摘要
A bolt (2) is passed through a hole drilled in the surface (5) to be protected and secured in place using a washer (4) and nut (3). Both the washer and nut can comprise a non-conductive material. The cone (1) is made from hard rubber, has rounded edges and has a slant of at least 45 deg. A bolt made from a non-conductive material protrudes from the rear or bottom side of the cone.
