Vertical Adjustments for stand ups

Does anyone make or use vertical thrust adjustments for stand ups? If so has anyone used it or have comments on them? Thanks

Vertical Thrust adjustment?? Do you mean the abiliy to rotate the nozzle on the "Y" axis (up and down)? I am not sure of any that makes it go up, but hyd, drop nozzle setup will push it down. R&D makes them.
