Add extra length to a Roman or H-style harness girth. Clips into the harness girth buckle. 4" is the standard length, but they can be ordered in longer lenghts if needed. Available in all 1/2", 3/4", and 1" patterns and solids. Please note: Current buckles are not compatible with older versions of buckles. Care should be taken to identify the buckle when ordering these for older harnesses. We can email a PDF that identifies the available types of buckles.
