ABSTRACT:
A hollow structure for use as an electrical insulator or other similar structure having outwardly disposed flanges extending circumferentially thereabout. The hollow structure includes a hollow member of heat recoverable material positionable about a central insulator core, electrical conduit, fuse or other substrate. The outwardly extending flanges are integrally formed with the hollow member and extend radially therefrom in the dimensionally heat stable state. The hollow member is designed to be expanded to a heat recoverable state for later facile positioning about an appropriate substrate. The hollow member may then be heat recovered about the substrate to become securely positioned thereon. Proper selection of the hollow member as to its dimensionally heat stable inner diameter relative to the inner diameter of the substrate results in control of the orientation of the flanges once the hollow structure has been recovered about the substrate.
