Description
Overview:
The 48mm Serrated Jockey Wheel with 205x50mm Solid Wheel (MPN 800 0101) is a genuine Knott Avonride jockey assembly for trailers and towing set-ups using a serrated clamp. It features a 48mm (1.89 in) serrated outer tube that provides a positive, anti-slip engagement with a cast serrated clamp on the drawbar or A‐frame. The assembly is fitted with a 205 x 50mm (8.07 x 1.97 in) solid wheel and tyre to suit general transport and towing duties. The Knott data specifies a 200kg (440 lb) static/dynamic load rating for this model. Use with a 48mm cast serrated clamp as required; the serrations on the tube are designed to lock into the matching clamp profile for secure height adjustment. Knott lists service parts for this unit, including a replacement 205/50 wheel and tyre and a replacement spindle (578004), helping maintain the assembly in service over time. This model is distinct from the higher-capacity version that uses a 230 x 65mm wheel; check dimensions and ratings to match your trailer specification.
