Abstract

An assembly of wear element (11) for installation on the wearable part of a structure engageable with abrasive material including a relatively elongated base element adapted to be secured to the wearable part and a relatively elongated wear element releasably, reversibly mounted on the base element, each of the elements having longitudinally spaced apart dovetail surfaces (30) in one outstanding wall portion and at least one surface in a second opposed outstanding wall portion positioned between the spaced art dovetail surfaces. A method of designing the dovetail connection through a repeating pattern is also disclosed. <IMAGE>
