You can use galvanized or stainless steel material with bare or coated cable. Post to post or ground anchor just figure the length of the run (be sure to include turnbacks for end fittings) and how you want to fasten to your points (eye bolts, turnbuckles thimble eyes) and place your order. Quality Chain and Cable can supply the material but we are not designers or fabricators. If you know what you need this is the place for quality materials at wholesale prices, if you need to know how to do it a pet store might be a better option
