Wait, I'm confused. Do the NPKC ones have some sort of cover? How can they stack if they don't?
Negative, no cover, I'm planning on working with them (MD - hopefully) to get some additional supports put in so that they are stackable.
This will be the first time they will run these so I'm thinking we can have a little bit of say (if it does run that is)
Check out the [IC] for a running list of 'features' that would be nice to have.
