A poster hoarding comprising a cable management system, the cable management system comprising: a plurality of spaced cable guides spaced around a perimeter portion of the poster hoarding, a primary length of cable having a portion that will extend around cable guides around that perimeter when a poster is fitted and taughtened within the hoarding, and a cable tightening mechanism for taughtening the poster when fitted, the cable tightening mechanism comprising: a mechanism by which a cable tensioning part can be pulled, either directly or indirectly, for tightening the primary cable length between the adjacent cable guides, and a geared winder having: a first component for winding up cable slack in that primary length of cable as the cable tensioning part is pulled and a smaller second component from which cable can be unwound as the cable tensioning part is pulled, the relative sizes of the first component and the second smaller component gearing the effect of the pulling such that the length of the primary length of cable that is wound up by the first component as the cable tensioning part is pulled is longer than the length of pull of the cable tensioning part. |
