Extra rope on fly rail

Footer - In my learnings they are safe to use. When I was first shown one it was to indicate to others that the line was at trim and should not be moved (an electric for example), but I believe that they can also be used to help secure a line that is slightly out of weight. NOT a lock by any means but a way to assist when loading a back drop.
Derek - 1. Not sure....
2. The 3rd Electric is B. bellow its designated trim
The knot looks like a variation of a round and two halves. Round Turn and Two Half Hitches

I'm just taking a shot in the dark here but this is what I would use them for, I would use them to tie around the brake or something to let everyone else know that there is, has been or will be some form of weight change that needs to be adjusted. For example when you add or remove lights from an electric.
I've heard stories of what happens when someone doesn't know an electric is out of weight and goes and takes the brake off and I've seen what it can do to your hands if you hold on, it's not a pretty sight.
Again just a guess. That's my two cents on it.
1.a: The knot looks like 2-half-hitches with the free end secured with a piece of spike tape.
edit: i was wrong...its a girth hitch

1a. Two Half hitches is the knot (try to make it harder nex time...)
1b. ? someone was knot paying attention... (pun intended)
2. Third electric is AT trim
There are many different ways, I will throw out that you should never spike to the top of the handle because the handle is down when you are moving the piece therefor you have no reference.
So, people of CB, how does YOUR house mark trims?
Also, if one was to use those ropes to secure an out of weight lineset, how much weight could it safely hold?
1a. They are larks head knots.
1b. I believe 19 is a left handed larks head.
Larks head knots are also called cow hitches and girth hitches.
2). My guess would be above, but it could also be below, or coinciding, depending on what level rail we are at, and what identification method the venue uses.
This line would/should be used to tie a safety hitch, given its length, I would assume in this case they would use a stopper hitch.
How thick is the rope, how old is it, and what is its composition. Also, how old is it?
I'm not really interested in breaking strength, more asking how would you attach it to the purchase line and how much weight would you put on it?
It's 1/2 inch, cotton sash cord, commonly used to rig travelers.
1) What are the advantages of using this type of rope for the pictured application?
2) What are the disadvantages?
1) It will allow for a better grip due to its smaller diameter. All the force is on this line instead of the tension block and the guides. A stopper hitch (as well as a prusik knot) can be slipped to remove the load from the deck in a controlled manner.
2) Cotton is not as strong as other materials, it is the weakest natural fiber. It has very bad shock absorption. If one of the knots is improperly tied it could result in a runaway.
