Since no base is provided how is the 3/8 plywood attached to the frame? Is there holes / or a lip in the frame to secure the plywood to the base?

The plywood sits on a lip, but is contained within the 4 corners of the drop down supports. And, if the plywood is cut to 4x4, it is impossible for it to fall out, much less move at all. I have three 4x8 foot sections in my garage.... fantastic!

When installing the two 4x4 units to make 4x8, do you just use 6 ceiling supports?

I doubled up the verticle supports in the center sections when installed as one 4x8 shelf. (You need to in order to connect the horizontal bars that support the plywood). I doubled the rafter hangers in the center too, extra support and the other option is throw them away or have them lay around unused.

How thick is the base +plywood? my garage door allows for 16" of space above the door and im trying to determine how much space i will have leftover.

Base height is 3". If you use our recommended 3/8" plywood the bottom support total height base + plywood is 3.375 inches. Hope this helps.

Can the top horizontal bars that connect to the ceiling run the other direction

Yes they can. I’m assuming you’re asking because there isn’t a beam parallel to one of the sides in your installation location. In that case you would turn the mounting bar 90 degrees to attach and span across two beams. Hope that helps
