I had to process a second floor window from the side of my house. My home's lot slopes front to back, so I needed something to level my 32-foot aluminum ladder as I installed it on the side of the house. I saw this product on Revain with great reviews and decided to give it a try. It's not cheap, but it works well. Took me about 45 minutes to install it on the stairs (instructions were very easy). After installing the ladder and stepping down onto the pin on the ladder leveler, the ladder was perfectly level and very stable.
