Use a Stepladder
When driving down a double extension ladder, the rung of the lower section is closer to the wall that the step you are walking from. This may seem unusual, but this is the correct form of the ladder to be used. So, why stepladder operate this way?
Once in place, the extension starts now some way down the stairs. You must go up the stairs and his feet touch the two sides of the ladder in each step. Coming back down, you get to that point where you need to step to the wall, again in the only the bottom rung of the ladder.
You lean a ladder that extends to the supporting wall with the bottom of the stairs. This is the part that rests on the floor near the wall. Then lift the extending portion of the ladder and secure it to the bottom of the brackets, so that it reaches the required height.
Basics
All double and triple ladders extension work this way all year. The lower part of the ladder is always closer to the wall. Stairs reason work this way is simple in the case of viewing the system placing the ladder against the wall.
Practical System
Imagine standing in front of the wall. Holding the ladder, you have the extension nearest you. To scale up the necessary height, you must first take hold of the extension step and slide up. Basically should slide along the side rails. There are brackets attached to the extension piece allowing you to connect the pieces of the ladder securely at any height you need, basically, by locating brackets and placed on the bottom rungs.
In case you were standing with the extending portion of the stairs near the wall, which would have to come through the steps and lift the side closest to the wall, and the bottom of the scale (more nearby) would get in the way. So that's why you need to take a step closer to the wall while going down a double extension ladder.
