The invention relates to a post (129) for a shaft scaffold (102) of an elevator system (103), said post comprising at least two supports (236) on its exterior sides which extend approximately parallel to the longitudinal axis of the shaft scaffold (102), to which at least one traverse strut (201) can be connected. The aim of the invention is to produce and design the device, the post and/or the associated connecting elements of the post for a shaft scaffold of an elevator system in such a cost-effective manner that an easy and rapid assembly of a shaft scaffold can be ensured. According to the invention, said aim is achieved by providing, apart from the two supports (236), at least one additional support (236) for the connection of at least one guide element (220).
