1st Chair thrones offer the best of both worlds: the exact height adjustment of threaded rod thrones and the fast adjustment of T-bolt systems.
Loosen the bolt (A) and raise the threaded rod to your desired height (you don't have to get the exact height at this point).
Screw the height lock (B) to the top of the nylon bushing.
If a minor adjustment is necessary, simply turn the height lock or rotate the seat.
Tighten the bolt (A) firmly.
