Prop Shaft Bonding Brush Earthing strap (copper version)
This unique bonding mechanism has a copper plate (ideal for non rusting non transference and electrical conductivity) The anode brush provides a connection to the prop to the shaft, rudder shafts and others with ship bonding systems. This can also help majorly reducing radio frequency noises from other machinery. It has long wearing metallic graphite brush on phosphor bronze strap.
Main use is bonding for continuity, to link in with other anodic properties.
