Abstract
A screen for anchoring a fastener to a hollow block or brick wall which includes an elongate tubular plastic screen member having first and second opposite ends and a uniform diameter along its length. The first end is formed substantially into a frusto-conical shape that includes at least a portion thereof where the mesh of the screen is closed off. At least one reinforcement member is formed along the length of the elongate screen member that enables the elongate screen member to be inserted within a first aperture formed in a first wall of a hollow block and maintain the desired stiffness of the tubular screen member so that it can extend across an interior of the hollow block for blind insertion into a second aperture formed in a second opposite wall of the hollow block.
