This is a redesigned version of my most recent mounting plate for Packout boxes. After sharing the design it was brought to my attention that the other version was only for the half width boxes. They could still be used for full width boxes but it wouldn't be as easy to align.

My new design incorporates connecting bars that lock two plates together. I have put the locking slots on both ends of the plates so you can connect as many of these together as you'd like. The tolerance is extremely tight so that way there is no movement or flexing between the two plates while mounting. I gently tapped them into place with a rubber mallet and they were very solid.

I have also included an updated locking tab as well for the full width boxes that is built into one of the connecting bars in case you need to make sure your box won't fall out of the mount.
