Stretching chain-link fence is not very difficult, but the job can be done much better when you have a mechanical advantage. Since you are essentially trying to stretch metal, it can be near impossible to get all the kinks and ripples out by hand. When stretching the chain-link mesh, you will need a helper in order to unravel it and pull it taught.
Stretching Chain-Link Fencing
Roll out the chain-link mesh against the fence frame starting at one corner post. You will probably need an assistant to help with rolling it out. Slide a tension bar through the links at the end of the fencing. Allow the mesh to be able to slide along the ground.
Hold the tension bar in place along the pole and fasten to the pole with brace bands spaced 1 foot apart. Don't tighten the nuts completely until you are satisfied with the way the poles, mesh and tension bar look.
Stretch the mesh out between the corner posts with a pulling rod. Get the fence reasonably taught by hand wearing gardening gloves.
Hook one end of a come-along to a brace band on a corner post. Attach the other end to a pulling rod that is woven through the links of the chain-link fencing. Crank the come-along until all ripples are out and the mesh is completely taught.
Attach the stretched mesh to other corner post, slide the tension bar in the end and fasten with brace bands.
Finish the job by attaching the chain-link fencing to the top rail, using pliers to attach it with the galvanized wire.
