to picker beam flanges 33 a and 33 b picker beam spacer pads 36 can provide increased friction between picker beam flanges 33 a and 33 b and stack beam flanges 22 a and 22 b making stack beam 20 less likely to dislodge from picker beam 31 in the exemplary embodiment picker beam spacer pads 36 are a high friction material such as a rubberized material attached to picker beam flanges 33 a and 33 b with an adhesive or fastened with mechanical fasteners in other embodiments picker beam spacer pads 36 may be texturized regions of picker beam flanges 33 a and 33 b a proximal end of picker rod 37 connects to picker beam 31 via picker connector 38 because a downstream side of picker beam 31 engages an upstream side or sides of stack beams 20 picker rod 37 must connect to an upstream side of picker beam 31 picker rod 37 may connect through picker beam flanges 33 a and or 33 b or along picker beam web 34 a distal end of picker rod 37 extends above the maximum height of the plurality of stacker beams 20 allowing application of a lifting force to picker mechanism 30 in one embodiment a mechanical device operatively attached to the distal end of picker rod 37 provides the lifting force when actuated in another embodiment the lifting force is manual fig2 is a flowchart illustrating an exemplary embodiment of a method 200 for opening an incrementally adjustable fluid control system 100 in step 202 method.
