Abstract: A nesting stabilizing device for limiting the rotation of accessories connecting to a hitch receiver with an outward end defining an opening. The outward end of the hitch receiver has a protruding ring about an outward surface. The nesting stabilizer has a base with a body portion receivable in the hitch receiver and also has a flanged collar for engaging the protruding ring on the hitch receiver in an interference fit, the flanged collar further being coupled with an accessory. In addition, the nesting stabilizer includes a fastener operatively connected with the base for urging the flanged collar against the outward end to cause the flanged collar to engage the protruding ring on the outward end. The nesting stabilizer connects the accessory to the hitch receiver upon engagement of the flanged collar with the protruding ring on the hitch receiver.

Abstract: A nesting stabilizing device for limiting the rotation of accessories connecting to a hitch receiver with an outward end defining an opening. The outward end of the hitch receiver has a protruding ring about the outward surface, fully encompassing the outward end. The nesting stabilizer has a base with a body portion receivable in the hitch receiver. The body portion is adapted for coupling with the hitch receiver to locate the base in a predetermined position thereon. The nesting stabilizer also has a flanged collar for engaging the protruding ring on the outward end of the hitch receiver in an interference fit upon engagement of the flanged collar with the protruding ring on the outward end, the flanged collar being coupled with the accessory. In addition, the nesting stabilizer includes a fastener operatively connected with the base for urging the flanged collar against the outward end to cause the flanged collar to engage the protruding ring on the outward end.
