• Thread diameter, with larger threads able to carry higher loads.
  
• Take up is the total difference in length between the turnbuckle with the threads screwed all of the way in or out.
• Working load limit should be carefully matched to the application. This is likely to result in turnbuckles with threads of larger diameter than that of cables and eye bolts in the tensioning system.
• Material. turnbuckle have galvanized steel for most construction and industrial applications, as well as in stainless steel for offshore and ither critical applications.

A turnbuckle is a handy tool that makes lifting and rigging easier in the following ways: We use turnbuckles to increase or decrease tension on a load to make minor adjustments. A turnbuckle helps to accommodate a difference in sling length, ensuring equal load distribution.

How are turnbuckles measured? We designate turnbuckle body by the diameter of the rod threading into it and the length of the take-up inside the turnbuckle rather than the overall length. For example, a 1” x 6” turnbuckle body has an overall length of 8⅞”, but has an opening or “window” measuring 6”
