Stepladders

Ladder

— stepladders include ladders that can only be used in the open form: two parts of the structure form an angle and are installed on the floor, ground, etc. upward angle. Steps can be located only on one part, or on both. The main advantage of such models is the ability to stand securely without additional support points (walls, poles, etc.), which can be useful, for example, when replacing light bulbs in a spacious room. In addition, steps can be easily used in stepladders. On the other hand, they are less versatile than transformers, weigh more than classic ladders and cannot be applied close to walls.
