The Genesis 4 is one of our wall mounted skateboard security racks. This unit is designed to mount to a masonry brick, block or concrete wall surface (mounting hardware not included), and once installed it safely secures up to 4 skateboards. Wall mounting is ideal if concrete floor surfaces aren’t available, or you don’t want to obstruct walkways and sidewalks. In addition to mounting the Genesis 4 at building entrances, you can also mount it at the ideal height (lower for youngers or higher for teens and adults). Maximum efficiency, cost effective, safe and durable! Users must provide their own padlock.
