Dual Magnetic Perimeter Seals
This door is equipped with a dual Magnetic door sealing system. It consists of a dual 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. Dual magnetic seals also offer a very high acoustical rating.
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.
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.
UL Fire Ratings
  In addition to acoustical testing, Overly has successfully tested this product to the latest UL fire test standards, including UL 10B (neutral pressure), UL10C/UBC 7-2 (positive pressure).
