Clove Hitch

The clove hitch, shown in figure 10-45, is used to secure the suspension lines to the connector links on many parachute assemblies.

You know how to tie the most common knots used in parachute rigging. For even greater security, these knots can be modified to form several other knots. The lock knot is an overhand knot tied adjacent to many other knots. For example, to prevent the square and lock knots or the surgeon's and lock knot from slipping, you tie overhand knots at each end of the thread or cord. Also, the overhand knot can be tied in a series. The same applies to the surgeon's knot. The binder's knot leaves a loose end to form a slip knot, which is used to temporarily tie an excess amount of cord. The AS28A deployment bag uses this type of knot. Also, when you secure the automatic ripcord release's arming knot guide on the automatic seat style parachute, you use a slip knot tied off with a lock knot. The specific knots you use are determined by the engineers who design, test, and establish criteria for the operation and function of parachute assemblies.
