NEW! COVID-19 Products
This 6" w x 4" h (15.2 x 10.2 cm) red sign with white lettering warns employees not to shut off the water supply to your automatic sprinkler system. The wording reads "THIS VALVE CONTROLS AUTOMATIC SPRINKLER SYSTEM AND MUST ALWAYS BE KEPT OPEN". The sign is silk-screened and then oven baked for added durability. These signs feature smooth, finished edges and four predrilled mounting holes.
Double jack chains for hanging sprinkler signs (item # 00450) are also available in convenient 2-packs.
