RONSTAN 20ST ORBIT WINCH 1-SPEED

Ronstan’s Orbit Winches are the new benchmark in high performance alloy winches. With a combination of fresh design thinking and proven manufacturing expertise, Orbit Winches, weigh significantly less and offer lower line entry heights than any other winch in their class. Remarkably easy to service, they require no tools for disassembly or maintenance.

The fully machined aluminium drums feature the same Power Ribs that many will recognize from Andersen Stainless Steel Winches, well-known for their impressive line grip, smooth control, and minimal rope wear.

FEATURES:

Sprung self-tailing jaws to accept 6 - 10mm line.

Proven Andersen winch gearing configuration.

Power Rib ensures a controlled grip on the line at all times, whether trimming or easing. Minimal rope wear compared to more abrasive drum surface finishes.

No tools required for configuration and servicing.

Machined aluminium drum stronger and lighter than traditional cast aluminium drums.

Aluminium centre stem, lighter weight compared to bronze stems.

Low line entry due to gearing configuration geometry.
