A friction hitch is a kind of knot used to attach one rope to another in a way that is easily adjusted. These knots are commonly used in climbing as part of Single Rope Technique, Doubled Rope Technique and as 'ratchets' to capture progress on a moving rope, most typically in a mechanical advantage system such as a Z-drag. These hitches are a simple and cheap alternative to mechanical ascenders.

Famous quotes containing the words friction and/or hitch:
“We have got onto slippery ice where there is no friction and so in a certain sense the conditions are ideal, but also, just because of that, we are unable to walk. We want to walk so we need friction. Back to the rough ground!”
—Ludwig Wittgenstein (1889–1951)
“If we should swap a good library for a second-rate stump speech and not ask for boot, it would be thoroughly in tune with our hearts. For deep within each of us lies politics. It is our football, baseball, and tennis rolled into one. We enjoy it; we will hitch up and drive for miles in order to hear and applaud the vitriolic phrases of a candidate we have already reckoned we’ll vote against.”
—Federal Writers’ Project Of The Wor, U.S. public relief program (1935-1943)
