Can these be used for vinyl?
I can confirm that these drains are suitable for vinyl floor covering. Please notice that Invisible drain, including it's grate needs to be covered with your finish entirely.
For your information this drain doesn't have clamp - mechanical locking system. It needs to be stuck to the drain with adhesive that connects PVC to stainless steel.
Hope that helps. If you have any questions please let me know.
