Abstract
An elongated cylinder is essentially comprised of a continuous side wall with a narrow weak wall segment along the length thereof for fracturing by the application of a small force to permit access to the interior of the cylinder along the fractured side wall. The weak side wall segment is in the form of a very thin web section produced by grinding or in a molding operation which may additionally include the filling of the hollowed area of the side wall with a dissimilar material. The article is used for cable placement, varmint protectors for tree trunks, protectors for wire harnesses, protectors for cable splices, and a mold for concrete.
