system. It consists of a single compression type perimeter seal, along with a

ratings The seal is composed of a felt/neoprene combination that forms a tight

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.

UL10C/UBC 7-2 (positive pressure).
