Why W.O. diagonals do not feature an Adjustable alignment system?

• Having an adjustable alignment system is an admission that the diagonal can go out of collimation due to poor mechanical construction.

• Thanks to the patented design of WO diagonals, you will always have a perfect aligned product from day one onwards, it’s as simple as that.
