A feeder floor protection system for a paving machine includes at least a first pair of wear plates covering a majority of a feeder floor. Each wear plate has at least two frame abutment features and at least two plate abutment features. Each plate abutment feature includes at least two non-contiguous lateral movement restriction surfaces offset from a centerline of the paving machine and at least one fore and aft movement restriction surface in a plane perpendicular to the centerline. The lateral movement restriction surfaces of a first plate of the pair of wear plates abut the lateral movement restriction surfaces of a second plate of the pair of wear plates. The fore and aft movement restriction surface of the first plate abuts the fore and aft movement restriction surface of the second plate.
