Electrical connector storage....

I use these for a lot of stuff. Weatherpack, cable ends.

Some of the other connectors I use this set up.

I like that they are portable. Not bolted to a wall. I use a sharpie and write what is in each container lid edge and they stack real nice on a shelf. Need weatherpack, Packard 56, Std crimps, Fuseseasy to see and grab the one you need.
