Abstract
Abstract A building corner assembly is provided for joining a pair of walls which lie in intersecting planes. Both walls terminate in arms which also lie in intersecting planes. The assembly also includes a post which has a pair of channels running along its length. The assembly further includes a corner lock which also has a pair of arms. One arm of the corner lock and the arm of one wall fit into one channel of the corner post, and the other arm of the corner lock and the arm of the other wall fit into the other channel of the corner post. The arms of the walls protrude toward the arms of the corner lock within their respective channels of the corner post and thereby enter into an interlocking relationship.
