Abstract: A device (100) for securing a post (105) comprises a central portion (110) defining an aperture (115) therethrough configured to engage the post (105) and two or more support members (120) extending outwardly from the central portion (110). Each support member (120) comprises a first portion (125) and a second portion (130), the first and second portions (125, 130) each comprising at least one support element (135, 140) configured to extend towards and further engage the post (105). The second portion (130) is configured to penetrate a post-mounting surface (132) in a substantially longitudinal direction relative to the post (105), thereby securing the post (105) with respect to shear forces acting on the post (105) in a direction substantially perpendicular to the longitudinal direction.
