Might have a few of these coming up lads. The branches I work at are undergoing their annual reviews for extinguishers, and I told the blokes that come out that if they are binning the old ones for whatever reason to call me and I will come grab them.
I scored 2 x 2kg dry chem with brackets last week free of charge. They are a bit big, but also free.
If I get anymore (Which I'm sure I will because my company LOVES wasting money on shit like this) I'll post em up, and whoever comes gets them first can have them. They are generally either slightly overcharged, or slightly uindercharged.
