Excellent ladder very stable


I am on the 2nd ladder, I wore the first one out. I have used it in my business for the last 15 years. I have done things on this ladder I would never dream of doing on any other ladder. I have found it to be very stable. I have used to ladder as a bridge to get back into areas by climbing up one side and down the other to get into a tight corner. It is heavier the other ladders, but for the stability it is well worth it. When i have worn out parts they have been very quick to send out replacement parts. I will buy a third when the time comes.
