Our Small Dog Tie Out with 830 Iron Snaps is constructed of 1/8" 7 x 19 cable PVC coated to 3/16". Our small cables are 7 x 19 stranding not 7 x 7 like most cables. More Strands = More Flexibility = Less Knots! #830 - 3/4" nickle plated iron snaps at each end makes this a strong cable for dogs and other small animals up to 75 lbs. in weight. The SRD20 is 20 ft. in length. Our coated cable sling is recommended for use with this product.
