The rungs are wedged into the stiles with the tenons upright. The steps 5 are then pushed in and secured against falling out of the grooves 2 by means of screws or the like.
It has been shown that this type of construction enables the production of tall ladders which do not become loose even with long-term use and ensure safe and risk-free use.
