Steel Flush Frame

The F Series three-sided flush frames meet requirements for light- to maximum duty applications for interior and exterior locations in commercial and industrial buildings. They are designed for installation as part of the wall framing sequence and may be specified and supplied as knock-down (KD) for field assembly prior to installation or welded for installation as a complete unit.

Sometimes referred to as masonry frames, F Series frames are typically butted to CMU block using wire or Masonry-T anchors as the wall is being built, or using EMA (existing masonry) anchors for concrete or CMU block after the wall is up.

F Series is the most common series for welded corners to get a cleaner look without a die miter seam. Because you can weld F Series, these frames are also popular in stud wall applications, and stud anchors can be specified. Here the frame must be installed as part of the wall framing sequence (as the wall is being built so the studs can be pushed up into the frame and anchored). While acceptable, most drywall applications utilize compression anchors in DW and K Series frames so that installation can occur in the rough opening after the wall is completely finished. If a backbend return is desired to make pushing the drywall in between the studs and the frame, use MU Series frames.
