15.3.5 Ferrule Secured Eye

A ferrule secured eye is an eye formed at the end of a sling and secured by a hollow metal ferrule which is passed over and then pressed onto the rope. (See Figure 15.3.5-1 ) This eye may be formed by the ‘turn back loop’ or ‘flemish eye’ method of construction.

A turn back loop is formed by bending the rope to form an eye which is then secured by a ferrule. The strength of the eye is entirely reliant on the ferrule. A flemish eye is formed by opening the strands of the rope in the form of a letter ‘Y’. The open rope tails are laid back into one another meeting the standing rope at the throat of the ‘Y’ thus forming the eye which is secured by a ferrule. In this case the strength of the eye is not solely reliant on the ferrule.
