a tray includes a floor and a pair of opposed side walls , each having a cutout , one of which is larger to form the dropside . a pair of bail members are pivotably and slidably secured to opposed end walls . the bail members are supported by the end walls at a plurality of selected heights . the bail member is arranged to provide structural support to the dropside of a similar tray stacked thereon . the stiffness of the support is increased by the design of the bail member , which has a support portion with an elongated cross section . the elongated cross section is maintained in a vertical orientation when the bail member is in any of the stacking positions . in this manner , the dropside can have a large cutout without deflecting substantially during use .
