Also called a collar beam or stress beam; joins two posts together near their tops. In an English barn they join the queen posts supporting the purlin plates. The invention of the hay track very often led farmers to cut the collar ties out of their barns because they interfered with the travel of the hay hook. This is ultimately disastrous to a barn frame, allowing the purlin plates to start slipping in under the roof. This situation led to the invention of the canted queen post which did not need collar ties to spread the queen posts.
