Tighten slowly by pulling on the loop and the

Overhand Loop

A SIMPLE AND SECURE FIXED LOOP FOR USE WITH

STRING OR LIGHT CORD

Almost as simple as the basic overhand knot (see page 6),
the overhand loop creates a quick and useful knot. This knot

can be tied in the middle of a rope if a loop is needed there.
It also offers another advantage: If a rope has a worn or

weak point, the point can be incorporated into the loop,
making the rope stronger. But be warned: This knot can jam

when used in rope. Prevent jamming by keeping the knot
from being too heavily loaded, especially shock loaded.
