*Hercules recommends mounting hanger to a wall stud for maximum stability. For non-stud, drywall mounting, please use included plastic screw anchors. Using a drill bit that is slightly smaller than the closed end of the plastic anchor, drill a hole as deep as the anchor (approximately 1.4 inches). Next, tap the anchor into the hole until flush with wall.
