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.

Super "H" Door Bottom

Overly's super "H" door bottom is the only choice for unbeatable sound control. Always used in conjunction with our cam-lift hinges, this door bottom compresses tightly against the floor. We recommend smooth level sealing surfaces for this door bottom. Uneven or abrasive flooring may prematurely wear the door bottom. A smooth raised threshold is recommended when using this door bottom.
