Tumble hitch

The tumble hitch is a "slip-free", quick-release hitch knot used for temporarily securing a rope such that it can be released easily to be completely free of the hitched-to object (instead of still being wrapped around it). The hitch might be able to be untied with a tug of the working end, even when under tension; but the workings depend upon materials and forces; note that in some cases, "under tension" will amount to simply being tied and the line itself giving significant tension by weight. The tumble hitch is tied in the bight.

Caveatpotentially unstable

Usually two locking turns (as in the pictures here) suffice for a knot secure enough for most purposes, but another could be added for further stability. The general knotting principles evident in this and the well-published "highwayman's hitch" can be implemented in a variety of ways. This knot was designed specifically to avoid the problem of the highwayman's hitch of putting the full force of loading upon the locking toggle ("slip") bight, which esp. in soft cordage can collapse that and pull it though the bight "frame" it had locked against! Hence,The Notable Knot Index recommends the tumble hitch as a more stable hitch than the highwayman's hitch.[1]


Tying

Tying sequence for one variant of the tumble hitch. Why isn't the specific, titled knot shown? A problem with this presented variant is that it puts in a nipping turn --like in a sheepshank-- which can hold the line hitched to the object even after the slip-bight/toggle has been pulled out!! Then, one must hope some vigorous shaking of the line will spill this nipping loop --potentially a difficult task.

  • Place bight 1 over a beam
  • Cross a bight near the working part over the standing part, under beam, up through bight 1
  • Pass the working part below and around the standing part and a bight up through bight 2
  • Tighten by pulling standing part and last bight
