Customizable Aluminum Cage Ladder Models
OSHA defines a cage as an enclosure mounted on the side rails of a fixed ladder or fastened to a structure behind the fixed ladder which surrounds the climbing space of the ladder.
A cage ladder is typically used for easy roof and mezzanine access, high or hazardous locations such as areas in close proximity to a roof edge or high-voltage power lines, outdoor advertising, access to interior roof or floor hatches, elevator pits, and for manhole access, and door/wall hatch access.
Note that per OSHA 1910.28(b)(9)(i), new fixed access ladders that extend more than 24 feet (7.3 m) above a lower level and installed on and after November 19, 2018 can no longer use cages. A personal fall arrest system or a ladder safety system must be used.
