IMPROVEMENTS RELATING TO CABLE LADDERS |
摘要 |
A cabble ladder system comprises a plurality of parts comprising cable ladder sections and accessories. Each part is made up of spaced side rails connected by support rungs. Adjacent pairs of rail ends form coupling ends so that ladder sections may be connected end to end or to accessories. The rail ends have male and female integral and complementary coupling formations so that the ladder sections and accessories may be coupled without the use, as in conventional or separate connector pieces. |
