The first and second edge portions (18,20) are configured for mating engagement at at least two locations, (46,48). The second edge portion (20) includes a generally flat portion arranged to permit attachment of the edge portion to an external support (68) for example by a fastener (66) extending through the flat portion, the mating engagement of the first and second edge portions being such that the generally flat portion and the fastener are covered by the first edge portion (18). |
