Abstract: A safety cap for steel reinforcing bar (“rebar”) has an outer body with an enlarged cap and an elongated stem extending from the cap. A hole in the stem enables the safety cap to fit over the exposed end of a section of rebar. A metal insert, molded within the safety cap, prevents the rebar from punching through the safety cap if a worker were to fall onto the safety cap. The safety cap is retained on the end of the rebar so that it cannot be easily knocked off, by a pair of threaded set screws, or by a magnet positioned within the safety cap over the end of the rebar.
