Turnbuckles tighten and secure the cables and provide the necessary tension for a clean look. For short, straight runs (runs under 20'). Mount to wall or ceiling. When ceiling mounted, cables drop 1" from ceiling. Pair. If mounting to metal, order isolating version.
All turnbuckles include mounting hardware for drywall. Special hardware is available for brick, cement, or plaster surfaces(sold separately). For all runs of over twenty feet, turnbuckles should be reinforced with wood blocking behind the wall.
