So durable some trainers say they last almost forever! We proudly offer these articles for the serious trainer and handler who demands lasting service from a set of articles. In sets of twelve numbered articles: six metal and six leather. The metal articles are made with anodized aluminum ends and bars. The leather articles have extra-thick leather ends, and soft, durable leather covering the slotted aluminum bars. The leather is "tucked" into the slotted bar under pressure, thus eliminating troublesome stitching on the bars. Available in single, double and triple-bar styles.
