S Vent Security Grille  

This product is made of a 14-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 grille 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.

Ideal for holding cells, showers, psychiatric facilities and isolation units.
