The Vink Beef Calving Aid is larger than the standard Vink model, and therefore requires a larger replacement Slide Bush.
The Vink Beef Replacement Slide Bush is designed specifically for the Vink Beef Calving Aid and as such will only fit the larger calving aid and can't be used on the standard model.
Please check if you have the standard or beef model before ordering spares.
50mm Slide Bush.
