All ropes are made of top quality marine braid. They are salt and sun resistant and washable. There is a loop on one end for you to add your choice of snap and a leather popper on the other end. Choose your length depending on the size of your round pen ie. 50′ round pen, order 26′ or 60′ round pen, order 32′. Horses like to use the rail without pulling on the rope. Choose the weight depending on the size and lightness of your horse, ie. 2 x 18′ lite lines for 2 rein driving a 12 to 14 hand pony, or 32′ regular weight for large draft horse in a 60′ round pen. Your name or your horse’s name can be stamped on the leather popper.
