A portable ladder has two stiles interconnected by rungs. The ladder is provided with a stand off device, comprising two stand off arm assemblies, each being telescopically inserted into a receiving space. Each stand off arm assembly has a base part and a stand off arm interconnected by a hinge that allows the stand off arm to be pivoted between a position in alignment with the base part and an angled stand off position. The stand off arm assemblies are each configured such that - in extended position - the hinge is located outside the receiving space with the base part being located within said receiving space, and also such that - in retracted position - the base part, the hinge, as well as at least a portion of the stand off arm are located within the receiving space. |
