Polylok's Rebar Safety Caps provide the protection you need from protruding rebar at your construction and precast sites. They can be used to protect employees and equipment from exposed rebar, pipe, and anchor bolts. These high-quality caps are brilliant orange for excellent visibility, and fit #3 - #8 rebar. These caps provide greater protection than the Rebar Scratch Caps, but are not intended to prevent impalement.
