<p>The angle provides a continuous link between two sections of conduit at different angles. The angle accessory includes two flanges (20,30) each of which may be a quarter circle. These provide continuity between the side walls of the two conduit sections. Each flange includes a band (24,34) enable the cover of the conduit to be fastened around the corner. The angle accessory provides a continuous link between two sections of conduit at different angles. Each conduit section has a rectangular u-section, with the two bases (10) of the two u-sections adjoining. The conduits each include a pair of side walls (12,13) whose edges (14,15) are turned to face each other. The angle accessory includes two flanges (20,30) each of which may be a quarter circle. These provide continuity between the side walls of the two conduit sections. Each flange includes a band (24,34) along its curved edge linking the similar edges (14,15) of the conduit side walls. These enable the fastening of a cover section to the conduit, following a defined radius of curvature around the outside of the rectangular joint.</p> |
