How are turnbuckles measured?
A turnbuckle body is designated 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”. Common sizes available are 6”, 9”,12”, 18” and sometimes 24” take ups.
