Three Flouts are sequenced by a Cuebox sequencer. The Flouts are set up for 22" drawdown. This is a good example of built on shims. The shims are attached to the Flouts and keep them 4" off the floor of the chamber. The set of this Cuebox would be a total of the shim height (4"), plus the height of the Flout bodies (4"), plus the drawdown (22") for a total of 30".
