Very well rounded but not for professionals

This ladder is very versatile, I used to when renovating my old apartment. You need eg a ladder for Geocaching is the classic telescopic ladder may be more appropriate, since you can store this compact.
Professionals, so companies and artisans need to secure a conductor with the appropriate seals of approval from TÜV or by the professional association. Such ladders you will but can not buy at this price.
This ladder is but perfectly adequate for the rare use in private area. A visual inspection of the critical points is in any case necessary in each conductor. In this ladder are the hinges with their locks.
