Abstract: A turndown pad having a body (10) with panels (102, 104, and 106) that are received in respective openings (82, 84 and 86) of body (10) and also having covers (118 and 120) that are received in openings (88 and 90) of body (10). Panels (102, 104, and 106) are selected from corresponding families of panels with each family of panels defined by a common profile shape and size. The different members of each family of panels (102, 104 and 106) have selected arrangements of holes (110, 112, and 114) respectively so that different combinations of panels provide different combinations of holes (110, 112, and 114).

Abstract: A removable threshold (18) wherein a first sidewall (20) and a second sidewall (22) are joined to a top section (48). The first sidewall (20) has a lower lateral edge (26) and terminal portions (28 and 30) that form radiused corners (68 and 70). The second sidewall (22) has a lower lateral edge (34) and terminal portions (36 and 38) that form radiused corners (76 and 78). Top section (48) has ends (54 and 56) that define radiused edges (84 and 86). Edges (84 and 86) are flush with the edges of terminal portions (28, 30, 36 and 38) and a gasket (62) is secured continuously to threshold (18) along lower lateral edges (26 and 34), terminal portions (28, 30, 36 and 38) and edges (84 and 86) to provide a seal between threshold (18) and a fixture (10).
