At last, a sturdy, Hi-Temp PVC, Fire-Rated Utility Box designed for appliances such as washing machines, icemakers, etc. No more jury-rigging, stuffing with fire-resistant material and caulking to satisfy building code requirements. You can now make sure that the rating of a fire-rated wall is not reduced when installing a washing machine box opening.
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 non-rated plastic boxes, but without the need for stuffing with fire-resistant material or caulking.
