Suitable for vessels with a 20mm diameter shaft, this zinc shaft collar anode is 10mm thinner than MG Duff's standard ZSC20 Zinc Shaft Collar Anode. With its thin moulded section, the zinc shaft anode is perfect for boats with limited clearance between the propeller and bracket, allowing boat owners with minimal shaft clearance to protect their valuable propeller and shaft.
The ZSCT is one of the thinnest shaft anodes on the market and is manufactured by MG Duff, whom's zinc anodes are renowned for their superior quality and high zinc content.
