I finished cutting, shaping and smoothing my rain fly tie out clips. Using the center hole, I tied a double fishermen’s knot and slipped the knot over the tree strap. This part will stay connected in the bag.
To test it I clipped it around the tree, and tightened the strap. From there it was the work of about 7 seconds to loop the tarp rope around the little hook and through the slot.
Done. No knots, no cord locks. For additional security, I looped it around the hook and then back through the slot the other way. I put a lot of force on the rope, and guess it would take a heck of a gale to rip the rope lose.
It came out just as easily.
I’m looking forward to trying these out under a time limit, to see how fast I can put my rain fly up, just in case.
