The grille is made of 12-gauge steel (stainless steel if used in humid areas) with the outer perimeter stamped to raise the grill face 5/16” from the wall or ceiling. The edge of the grill is manufactured with a beveled slope. The portion of the edge of the grille that will contact the wall or ceiling upon installation is machined to a flatness of ±0.003”. No open or unfinished edges exist. The horizontal louvers are attached to a uniweld 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.
SV2 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.
