Hollow Metal Frame Drywall Profiles & Jamb Depths

Here you can see the standard knockdown drywall hollow metal frame jamb profile. This frame is meant to be installed as a 3 piece knockdown (not welded) unit and is used on interior stud walls after the drywall is up. Notice the double backbends in that the backbend returns back in to the frame. This is a standard feature on drywall hollow metal frames as it helps in sliding it over the drywall. Some standard jamb depths for this type of frame are 5 5/8, 5 7/8, 7 1/8, & 8 1/4 but they are available from 4 3/4" to 9" in double rabbet and from 3 1/4" to 4 5/8" in single rabbet.
