You don't know how much you need this until you buy it. I've used this for several things. I built an 8' tall storage shelving unit, which turned out to be more tipsy than I was expecting, so I ran a piece of cable from one end of my metal building man-cave from end to end, 8' high, crossed the 2x4 posts with it, and used a couple of fence staples to secure it to the shelving unit. It's rock solid. I used it to trellis my tomatoes (using drop-downs of jute twine., and I'll me using it on another trellis this week. Great quality too, and an unbelievable price. Buy it!
