Viking Nozzle VK465 : Viking Mirage® Quick Response Concealed is a heat sensitive glass ball design nozzle designed for installation on concealed duct systems such as ceilings..., where the expectation is to want the appearance of a smooth ceiling. Low profile cap assembly offers vertical adjustment up to ½ (12.7 mm). The two-piece design allows installation with a sprinkler before the visor is installed. The push-up design on the platform, on the foundation of the concealed plate, allows the cover to be installed after the system has been tested and the ceiling finish has been applied. The cover assembly can be removed and reinstalled, allowing temporary removal of ceiling panels without removing the sprinkler system or removing the sprinklers.
