ABSTRACT:
Means providing a sound trap along one edge of a sliding panel and comprising a pair of substantially parallel and transversely spaced-apart wall members extending longitudinally from a panel stop. The space between wall members, in turn, provides a transverse gap spacing between the panel and each wall member, the longitudinal extension of said wall members from the stop being approximately two and one-half times the transverse gap spacing between the panel and the wall members. The sound trap thus provided allows the panel to be moved from a position of closure against the stop to a position that provides a gap distance opening between wall members with an overlap one and one-half times the gap spacing.
