About this detail

A compression post assembly extends from the bottom of a concrete slab structure to a suspended acoustical ceiling grid. The compression post consists of a telescoping tube arrangement utilizing electrical metallic tubing members secured together with self-tapping screws and a machine bolt. The slotted end of the tube fits directly over the structural main tee of the ceiling grid. Four twelve-gauge splay wires provide lateral bracing in the plane of each ceiling runner, secured within two inches of the tee intersection. A compression post schedule specifies member sizes and lengths for different ceiling heights.
