Buyer beware of what you get. Check the knots before buy any wire, loose knots will only mean troble down the road. Make sure it is a ture 12.5 G class 3 galvanized wire, not a 14g as some use and claim it to be a 12.5g. What is the weight of the wire? Stay Tuff is 408lbs per roll, what is the weight limit for climbing the wire (at what weight will the knots slip), how about the tension twists (are the like a small hump or does it have an actual bend in it). Call me if you need more. There are some wire companies out there at are crap and it will selling cheap wire off as good wire.
