The knot has several features which allow a rope to be shortened:
- It provides two loops, one at each end of the knot which can be used to pass another rope through
- The knot remains somewhat secure under tension; the coarser the rope the more secure it is (see Disadvantages, below)
- The knot falls apart easily when tension is removed
