DETAILED DESCRIPTION
Swinging doors that have transparent panels may be framed or frameless. Framed transparent doors have their transparent panels framed by framing material, such as wood or the like. Framed transparent doors are compatible with conventional lock and hinge hardware, however, the frame material causes a portion of the swinging door not to be transparent and partially blocks items, such as merchandise, being displayed or stored in a retail display unit. Frameless transparent doors do not have the visual obstruction that a framed transparent door has, but is unable to use conventional lock and hinge hardware. Described below is a retail display unit having frameless transparent swing doors with adjustable hinges and an unobtrusive lock.
