Pendent Sprinkler in T-Bar Ceiling

Elements

About this detail

A pendent sprinkler head penetrates a T-bar suspended ceiling grid with a Viking E.3 escutcheon and a one-inch annular space, allowing a maximum recess of one-half inch. The branch line pipe is supported from an overhead structural I-beam using a three-eighths-inch beam clamp with a retaining strap. A three-eighths-inch threaded rod runs tight to the pipe to restrict upward movement, paired with a swivel ring and an Afcon swivel fitting. A second three-eighths-inch rod is installed at a forty-five to fifty-nine degree angle tight to the pipe for seismic restraint when the top of the pipe is more than six inches from the structural attachment.
