Gorter roof hatches with ladders provide practical and safe access to flat roofs for maintenance work as well as access to cooling installations, lift machine rooms, window cleaning installations, solar collectors, and other facilities on rooftops. Roof hatches can be installed on flat roofs with a maximum slope of 30°. Extension ladder Depending on the floor height, the Gorter combination of roof hatch and ladder is available with a single, double or triple extension ladder. The Gorter ladder is supplied as standard with suspension brackets for safe storage when the ladder is not in use. This combination is ideal for infrequent use of the roof hatch. For more frequent use, we recommend a roof hatch with scissor stairs or fixed staircase.
