Where the distance at the access point between the centerline of the rung and the wall exceeds 12”, a landing platform shall be provided.
Cable for the counter-balanced weights shall be stainless steel and will be contained within the upper side profiles and attached to the base of the movable (descending) section. Counter-balancing weights shall be lead and in sufficient weight to provide neutral weight to the ladder.
When installed parallel to a wall requiring pass-through at the top, extension profiles will provide a minimum pass-through clearance of 42 inches. Where the ladder is required to be installed below the access or starting level, a foldaway extension handle is provided to facilitate access.
