GN202 GRATE NOZZLE PACKAGES

Grate Nozzle Packages include Grate Nozzle and two X-Frame supports with mounting hardware.

Model GN202 Grate Nozzles are designed to protect aircraft hangars and helipads. They are available with a 360°, 180°, or 90° discharge pattern and 26ʺ, 20ʺ and 555 mm widths to meet design requirements. The grate nozzles are low expansion foam discharge devices that deliver a uniform discharge pattern with a maximum spacing of 50ʹ x 25ʹ (15.2 m x 7.6 m). The nozzles are installed flush with the floor of the protection area within the trench drain. The companion trench drain grate is specially engineered to receive the grate nozzle  and serve as a cover for the drain trench.
