Turnbuckles Turnbuckles can be supplied with eye end fittings, hook end fittings, jaw end fittings stub end fittings, and any combination of these. Their rated loads depend upon the outside diameter of the threaded portion of the end fitting and on the type of end fitting. We seldom use turnbuckles for hoisting. Despite this they should be inspected frequently for cracks in the end fittings, especially at the neck of the shank, deformed end fittings, deformed and bent rods and bodies, cracks and bends around the internally threaded portion and signs of thread damage. A Few Tips: - Completely dismantle turnbuckles for inspection. - Thoroughly clean and inspect. - Soak turnbuckles in drums of diesel. - Store for use, preferably by hanging. - This is also an ideal opportunity to take photos of, or sketch, anything unusual. This may be of use in the future. - Make notes of what you found, where you found it and what, if anything, you did about it. - Renew any tags or stamps that identify the shackle. Refer to the Construction Safety Association of Ontario "Rigging Manual", Chapter 4, Rigging Hardware - Shackles.
