Anti-Freeze System Sign | 6 in. x 2 in.

Anti-Freeze System Sign is an NFPA 13-compliant white powder-coated 18-gauge aluminum (.040 aluminum) sign designed to indicate the location of an antifreeze system in a fire sprinkler system. This 6 in. (152.4 mm) x 2 in. (50.8 mm) sign reads 'Anti-Freeze System' in red letters at least one inch (25.4 mm) in height.

Antifreeze systems require additional signage, including a detailed placard at the main valve and, for remote antifreeze systems, a placard indicating the number and location of remote systems supplied by the riser. This sign is drilled with four (4) holes for easy hanging.
