This sign reads "Hood #4". Dimensions: 4" x 2". This sign is used in commercial kitchens that have automatic extinguishing systems and are vital so employees and first responders can quickly identify specific hoods by number and identify hazard areas.
The sign is silk-screened and then oven baked for added durability. The signs have smooth finished edges and are completely backed with a double-sided adhesive tape for quick and easy installation.
