Gallery Collection GD1SP with Ultra Grain in Medium Oak
Now you can enjoy the beauty of a stained wood door without the
constant maintenance a wooden door requires.

Gallery Collection GD2LP with Ultra Grain in Dark Oak

The Ultra-Grain is actually a steel door, however Clopay went to great lengths to ensure it looks as close to a real stained wooden door as possible. The wood grains run horizontal and vertical, and a coating of stucco texture makes this door look more natural.

Available in Medium & Dark Oak
