Abstract: A method includes substantially filling with joint sealant first and second kerfs in upper and lower ends, respectively, of a curtain wall member. A locating-and-retaining member of a latching member is embedded in the first kerf's sealant. A receiving-and-retaining member of a first bracket is embedded in the second kerf's sealant, the wall member initially extending upwardly and angularly outwardly relative to the first bracket. The wall member is pivoted inwardly such that an end of a nominally horizontally-disposed portion of the latching member slides along a lower surface of a supporting member of a second bracket causing the latching member to rotate downwardly, compressing foam tape beneath the horizontally-disposed portion. The end of the latching member moves past a locking member until a latch comes into latching engagement with the locking member, the foam tape decompressing and maintaining the latching member in engagement with the lower surface.
