Taskmaster head 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. Made of Marine Grade 316 Stainless Steel to withstand our harsh outdoor weather. Available in various sizes to suits your needs. Pair with a D shackle or snaphook to your fixing point for added security. 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 to allow both the Terminals to be screwed in or out simultaneously without twisting the attached wire rope or fittings.
