Single "H" Perimeter Seals
This door is equipped with our patented single Super "H" door sealing system. It consists of a single compression type perimeter seal, along with a metal retainer and cover. Compression seals typically offer higher acoustical ratings The seal is composed of a felt/neoprene combination that forms a tight perimeter seal.
