Query: lack of versatility

I would have prefered to write a review based upon my use of the Krause Boot Base, but was unable to use it. Apparently, it only works with Krause ladders, something not mentioned in the add. I discovered this fact when I opened the shipped package and read the directions. I tried to use it on a werner, but the pitch is wrong. This one gets shipped back.
