Abstract: A mechanical stop is adapted to be mounted onto a rigid bar and includes a single piece conically shaped body having a plurality of inwardly extending projections, each of the inwardly extending projections has a distal end that is contoured to match an outer surface of the bar, the distal ends define an opening, the conically shaped body being adapted to be plastically deformed to a substantially flat shape after being placed onto the rigid bar, the opening having a first dimension, larger than the rigid bar, prior to being plastically deformed and a second dimension, smaller than the rigid bar, after being plastically deformed, such that after the conically shaped body is plastically deformed into a substantially flat shape, the distal ends will frictionally engage the outer surface of the rigid bar to secure the mechanical stop thereon.
