Joiners availability

Any estimate of when 7U case joiners will be available again?

I sold off my Palettes to consolidate my system, decided to pass on the new Befaco cases since I like IJ and already had a Performance (and the Befacos couldn’t be had anyway), bought a second Performance… then couldn’t connect it to the first. And I just don’t have space to have them side by side at the moment.

For want of a nail… or in this case another relatively simple piece of metal…
