FSR's fire resistant floor boxes are purpose-built for installations where a floor penetration must maintain a UL fire rating. Our SmartFit poke-thru series (available in 4", 6", and 8" sizes) and FRK series floor box systems provide a fire-stopped path for power, data, and AV cabling up through concrete floors, without compromising the fire barrier.
Each poke through floor box kit includes a pre-engineered firestop assembly and ADA-compliant cover options, so you can match the box to your floor's fire rating and your room's power/data/AV requirements. Browse the options below to find the right fire rated poke-thru floor box for your project.
