Suitable for use with roof hatch
Gorter vertical ladders / wall ladders can be combined with a Gorter RHT aluminium roof hatch with a minimum opening of 900 x 900 mm (RHT9090).
If a vertical or cage ladder is placed against an outside wall, there should be a safe landing on the roof. This implies, among other things, that the cage and ladder uprights are extended by 1,100 mm. Gorter will be pleased to provide advice on the implementation and can create safe transition platforms where necessary.
