I assume you are wondering at what angle to the mast. That is not all that important. They should never be below 90 degrees to the mast. The rule of thumb is, the spreader should bisect the shroud. In other words the angle of the shroud above and below the spreader should be the same. This usually but not always has the spreader tips slightly above horizontal
