I am a contractor for over 40 years. I have installed hundreds of shower doors. Having never installed a door from VIGO before I of coarse read the manual. a couple of things struct me to be a bit odd. mainly that the rubber seal goes on the door before the hinges. The other was, there where no stainless wood screws for the hinges or the striker jam. rare does one find 3 inch stainless screws in the kit. That being said, why hasn't any other door manufacturer designed a door with the seal being installed before the hinge. This door went in quickly, and I am very impressed with the seal, the ease of the hinge installation. the door works as good as other doors that costs up to 5 times more....  I highly recommend
