Easy to installation
1. To install on wood, first insert the stainless steel screw into the plastic hook hole, and use a drill/screwdriver to screw the screw into the beam or wooden board.
2. Installed on the concrete wall, the outdoor light string hook is equipped with a plastic expansion hose. Pre-drill a 0.23 inch hole, put the expansion hose into the hole, then insert the screw into the plastic hook and screw it into the plastic expansion hose.
