Abstract: A post support socket, in which an end portion of a post is supportable by a wedge member, and the post support socket has an elongate body in which a longitudinal bore extends from an inlet end of the body. The body includes a peripheral wall which has an internal surface defining the bore. A slot defined by the peripheral wall extends longitudinally from the inlet end of the body and opens to the bore along its length. The peripheral wall has a laterally offset portion which bridges the slot over part of the length of the slot from the inlet end of the body. In use of the post support socket, a post having an end portion received in the bore can be secured by forcefully driving a wedge member longitudinally into the slot from the inlet end, between the offset portion and the post end portion.
