Chain link fence loop caps are installed on line posts or intermediate posts and used to secure top rail. Order one per line post. Simply slide over top of fence post; toprail or top tension wire slides in horizontally through hole. Offset side of fitting should point towards face of fence to help keep top rail flush with chain link fence fabric once stretched. Do not use these if barbwire is to be installed use barbarms instead. Use aluminum loop caps for residential or commercial jobs. Available to fit common sizes of posts and top rail.
