Hollow Metal Frame Profiles & Jamb Depths
Here you can see some of the standard hollow metal frame jamb profiles. This is the conventional type of hollow metal frame meaning it is meant to be welded but it can also be used as a knockdown 3 piece unit and is installed that way at times. The "throat" is the open space in the back of the frame between the backbends. The first dimension is the jamb depth or overall frame size. Jamb depths are available from 3" to 20"...under 4 3/4" jamb depth will be a single rabbet frame.
