Abstract

A caulking system for applying and maintaining a position of caulk between a pipe and a floor to provide a firestop around the pipe includes a pair of collar portions. Each of the collar portions is positioned around the pipe and engages a peripheral edge in a hole in the floor to maintain a position of the pipe with respect to the hole. The collar portions extend around the pipe when the collar portions are coupled to each other. A caulk is engaged by the collar portions to keep the caulk positioned around the pipe and positioned between the pipe and the floor. The caulk inhibits passage of air, liquid or fire between the floor and the pipe.
