The present invention provides an extendable telescoping boom having one or more telescoping sections which nest inside one another allowing the boom to extend and retract. Along the surfaces of the boom sections are one or more sunken pockets in the surface of the boom sections which contain one or more wear pads attached within one or more sunken pockets allowing the multiple boom sections to slide linearly one inside the other with a reduced gap between the boom sections. A method of manufacturing an extendable telescoping boom assembly is also provided.
