The Modum ladder is made of anodized aluminum profiles and is equipped for wall fastening adjacent to a window or balcony. The ladder rungs are hidden inside the profiles. The ladder looks like a downspout or a 3″ x 2″ wide vertical bar on a wall. Release pins (usually at each story) can be positioned to suit the egress location, independent of standard [adder lengths.
When required the release pin is pulled and the ladder unfolds, under its own weight, down to the ground. For high buildings more ladder sections are bolted together to attain the required height. The MODUM ladder also has a offset section for roof-eaves and buttresses.
