Scroll is the new sliding system, designed and patented by FEDA, to transform bunk staircases into sliding staircases without affecting their safety certification. The Scroll system consists of a trolley and articulated anchor arms, which enable the staircase to be tied to sliding rails. To move the ladder, simply release the braking system by operating the lever on the handrail. The mechanism, prevents accidental movement of the ladder on sloping floors, or in strong gusts of wind. The difference from classic slide rails is that they can also be used on uneven and bumpy floors. Slide rails can be mounted in different positions depending on the wall structure: on the floor, in the lower part of the wall or in the middle and upper part.
