Also called a “wind brace,” these are often about 4” by 5” in girth and about 36” to 42” long that connect between post and beams to give them support against wind and keep the building square. Braces were mortised in place, nearly always at a 45 degree angle. In earlier barns they are also trunneled at each end. In later barns they are not; therefore they only help in compression, not expansion of a joint. Being the smallest members of a barn frame, they were also the first to be sawn. Hand-hewn braces are often a sign of an early barn.
