I installed an eye hook at the end of the Manson gauge opposite the micrometer. I put a short looped piece of rope through the ring for more control. Letting the block hang from the rope keeps everything vertical. I am not referring to the "ring" on the back of the micrometer. The micrometer hangs at the bottom of the barrel surface being measured and the "ring" on the micrometer is not used for anything.
