Aluminum 4×5 Multipurpose Folding Ladder (5.7-Meter)

The Aluminum 4×5 Multipurpose Folding Ladder (5.7-Meter) is the largest and most robust model in the articulation ladder family. In trade terms, the “4×5” designation means the ladder consists of 4 hinged sections with 5 rungs per section, giving you a total of 20 rungs.

When fully opened into a straight extension line, it reaches a massive 5.7 meters (18.7 feet). This is a heavy-duty tool favored by commercial painters, roofers, and industrial maintenance workers because it replaces multiple specialized ladders.
