Four locks. That is all you need.
Every RunLock lock is made the same way: the rope goes through one of its own loops. Four variations cover everything from a tow hitch to a washing line. The animations play one step at a time and pause on each step; drag the slider to go back and forth, and press Slow if it goes too fast.
Running loop
The everyday lock. The rope runs through one of its own loops, so the noose tightens under load and opens again when you slack it off.

The lock for closed rings, hooks and chains under heavy load. It will not untie however hard you pull, and one pull on the free end releases it.

For tying down cargo and anything that must not creep. The rope goes over the load, around the anchor and locks on itself, with the built-in stretch keeping it tight.
