Overview
The Rasco R1023 Model G is a 286°F upright fire sprinkler head engineered for automatic fire suppression in commercial and industrial facilities. Using a heat-activated fusible link assembly, this automatic fire sprinkler opens when ambient temperatures reach the sprinkler’s listed activation temperature, drenching the area surrounding a fire. Built with brass construction and a compact, low-profile design, this standard-response sprinkler delivers predictable coverage and reliable performance.
