A tray section is constructed of longitudinal and transverse wire members (90, 92). The tray sections (80, 82) may be configured or joined by interlocking clips (98), each of which features two pairs of opposing tabs (104, 108) separated by a pair of opposing notches (112, 114). The opposing notches (112, 114) feature an arcuate portion (116, 118) and each is sized to receive a single longitudinal wire member (90). Each interlocking clip (98) also features a back portion (120) that is integral with opposing tabs (104, 108) and notches (112, 114). The back portion (120) and opposing tabs (104, 108) are sized so that they surround a pair of adjacent transverse wire members (94, 96) when the opposing tabs (104, 108) are crimped. A crimping tool (130) is used to install the interlocking clips (98) and features pivotally connected opposing jaw portions (136, 138) with arcuate indentations (142, 144). The arcuate indentations (142, 144) are sized to cooperatively surround the back (120) and opposing tabs (104, 108) of the interlocking clip (98) with the pair of adjacent transverse wire members (94, 96) received therein. Wire mesh floor pans (160) that do not obstruct air flow may be used to support the tray sections (80, 82). |
