Wire guide, pulley for guiding the winch line (synthetic or steel). Made of steel and nitrided or hardened, chrome-plated with an external nickel coating. It is designed to greatly facilitate unwinding the line even in deep mud. The large opening (int. dia. 28mm) allows for easy pulling of thick lines even perpendicular to the vehicle. The galvanic coating reduces friction between the line and the pulley, making it much easier to unwind even when wet and full of sand, but on the other hand, the slippery surface protects the fibers of the line from damage.
The set also includes a sleeve that needs to be welded to the car and a securing ring (circlip).
