Twin Axle wheel clamp

Hi all, I'm buying my first caravan, Bailey Pageant S7 Limousin twin axle and I need to buy wheel clamps. I think I could get Alko secure locks but as I need to get all the other extras, can't afford them. So, I need wheel clamps but being a twin axle I don't think every clamp will fit. Anyone can recommend one? As I say, can't afford the Alko, but would want to know what are my options for something else, maybe Bulldog or Milenco.

Thanks
