SAIFPRO M12- 1pcs Galvanized Turnbuckle HOOK and EYE Heavy Duty Wire Rope Tension Hook 1  (Pack of 1)

These sturdy and durable devices are ideally used to create a high amount of tension on wire rope fixings and have an incredibly easy usability. One end is an eyelet to fix onto one point of your fitting and the hook end attaches onto what is needed to have tension applied to it. The thread on either end is set up to turn in opposite directions, so when you twist the turnbuckle in the middle, it will bring both threads together, thus pulling the wire and creating tension.
