Yes these work at a cant/lift plate.
However unlike your fixed cant you can set the angle of the cant/lift between 0-8 degrees depending on how you put the halves of the plate together. Then you can rotate that disc to achieve whatever cant/lift you'd like.
The only con is that heavier riders can break them; and there is a small amount of rotation in the interface which is easily solved by putting a piece of rubber between the binding and the cant.
Overall for $20 a cant this is actually a really good deal for these. I think I paid $40 each for a two of these for my daughter to use.
