Span Loop Knot

This is the an excellent and easy-to-tie mid-line loop. It is one of my two favorite loops for setting up a trucker's hitch (The other being a Bowline tied with the bight).

It is tied by rolling a loop forward and bringing a bite up and through from behind the loop. Then lower bite is pulled through the upper bite from behind.

It is easy to untie, even after holding a heavy load. It does not bind or slip.
