Aluminum Streamline Collar Anode – 3-1/2″ Shaft
This 3-1/2″ Streamline Collar Shaft Anode is made with an aluminum alloy which is specially designed for cathodic protection use in either brackish or saltwater.
Being more economical than the zinc anode counterpart it lasts longer and is safer for the environment.
Streamline Collars are the best choice when it comes to propeller shaft protection and the oval shape minimizes turbulence and drag.
