Their products have been redesigned with consumers in mind. They have changed Classic Design Standard Single Barn Door Hardware Kit to have fewer pieces so installation is now more simple and quick. All tracks below 8' are now using the American Standard spacing (16") and are one single track now instead of being composed of smaller tracks. All tracks now have additional holes at the end of both sides for expanding the track size. For tracks 8' and above, connecting tracks is now simple and quick, using a junction plate at the ends of the tracks to connect. Features I recommend 40" or 42" wide doors. See More
