Heckler Lectern Casters add 75 mm locking wheels to any Heckler Lectern, converting a fixed-position lectern into a mobile platform. Each caster uses a chrome steel radial ball bearing for smooth, quiet rolling across hard floors, carpet, and transition strips. The total-lock mechanism secures both wheel rotation and caster swivel simultaneously — lock the lectern in position during presentations, then release and reposition between sessions. M8 threaded stems install directly into the Lectern base without adapters or additional hardware.
