This is the 21-inch ORB in a painted white finish, 12 gauge steel. Does the same job as the zinc version but with a white coating that blends in better on lighter-colored residential doors. Comes with clevis pin and cotter ring for the installation. If you're replacing one on a white door and don't want bare metal showing, this is the better option. Same rules apply though: confirm the 21-inch length matches your setup before you buy.
