This extra sturdy metal wall bracket is suited for our C02- fire extinguishers of 2kg or for all other fire extinguishers with a suspension through the eye on the neck of the fire extinguisher.
A metal wall bracket offers more support than the standard wall hook that is delivered with it. This is mostly important for less sturdy or uneven walls (like gyproc) because the wall bracket is better at spreading the weight over a larger surface.
