Hi, we're rebuilding a barn using solid green oak frames, with wooden sliding folding doors in the large (formerly) threshing barn doorways. A visitor mentioned using adjustable fixings for the door frames so that as the oak posts shrink or distort, the frame can be adjusted to remain square and true - clearly important for these elaborate door types.
Does anyone know of such a product? I've been searching without luck. Any help appreciated!! Thanks

Can the doors be mounted just in front of or just behind the oak frame?
