I have been waiting on these to be in stock forever. Apparently. I didn’t get an email when they came back in stock.Carabiners would work as block and tackle or get a couple of these small pulleys: https://www.wiserprecision.com/products/pynch-pulley
Paracord as stated above works in the pulleys.
I’m glad I saw your post. I just ordered a half dozen.
