Nestable cart anti-reversing apparatus

Apparatus for preventing reverse insertion of a nestable cart, having a pair of wheels, each mounted to a support axle spaced along an axis, onto a nesting island which includes a track having an outwardly facing wall with a slot extending longitudinally in a desired direction of nesting formed therein, wherein, during cooperative nesting, a first of the wheels travels in the track while its axle rides along the slot;

• said apparatus comprising a tab extending laterally from the cart proximate a second of the wheels and being positioned relative to the second wheel such that, if nesting of the cart with the second wheel traveling in the track is attempted, said tab will engage the track at an entry end thereof at a location spaced from the entrance to the slot.
