Fire Rated Drains

ProSet provides a complete line of Government spec fire-rated drains. These drains can connect to plastic or cast iron pipe through above-ground floors or ground-floor concrete slabs. ProSet also has a low-profile drain which will connect to plastic in a metal deck or in a wood floor. Photographs of the drains, with drawings (which show the Trap Guard installed) are shown, below.

All of these fire-rated drains are suitable for use with ProSet’s Trap Guard Drain System for flexibility in the use and placement of drains.
