Installation Advice

Before fitting the swageless ball end tensioner we recommend installing the fixed ball end fitting on to the opposite end of your wire rope, and the mounting sockets on to the posts (Fixed ball end and mounting sockets available separately). This will enable you to calculate the length of wire rope required before cutting.
