Alumet 3 sectional staircase (9.27 meters)

The versatility of this ladder lies in the fact that it can be used as a sliding ladder of three parts and as a free-standing stepladder (inverted Russian letter "U"). Moreover, the third section is removable, and it can be used separately as a ladder, and the remaining part is a two-section universal ladder. This ladder is by right the most versatile of all ladders, and despite the necessary pairwise overlap of sections both in the "ladder ladder" configuration and in the "stepladder" configuration, which complicates, makes it heavier and therefore makes it more expensive, it is the most popular in terms of marketability due to its exceptional versatility.

The overlap of the second and third sections necessary for strength is provided by a side stop. It is impossible to insert the third section from above through the upper connecting node and bypass this stop. The wall thickness of the HS3 stairs is significantly higher, which increases the feeling of comfort when using these stairs compared to the H3 series.
