Hold the hook on the concrete block wall. Place a mark on the wall at the screw holes' locations with a pencil. Set the hook aside.
Drill a pilot hole through each mark, using a hammer drill with a masonry bit. Use a masonry bit with the same diameter as the sleeve anchors. Drill the hole a little deeper than the sleeve's length.
Unscrew the mounting screws from the sleeves. Push the sleeves into the pilot hole. Gently tap them in with a hammer until they are flush against the wall.
Put the screw through the hook's screw holes. Line up the screws with the sleeves. Use a screwdriver to tighten the screw into the sleeve.
