Amerex 5lb CO2 Fire Extinguisher B402
Value & Price Guide

Got this Amerex CO2 fire extinguisher for sale. It's the 5lb model, pretty standard for shops or garages. Looks like it's in good shape and comes with the manual and the wall bracket too. Good to have around just in case, especially for electrical or liquid fires since it doesnt leave a mess like the powder ones do. Gauge shows it's still in the green. Note that CO2 extinguishers usually dont have gauges, but this one is ready to go.
