Vent seal

Got one today. Same thing. Adhesive strip is on the outside. That make no sense - at least for the ones I've seen.
DMT has has been a real asset and James is a good guy. No idea why he is making them this way.
Its been a while since I had this in my hand but... I think the foam ring can be rolled over/inverted. So the adhesive would land on any one of its 4 sides you wish. Weather strip adhesive is the better plan anyway.
