DO NOT use a wrench that is not specifically defined in the manufacturer datasheet as compatible with a sprinkler head during installation. This may damage the fire sprinkler and can cause a delay or error in activation when needed. Cabinet wrenches are made of plastic and are generally not suitable for use as a primary installation wrench. For specific installation instructions, refer to the manufacturer datasheet for the specific sprinkler head. See below for list of compatible sprinkler heads.
This wrench replaces to Viking™ 24339 cabinet wrench. Ratchet not included.
Why do building owners need spare fire sprinkler wrenches?
Commercial sprinkler systems installed in accordance with NFPA 13 require anywhere between 6 and 24 spare sprinkler heads to be stored in a cabinet on-site. NFPA 13-compliant cabinets also require a supply of wrenches used to remove and replace existing heads. The Viking™ 23143 light-duty cabinet wrench fulfills this requirement for select residential concealed pendent sprinklers.
