In a cleanroom, microscopic dust particles can lead to major problems. With a cleanroom cover plate on your concealed sprinkler heads, you can help avoid contamination without impacting the sprinkler's life-saving functionality.
How? By adding the Tyco Air & Dust Seal (Tyco Part # 56-908-1-001) to your Tyco RFII cover plates!
Tyco Air and Dust Seal is available in white and perfectly fits the RFII cover plate.
