The ladder safety device for the gutter from die Höhle der Löwen

Safety on and around the roof is of paramount importance. For this purpose, our ladder protection for the gutter and flat roof is indispensable. Instead of installing multiple ladder hooks, you only have one ladder safety that attaches to the ground on the ladder in minutes.

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.
