PM Product Of The Month: ProSet Systems<br>The Fire Guard Washer Box
ProSet has successfully fire-tested its new Fire Guard Washer Box, installed within a one- or two-hour rated gypsum wall using the same, ordinary installation methods used with nonrated plastic boxes - but without the need for stuffing with fire-resistant material or caulking.
The washing machine box has remained an area of vulnerability in firestopping, which has been largely addressed with the type of makeshift solutions referred to above. Even with this makeshift approach, a question remains about the ability of the box itself to resist fire. The ProSet Fire Guard Washer Box is constructed of sturdy, fire-rated plastic. All the plumber has to do is install it using the same, ordinary installation method, and all the inspector has to do to ensure the integrity of the fire-rated wall is see that the Fire Guard Washer Box was installed properly.
