What is the Amerex 24979?
Amerex 24979 is the replacement nameplate listed as item 32 in Amerex Parts Book 27277 Rev D, printed page 19, for model 491, the 300 lb wheeled ABC dry chemical extinguisher. Owner's Service Manual PN 05614 treats the nameplate as the extinguisher's service reference: the technician checks that it is securely fastened and legible, reads the date of manufacture from it, confirms the agent type against it and compares the extinguisher's weight with the figure it shows. The Parts Book notes that replacement nameplates do not include the UL or USCG listing. Amerex requires its own replacement parts to protect the UL listing and warranty.
