Ezelius adjustable eye hitch
The Ezelius adjustable eye hitch has an eye (loop) that is fixed while loaded, but that can be adjusted up and down the rope while unloaded. It can be used for example to put tension to tent lines or clothes-lines, to tye down aircraft and secure loads on vehicles. Ezelius adjustable eye hitch is a kind of friction hitch and adjustable eye (loop) hitch (knot).
The Ezelius adjustable eye hitch excels on slippery stiff polyamide (nylon) cords made for climbing purposes. While adjustable hitches like the adjustable Cawley hitch (adjustable grip hitch, number #1994 in The Ashley Book of Knots), the taut-line hitch (#1856, the eye version of rolling hitch #1734) and the midshipman's hitch (#1855, based upon rolling hitch #1735) just can not get any grip at all, the Ezelius adjustable eye hitch gets a firm grip. In this way the Ezelius eye is an important addition to knots for adjustable loops.
The Ezelius adjustable eye hitch was invented by Kasper Ezelius (born 1969, Örebro, Sweden) in 2018 while trying to find something better than modifierad tältlineknop on page 160 in a book (Geoffrey Budworth and Richard Hopkins, 2010, Vilken knop?, ISBN 978-91-7401-107-4). Modifierad tältlineknop was a knot that he did not find very good, so he experimented in creating a knot that had good performance as a locking knot for a loop. The idea was to go "backwards" on the rope in order to create a lever that forced the standing part to make a curve instead of going straight through the lose part.
Here, “eye” has been used instead of “loop” in the name of the invented knot. The reason was that a loop is a deprecated term for an eye according to A Glossary for Knot Tyers Ver. 1.9 2019 by Robert G Birch. However, it seems like most existing knots of this family are called loops. In order to fit in better with existing naming, Ezelius adjustable loop hitch would be more appropriate, and future usage will reveal what term will gain popularity.
Ezelius adjustable eye hitch is made by making two turns and stick the end under the turns as shown in the images below.
