Chain-link fencing is arguably the fastest and most durable fencing solution available on the market. Each chain link fence can be broken down into three main parts: posts, fittings, and fabric. Posts are used as the framework that supports the chain link, allowing it to stand upright. Fittings are the hardware that is used to mount the chain link to each end post and line post. The chain link fabric is stretched between each end post and creates a high security barrier.
