Viking VK595 K25.2 EC Upright Fire Sprinkler: Superior Extended Coverage

The Viking VK595 K25.2 EC Upright Fire Sprinkler is a specialized suppression component engineered for commercial and industrial facilities requiring extensive water distribution. It installs directly onto wet pipe fire suppression systems to provide rapid fire control in high-pile storage areas, rack storage spaces, and large retail environments.
