A turnbuckle, stretching screw or bottlescrew is a device for adjusting the tension or length of ropes, cables, tie rods, and other tensioning systems
One end has a right handed thread and the other end has a left handed thread. Tension can be adjusted by rotating the frame, which causes both eye bolts to be screwed in or out simultaneously, without twisting the eye bolts or attached cables
TOP TIP - When using turnbuckles / tensioners with steel wire rope we recommend at least double the size turnbuckle to the wire - eg. For 4mm wire rope use a 8mm turnbuckle
