Comer branches are used to connect to branch runs of drainage coming from different directions into a main soil stack. As the name suggests, they are most commonly found in the corner of a room. The angle of this 88 degree corner branch creates a 2 degree fall that promotes self-cleansing. The long tail on this branch adds flexibility with the positioning of the connection to the pipe below. As Halifax pipes and fittings have no sockets, couplers are required to connect this branch to a pipe. A full dimensional drawing of this product can be found in the  Halifax technical catalogue.
