A device which allows the linkage to be lengthened or shortened. A threaded hole is found on each end of the turnbuckle. The linkage which attaches to the turnbuckle can be screwed in or out on each end to create the necessary length. Usually a lock nut secures the turnbuckle in place. In some instances, the turnbuckle may have a threaded hole at one end and a threaded stud at the other.
