You could use a couple of hand stretchers to stretch chain link, but where’s the fun in that? Instead hook this A-frame fence stretcher from American Fence & Supply Co. onto the tension bar and then pull the stretcher with a Come-A-Long.
Use this 30″ stretcher for 4′ chain link fence. It runs $30, but unfortunately you’ll pay $25 in shipping charges. If you’re a Texan you also get hit with tax too.
