Experience the LeiKoSi

A ladder head safety device for single ladders. The LeiKoSi can be mounted to the ladder already at ground level in just a few simple steps. Their bracket can be attached or placed on gutters, window parapets, balconies, and other surfaces to provide additional step safety. With the LeiKoSi, the ladder remains firmly and securely positioned during ascent and descent without slipping sideways or tipping due to the flat angle of attack. The LeiKoSi is suitable for various ladders of the common DIN EN 131/1 type and most types of roofs in the professional and private sector.
