Up-N-Away was the name of a down-sliding bath/ shower door manufactured by Unitspan Architectural Systems, Inc. The bathtub shower doors had vertical tracks instead of horizontal, and closed downward rather than sideways. There were no channel tracks on the side of the bathtub; this enabled the entire side to be free when the doors were open. This design was also to make the side of the tub always clean as well as comfortable to sit on when bathing a child. The down-sliding doors were counterbalanced to be kept up and out of the way for an elegant look, but slid to lower positions for showering. Within the vertical track channels, the lower left and right edge of each sliding door attached to counterweighted ropes with nylon hanger brackets. The downward-closing bath shower doors aimed to solve the disadvantages of conventional, sideways-sliding doors to provide more convenience, relaxation and luxury. They were at first marketed on a store- or factory-to-consumer basis, with do-it-yourself installation required.
