Brackets for roof mounted airconditioning units. Instead of mounting an inverter on a piece of two by four through roofing into rafters or purlins, our selection of roof brackets for air conditioning will last longer, look better, and save you time. The arms are adjustable to suit the pitch of the roof. The manufacturer’s recommendation is suitable down to seven degrees. The air conditioning roof brackets are electrogalvanised steel and support up to 140kg.
