Festool 577816 Systainer³ Rack SYS3-RK/6 M 337-Set

There are two approaches to organization when it comes to small parts, like WAGO connectors, wire nuts, etc.The first is to use an organizer box with lots of little containers to hold everything you might need.The second is to use smaller containers to hold each subset, and this rack works well for the second.For example, if you do LV you could use one S box to hold WAGOs, wire nuts and other electrical connectors, another to hold RJ-45 and various Ethernet connectors, and so on.With the rack you only need take the containers that have the parts you need into the job with you, rather than having to carry an Organizer with everything you might need.Again, philosophical difference based upon how you prefer to work.The build quality of the small Systainers is excellent, as you'd expect, and the rack locking mechanism works really well.Highly recommended if you work in the "second" way.

Not a must-have but it's a very good solution to keeping small items organized.
