20mm Extreme High Load – The XHL range has been designed to deal with extremely high loads without compromising on low-load dynamic performance.

By combining the Allen patented dynamic bearing technology with a plain bearing peek washer we have created a bearing technology that has extreme dynamic performance even after being subject to static loads of up to 900Kg. Coupled with CNC machined aluminium side cheeks and a precision turned stainless-steel sheave the range is perfect for use in vang cascades or halyard turning points where loads can be extremely high.
