Abstract: The present subject matter relates to systems, assemblies, and methods for connecting structural members together. A connector assembly includes an elongated track having a web, opposed edge portions that extend from a first surface of the web and that form a pair of slide channels, and one or more protrusions protruding from a second surface of the web opposing the first surface, the one or more protrusions being configured to connect to the first building member. A connecting member is adapted to connect to the second building member and includes a base that retains the connecting member to the channels but is movable within the channels along the track. In this configuration, when the connector assembly is connected between the first and second building members, the connecting member is movable in the track in response to relative movement between the first and second building members.
