Amerex B260 Wet Chemical Fire Extinguisher 6L. I have 3 commercial fire extinguishers for sale. These units were removed from businesses prior to remodels and demolition. They retail at twice to three times the prices below. They have all been inspected by local fire marshals and are fully charged. This is a great deal for any property manager or any business owner needing several fire extinguishers to pass code inspection. 2 - Amerex B260 - 6L or 22lbs.
