ABSTRACT:
A construction for removably retaining a first sheet of glazing adjacent to a second sheet of glazing is disclosed including a fixed frame member adapted to be attached to a glazing cap, and a removable retaining flange connectable to the fixed frame member. The flange-holding side wall of the fixed frame member has a shoulder containing a longitudinal groove adjacent to the flange, and a longitudinal recess having an upper edge and a lower edge including a catch. The retaining flange connects to the fixed frame member by nesting the upper end edge of a vertical leg of the flange into the flange-holding groove of the frame member and locking a lip of the flange member to the catch along the lower edge of the fixed frame recess. When the fixed frame member and the removable retaining flange are connected, the flange of the fixed frame member and the horizontal leg of the removable retaining flange removably brace a first sheet of glazing therebetween.
