Why is a turnbuckle used with pipe supports?

A turnbuckle provides two functions in a piping system. The first function would be to provide a minimum amount of adjustment for any field inconsistencies. The second function would be to provide the minimum amount of resistance when transferring load to the remainder of the support components.
