Abstract

A seismic separation joint is provided for connecting end-to-end a first grid tee to a second grid tee. Each grid tee includes a central web, with a tongue or tab extending from the web. Preferably, an elongated slot extends from the web into the tongue/tab associated therewith, with the slots being aligned when the first grid tee is connected to the second grid tee. A fastener is received in a portion of the tongue/tab of at least one, and preferably both, of the grid tees distally of the slot in one grid tee and in the slot of the other grid tee.
