An object redirection mechanism for a conveying system is provided. The object redirection mechanism is configured to redirect an object moved by the conveying system from a first direction to a second direction. The object redirection mechanism includes an arm tunnel positioned proximate an end of a conveyor configured for moving an object in the first direction. The arm tunnel includes an object stop having an object stopping portion defining at least a first side of the arm tunnel at least substantially parallel with the second direction and configured to engage an object moving in the first direction. The object stopping portion defines at least one finger aperture to enable at least one of the rotationally-retractable fingers to, when aligned with the at least one finger aperture, rotate between a retracted configuration and an extended configuration. A corresponding object conveying system and method of assembling an object stop are provided.
