Abstract
A ceiling closure above a portable wall (FIG. 6) includes wall panels (14, 15) having upper edges entrained by channels (17, 19) formed of legs (24-27) of a ceiling track. The closure is rendered demountable by having lower panel support channels formed by legs (31, 32) and L-shaped members (33, 34) having a lip (46) with a vertical component interfering with a corresponding lip 47 on a panel support track (36). The L-shaped member is held in place by virtue of the weight of the wall panel which it entrains. One and two panel embodiments are shown; vertical height adjustment (50) is provided.
