Spreader bracket to fit Motofish swivel sheels to the front of Motofish, MAP and Matrix trolleys.
Fix our swivel wheels bases using the outer holes. Fix the leg brackets supplied in the slots (designed to create wiggle room for different width trolleys).
Then simply insert the assembled unit into the trolley's existing front leg mounts.
Note: Without the spreader bar, swivels wheels clash when mounted on their own to the narrow fronts of trolleys.
