Fire-Rated Washing Machine Outlet Box with Arrestor

HoldRite fire-rated washing machine outlet boxes with built-in water hammer arrestors combine the functionality of a fire-rated outlet box with the added benefit of preventing water hammer. Designed for residential laundry spaces, this outlet box ensures a smooth and quiet operation of the washing machine. In the event of a fire, these boxes act as a barrier, delaying the fire's progression and limiting its impact. This helps protect the surrounding areas, minimize property damage, and provide valuable time for occupants to evacuate safely. By using fire-rated outlet boxes, homeowners and building occupants can have added peace of mind knowing that an extra layer of protection is in place to mitigate the risks associated with fire hazards in laundry spaces.
