the system yet as we have seen an official USA press release.  The system looks like it can clamp to a Metabo dust collection unit and like Festool has a guide in the lid for tool placement.  We will keep you posted as more info trickles in.  The system is currently available only in the UK.
