measuring lifelines ?

[Matthew Sebring]

I've always measured from center of pin at turnbuckle (or what-have-you) to the bearing surface of the gate eye and then for the gate itself from bearing surface of one gate eye to the bearing surface of the gate eye or bail on the other side. Then when I make make it up I can clamp those gate eyes down on my table and then make up the gate assembly between them. In terms of a standard way to do it, I doubt there is one.
