If you opt to go for a portable ladder, my recommendation is to avoid the telescoping Extend + Climb. I had one. It failed. I fell. The ladder then quit working; would not extend. The black rings between the rungs came out. I contacted the company. They first said it was not their ladder. I sent them a picture of it with their name on it. They said it was theirs but the warranty no longer covered it. Actually, I had just asked if I could send it in to get repaired. They told me, they do not repair them. They offered to sell me a new one. I'll pass. One fall is enough. Be careful with this product !
