The MU Series multi-use flush frames meet demands for light- to heavy-duty applications in commercial and industrial buildings. They are ideal for interior and exterior locations, for virtually any wall construction. They feature a jamb profile similar to that of the DW Series frames, but is designed for installation as part of the wall framing sequence.
The MU Series frames may be specified and/or supplied as knock-down (KD) for field assembly before installation or welded for installation as a complete unit. Die-mitered corner connections lock together once the frame is installed. Tab/lock design keeps miter tight.
