The round turn and two half hitches is a secure, quick, and reliable way to fasten a line under load to a fixed object like a post or rail.
The round turn part of the knot is what takes the tension and bears the load. The two half hitches are what are used to lock the knot in place.
Step By Step:
- Take the working end of the rope and wrap it around the fixed object (post or railing) twice. (This acts as the round turn.)
- Pass the working end over the standing part of the line and through the loop formed.
- Pull tight.
- Do the same thing again.
- Pass the working side over the standing line and pull through the loop formed.
This creates the two half hitches that lock it in place.
