For me the quickest, and best adjusting length limiter is laying in a piece of T Track into the fence, and use a double locking block to be your stop. That way it takes you releasing it, or an act of God to make it budge. A single point can turn, or come loose easier. attached at 2 points, and it stays where ya put it.
Stealing Jonathans thunder here, but I ain't walking back to the shop in 4 degrees with the wind at 20 MPH. As crafty as you are Jim, I know you can roll your own. :-)
