Fasteners are used to secure the cable and tighten the straining wire to prevent sagging or drooping.
Straining wire is attached to the anchors using ferrules. Ferrules are used at the first corner attachment and later at the turnbuckle. Run two ferrules through the end of the cable. Then loop the cable through the first corner attachment and back through the ferrules. Crimp the ferrules twice to lock the cable into place with a ratchet crimp tool.
Run cable through all intermediate attachments and finally though the turnbuckle at the end of the cable run. Turnbuckles are used to tighten your straining wire. Make sure the turnbuckle at the end of the run is fully open before securing and tightening the cable
