<p>The cage comprises a metal support framework and plastic panels that define trays for containing live-poultry. Horizontal floor panels of the trays are domed and slatted to prevent pooling of water. vertical fence panels are formed as open lattice boxes, combining good containment with good ventilation. Openable doors for the trays have a double-detent camming action, whereby the doors snap to open or snap to closed, whichever is closer. The cage is lifted on/off a truck with a fork lift.</p> |
