FireStop™ Box Guard

FSBG Series

NSi FireStop™ Box Guards are one component fire rated pads made of highly intumescent firestop material for use in -electrical boxes. They are inserted in the box and adhere to the inside back wall. NSi FireStop™ Box Guards are easy to install and very cost effective. When exposed to fire they expand, forming a char that will seal off the opening, prevent the spread of fire and limit the temperature rise on the unexposed surfaces. When used as directed, the horizontal separation between outlet boxes on opposite sides of the wall may be less than 24 inches, provided that the boxes are not back-to-back. FireStop? Box Guards are classified by UL under Wall Opening Protective Material as found in the Fire Resistance Directory. Available in two sizes to suit single and double boxes. STC Rating 55.
