Taut-line hitch

Use: The Taut-Line Hitch is an adjustable loop knot for use on lines under tension. It is useful when the length of a line will need to be periodically adjusted in order to maintain tension. It is made by tying a Rolling hitch around the standing part after passing around an anchor object. Tension is maintained by sliding the hitch to adjust size of the loop, thus changing the effective length of the standing part without retying the knot. When under tension, however, the knot will grip the cord and will be difficult to cause to slip. It is typically used for securing tent lines in outdoor activities involving camping, by arborists when climbing trees, for creating adjustable moorings in tidal areas, and to secure loads on vehicles. A versatile knot, the Taut-line hitch was even used by astronauts during STS-82, the second Space Shuttle mission to repair the Hubble Space Telescope. How to tie: Pass the working end around the anchor object. Bring it back along side of the standing part and make a half-hitch around the standing part. Continue with another wrap inside the loop, effectively making a round turn around the standing part. Complete with a half-hitch outside the loop, made in the same direction as the first two wraps, as for a clove hitch. Dress by snugging the hitch firmly around the standing part. Load slowly and adjust as necessary.
