I have just gotten in Line Locks (not to be confused with Line Locs3) for tie outs. I have Black, White, and Glow in the Dark.
These are really good. Hold well and can be adjusted with one hand. I set it up oposite to the picture. I put the loop on the tarp D-ring and use a Marlin Spike Hitch for the stake.
Don't let life get in the way of living.
I love my glow in the dark line locks - means I can see my way home in the middle of the night when I wander out to find a bush.
I use mine permanently attached by a loop of shock cord and then tech-line with a loop spliced in at the stake end.
+1 on glow in the dark, they have saved me and my tarp on several night mission returns.
Dutch, you might say what size of cordage that they can be used for
