The present disclosure resides in a post, configured to be removably securable in an aperture and having a predetermined first cross-sectional area. The post includes an end portion having an angled face and a wedge, having a complementary angled face arranged against the angled face of the end portion. The wedge is configured to be slidably movable at the end portion to adjust a second cross-sectional area, defined by the wedge and the end portion. The angled face of the wedge is slidably movable relative to the angled face of the end portion to increase the second cross-sectional area relative to the first cross-sectional area to tightly secure the end portion (14) within an aperture. The post may further comprise a mechanism connected to the wedge for slidably moving the angled face of the wedge relative to the angled face of the end portion to increase the second cross-sectional area relative to the first cross-sectional area to tightly secure the end portion within an aperture. The mechanism may be a drawbar having a threaded portion, which is engageable with the wedge whereby rotation of the drawbar causes the wedge to slidably move. |
