Abstract: A thread protector has a toroidal body of elastomer with a bore to accept a pipe end and a metal band and clamp arrangement extending around its periphery. The body is cut through one side to allow the body to expand peripherally. The bore accepts the end of a pipe with threads to be protected when the periphery is expanded and grips the pipe with the bore when the clamp closes the cut and shrinks the bore. To increase unit loading to force more elastomer of the body into thread grooves the bore has projections for gripping pads, or is recessed radially to produce gripping pads. The pads, which may be replaceably attached, reduced area increases deformity under clamping pressure and increases the force required to dislodge the protector from threads. The metal band is removable from an open peripheral groove or an optional arcuate tunnel partially encircling the pad body.

Abstract: An end protector for a reinforcing bar has a one piece support and a cushion. The support has a cylindrically-shaped receptacle with two arms extending outwardly therefrom and two longitudinal slots that are generally opposed to one another along either side of the receptacle. The arms hold the cushion in position on a side of said receptacle opposite to the reinforcing bar. When an external force is exerted on the cushion, at least part of the force is transferred through said arms to said receptacle, thereby causing the slots to narrow and the receptacle to further tighten onto said rebar. When the external force is removed, the support returns to its initial position. Thus, when no external force is exerted onto the protector, it can be easily installed or removed from an end of the reinforcing bar.
