Abstract: A wire reel carrier for use in stringing barbed wire for fencing is designed for attachment to a horizontal cargo rack of an all terrain vehicle. The wire reel carrier includes a pair of spaced frame rails secured by a plurality of clamps to the cargo rack. An elongated rod dimensioned for insertion through the hollow core of a wire roll extends transversely between the frame rails. A pair of retaining plates, each secured by a frictional collar, maintain the wire roll in correct orientation on the transverse rod. A pair of safety latches secure opposite ends of the rod to respective frame rails and include a safety mechanism for releasing the rod from the frame rails upon exertion of an excess force on the rod by a wire being strung from a roll supported on the rod. This prevents the occurrence of severe accidents and possible injury to the ATV operator upon tangling of the wire.
