2-4. IER + IER-F Extension (Up to Down)
• Like the vertical extension of the IER Frame, use the Joint V and for this purpose, change the Stud location of the JIG F.
• However, in this case, the frames may not be aligned vertically. Accordingly, the vertical and horizontal checks are
mandatory.
• Extended installation is the same as in IER.
• Fasten the Joint V to the Frame to extend.
• Insert the Joint V of the Frame to extend into the previous Frame for exact positioning, and then fasten the screws.
• The vertical gap between Frames after extension is 1 mm.
