best way is to look up the model number on Werner's site. they used to have a decent list of compatible models. having said that, i have the 24 foot variety of this ladder, and it works very nicely.
Its a bit wide to fit from one stair to the next. It may work on the top stair and bottom stair, but not a middle one. That also depends on the height of your risers. Though most should be within the height adjustment.
Model PK70-1 is only designed to fit Werner Ladder. It will not fit a gorilla ladder.
