Manillas graduables de seguridad

Unlike standard adjustable handles, the lever of safety handles is normally disengaged from the clamping element.

Clamping is obtained by pushing the lever to engage the teeth and turning the lever until clamping occurs.

By releasing the lever, the spring disengages the teeth and the handle returns to its rest position, turning freely. In case of accidental shock, the lever is loose and can rotate without affecting clamping.
