Zenith eye and eye turnbuckle is designed for tensioning cables, ropes and chains. Use to tension small shade sails, balustrading, catenary wire, guy wire, and for marine and general applications. It is galvanised to ensure rust resistance and extended outdoor use. For added security attach the eye with a d shackle or snap hook to your fixing point. should the turnbuckle become unhooked at any stage, the turnbuckle will be secure. One end of the Turnbuckle is threaded left-hand and the other threaded right-hand allowing the tension to be adjusted by rotating the frame.  This permits both the Terminals to be screwed in or out simultaneously without twisting the attached wire rope or fittings.
