Selby's Rising Butt Hinges raise the door over uneven floors or carpeting, eliminating scraping at the bottom. The pitch of the hinge makes the door very easy to close. Both hinges on the door must be pitched the same. The hinges measure 4" long x 3" wide and require a 9/16" clearance. They are handed, lefts and rights, and constructed of .125 gauge cold rolled steel with a brass-plated finish.
