2-26158 - Piranha Disc Anode Backing Pad 150mm

A disc anode backing pad for Piranha's 2-26058 and 2-26058A disc anodes. The anode backing pad is designed to stop the back of the anode from wasting away and potentially causing anode fixings to come loose. Anode backing pads also provide a barrier, helping to protect GRP hulls from alkalinity that can be produced as part of the cathodic protection process.
