This is a flat-facing rack, which can either showcase and display the (top) deck, or bottom of the surfboard. This is particularly useful for when trying to fill negative space in a room, or wall gaps up in higher locations, such as over staircases, doorways, and other entryways. This rack can also work as an everyday storage system for your surfboards, as it has a clear rubber padding, which helps keep the surfboard ding free, and water tight. All mounting hardware & instructions are included. We do recommend putting these into studs, but is not necessary, if the drywall anchors are installed correctly. Questions or concerns?
