Isolated Edge Construction
This door uses an Isolated Edge construction, which separates the two outer door skins from each other. A strip of neoprene is installed between the two door skins, reducing the amount of sound transmission through the actual steel faces. The seal is notched between the hinge and lock cutouts and does not interfere with hardware cuts.
Single Magnetic Perimeter Seals

This door is equipped with a single Magnetic door sealing system.  It consists of a single magnetic perimeter seal. Magnetic seals allow the use of a wide range of electrical hardware, such as electric locks and strikes.  Due to their zero preload against the door leaf, the sensitive electronics are not compromised.

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.
