ABSTRACT:
A protective cover for the ends of reinforcing bars has a cylindrical tube having upper and lower ends. A cap is mounted on the upper end of the tube and is comprised of a continuous circular wall extending upwardly and outwardly from the upper end of the tube, with a bottom covering the top of the tube. A post extends upwardly from the center of the bottom, and a plurality of spaced rib elements are secured to and extend radially outwardly from the post for connection to the wall. A canopy is secured to the upper edge of the wall and extends slightly downwardly therefrom. The canopy has a circular perimeter which has a downwardly extending circular flange extending therearound. The ribs are tied together by secondary ribs. Friction bars are located within the tube to create friction between the tub and a bar upon which it is mounted.
