Folded ladders (type DSPSD) by properties and purpose correspond to single ladders and symmetric stepladders and consist of two parts that are connected by the rotary knot-holder. The knot-holders construction allows to fold ladder in half transforming it into the symmetric stepladder. And also this knot-holder allows to decompose the product, turning it into a single ladder
The uniqueness and convenience of these folded ladders are that it fulfills two functions at once: a single ladder and stepladder.
On both sides of the ladder to the bowstrings rubber bearings are mounted. Rungs are covered with a spray to prevent slipping workers shoes. The rungs step is 33 sm.
The length of the item as a single ladder is from 3 to 7 m.,
The height of the item as a stepladder is from 1, 5 to 3, 5 m., weigh from 13 to 28 kg.
