Hey guys,

May be you can help me out. I am putting up some osb as a shop ceiling.
The joists arnt on 4 ft or 8 ft centers. Is there some type of t shaped
filler material that could be pushed up between the butt joints of the
osb to help fill the gap? ( on the pieces that dont fall on a joist). If
there is such an animal, what is it called?

Just cut the sheets to fit the joist spacing.
