A system comprising a mounting board 300 and a mountable component wherein the mountable component comprises a cylindrical spigot and a key extending from the spigot and the mounting board has a cavity 310 to receive the mountable component where the cavity 310 has a cylindrical hole 312 to receive the spigot, a first keyway 316 to allow the key to pass fully through the mounting board and a second keyway configured 314 to receive the key such that when the system is mounted to a surface or wall the mountable component is secured in the mounting board 300 by the surface. The spigot may protrude from a cylindrical base which has its own counterbore 320 and provides an interference fit. The length of the spigot may be greater than the cavity 310 so that the key can protrude beyond it. The second keyway 314 may be arranged to prevent rotation of the spigot and the component may be a hook. |
