The grille is made of 14/16-gauge stainless steel components, with the outer perimeter formed to raise the grille face 7/16" from the wall or ceiling. The edge of the grille is manufactured with a beveled slope. No open or unfinished edges exist. The horizontal louvers are attached to a mating frame and ‘locked in’ to prevent movement or removal. The vertical mullions are correspondingly ‘locked in’ place creating a penetration proof neck and throat of 1-7/16" depth. Coupling nuts are attached to the back of the face flange for use with threaded rods. A mating duct collar with nuts receive the threaded rod and are tightened accordingly.


SSV42 is installed into the wall (or ceiling) with the threaded rods attached. A mating duct collar with nuts receives the rod and is then tightened to insure a secure fit on both sides of the wall. Optional attachment mechanisms are available for both new and retrofit applications. Optional sleeve, locking angle and opposed blade dampers may be supplied, if required.
