Product review (1 stars): Buyer Beware!
This after market gasket definitely does not work on the Sub Zero door that it it designed for.  Within a few hours of installing it, I had ice building up along the edges of the freezer door. I could feel cold air leaking from the sides and water was condensing along the bottom. The problem is with the magnets, which are too weak to properly seal the door. I had to order a gasket from a Sub Zero distributor which worked perfectly. Not only did I waste a good bit of time replacing the defective gasket twice, but the seller refused to refund the total amount that I was charged after I had returned it to them.
