Ashlar post
An ashlar, ashlar post or ashlar piece is a traditional timber framing term. It describes a short timber upright which runs between the rafter and the inner face of the wall of a masonry building, it completes a small triangle at the end of a roof truss (at the end of each purlin). These small timber pieces are crucial in allowing the truss to sit completely on a masonry wall and can be seen in many traditional timber roof structures sitting on masonry or brick walls, wherw the tie beam is raised higher than the middle of the rafters.
