You need a cable or wire tightened and held under tension, but you also want to see exactly where the thread sits. This M8 open-frame turnbuckle is 316-grade stainless steel, so it shrugs off salt air, rain, and the general roughness of outdoor Aussie use. Clevis-type pin retainers with split ring clips on both ends keep your cable from slipping out. Locknuts mean it stays put once you've set the tension. Adjusts from 180 mm to 270 mm. SWL is 550 kg, which is 25% of ultimate breaking load and generally limited by the thread holding
