A clean environment enclosure assembly (10) fabricated of a framework comprising a plurality of struts (18, 118, 218) with a plastic sheet (20) suspended between the struts (18, 118, 218) to define an enclosed space (12). A cap (22, 122, 222) is secured to and extends longitudinally along each of the struts (18, 118, 218), the cap (22, 122, 222) presenting a generally planar outer surface (24, 124, 224) and a groove (26, 126, 226) extending longitudinally there along. The sheet (20) is disposed in the groove (26, 126, 226) and overlays the planar surface (24, 124, 224) of the cap (22, 122, 222). A retainer strip (28, 128, 228) is retained in the groove (26, 126, 226) to sandwich the sheet (20) in the groove (26, 126, 226). The retainer strip (28, 128, 228) has an outer face (30, 130, 230) aligned with the outer surface (24, 124, 224) of the cap (22, 122, 222) to present a continuous smooth outer surface from the cap (22, 122, 222) to the strip (28, 128, 228) whereby the sheet (20) is retained in the groove (26, 126, 226) and presents a surface over the sheet (20) as supported by the cap (22, 122, 222) which is substantially continuous over the strip (28, 128, 228). Three embodiments of the cap (22, 122, 222) and the strip (28, 128, 228) are disclosed.
