Simple, Unobtrusive, Easy-to-Install Snowboard Racks. Our Flush Snowboard Mount is the simplest, most minimal rack in the Grassracks product line. Nubbins hold snowboards flush against the wall for maximum visibility and space efficiency. In addition to being incredibly easy to install, it also offers the avid snowboarder a quick Grab-and-Go rack option that let's them mount boards almost anywhere. Installed Dimensions Each mount measures 1.25" in diameter and comes out 0.75" from the wall. The narrower inner "spacer" portion of the nubbin is .85" in diameter and just over 1/2" deep. Mounts can be installed as far apart from each other as needed.
