Query: Do Not Buy

I purchased this item through a local retailer. The vinyl/rubber seal was far too tight for the aluminum channel, despite application of soap, petroleum jelly, hot water, and (finally) pliers. Customer support was non-existent, but they get ONE LOUSY STAR for being made in the USA. Except for the installation screws which were made in China and (I swear to God) which broke off at the head in the door sill. Frost King may have other quality products, but this is not one of them.
