A building construction assembly including a first elongated structural member having a longitudinally disposed keyway having a base wall and a pair of sidewalls projecting from the base wall. Means providing an elongated restricted throat keyway opening. A second elongated structural member having a longitudinal axis disposed generally transversely with respect to the longitudinal axis of the first elongated structural member. The second elongated structural member having a locking channel having a bottom wall, a front wall and a rear wall. The second elongated structural member disposed with its locking channel in aligned relationship with respect to an end opening of the keyway. A locking key having a first portion extending into the keyway and a second portion extending into and in engagement with the locking channel. Means resisting undesired movement of the key into the keyway sufficiently far to permit removal of the second key portion from the locking channel. A condensate gutter element may be secured within the locking channel.
