[Broken Glass]

When I adjust the legs on my dock, I use a 5' pipe clamp. With a pipe clamp, you are able to rotate the jaws to any position that you need. I put the crank end of the pipe clamp on the top of the post, and then rotate the other end to go directly under the dock frame. This is done holding the pipe clamp tight against the post. You put a little pressure on it with the crank to hold it in place. Next loosen the bolts, and turn the crank until the frame is level. Re-tighten the bolts and release the clamp. The beauty of this method is the clamp actually pushes the post firmly down, as well as lifting the dock frame. Once the bolts are re-tightened nothing moves when the clamp is released.
