thanks for the replies, guys ... first of all .... that was an oops of course ... should have been 4' x 8' x 4" thick.
Casters are not an option I want to pursue except asd a last resort ... it would limit the ability of the doors to fold perfectly flat together.
The bearing with half cages for conveyors sound exactly like what I'm thinking off ... drilling a hole in the bottom of the door would mean that I wouldn't have to disassemble them nor disturb the insulating ability (much).
Isn't thsi board grand?
too bad that common sense ain't
