For complete freedom of movement when lifting, it's best to go with a hoist ring. These metric hoist rings swivel a full 360º and pivot 180º while under load. Unlike cheaper, more generic swivels and eye bolts, these continue to move during your lift to avoid binding and incorrect load angles. And the rated load doesn't change, all the way from 0 - 90º. Black oxide finish for corrosion resistance. Safety factor of 5:1.
