Adjustable Gripping Hitch

I came across this effective griping hitch several years ago.

I don't know if it has a name.

When the standing end is held and the loop is pulled the knot locks tightly in place

If you hold the knot it can be slid along the standing end.

I use to adjust tension in guy lines, clothes lines and tarpaulin tie downs

Wrap the working end WE around the standing end.

Bight one.

Go around a second time.

Bight two.

And a third.

Bight three.

Bring WE over, under.

Bring WE through bights one and two.

The knot is complete

Tighten.
