The label of the United Brotherhood of Carpenters and Joiners of American identifies products made by UBC members working under union conditions and protected by collective bargaining agreements
The union label appears in one of three forms: a rubber stamp used to place an impression on millwork and manufactured material; a transfer or decal, either color or black-and-white, placed on finished products such as fixtures and furniture; or as an impression by a brass die on products such as boxes and flooring.
