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.

Semi-Mortised Door Bottom

A semi-mortised automatic door bottom is always supplied with this assembly. This door bottom allows for a higher undercut. Automatic door bottoms are a good choice when flooring conditions are unknown, as they offer up to a 3/4" undercut.

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.
