15mm Reliable RFC49 Residential Concealed 74C SSP Sprinkler.

Model RFC Residential Concealed Sprinklers are flat cover plate, pendent sprinklers with a 74C temperature rated fusible-link operated element. Residential sprinklers differ from standard sprinklers primarily in their response time and distribution patterns, which are generally higher and contain a finer droplet size than standard sprinkler patterns. The RFC cover plate pushes onto the sprinkler.
