Here is UA10775, a new corner cleat connector to suit Unibox TFS (Tension Fabric System) banner frames. This new design features twin steel chevron plates where the screws of the front plate work against the rear plate to fasten the mitre joint; this prevents the screws from coming into direct contact with the aluminium profile and therefore eliminates the possibility of deforming the profile as sometimes seen with the previous single plate connector design. This new twin plate connector creates stronger corner joints and significantly reduces frame twist to promote flatter banner assemblies.
