If you will send us a message we can give you a supply list, pictures, etc. on how to set things up for a cable run. We use one and think it is a great way of securing your Pit while also given them great freedom. As long as you have two good sturdy trees within 100 ft/ 33 meters of each other a cable run may be just what you are looking for.
Cable runs can also be superior to fences as many times a Pit can climb fences and trees near them and escape. Our Pit Camo climbs one of our trees to retrieve out kids tire swing.
Most everything can be found at your local hardware store. If not we will be happy to provide you with all the supplies needed. The biggest thing is cost. If it can be found locally shipping costs can be avoided as the chain and cable can be quite heavy to ship.
