Yep! In fact, the instructions that come with the cover do not mention a clamp style. So when you call fantastic vent, they ask for an email and minutes later, they send off a PDF instruction with the location to drill the holes for the screws. That's it!
What I can't understand is why they just don't include the instructions for the clamp style in the instructions that come with the unit. The PDF they sent me, included instructions for the non clamp style. It was just one page longer.
