Title: does the job
Review: I purchased this item to climb a 20 ft section of a 12 X 12 roof ((45% pitch) to clean my chimney flues. It is quite sturdy and easy to afix to a ladder. I'm not sure what the advantage is to having two units but I went with one. I guess some redundancy would make a safer unit. If the idea is to hook the ridge to keep the ladder on the roof this does the job quite well.
