Each hook is continuously adjustable for height in the appropriate stringer (1) and fixable on it via a clamping device (7). Clamping devices are pref. self-locking in relation to the hooks' extension direction. They can consist of levers on the outside of the stringers, with a long and a short arm, and spring. Security is provided against slipping away, and the ladder can always be set at the legally prescribed angle, regardless of height.
