Capitol Fireproof Door manufactures the highest quality angle iron and angle iron Z frames. The angle iron frames are designed to save time and money by eliminating the need to replace the existing frame, when the existing frame is out-of-square. Angle iron frames can be used to reverse the swing of the existing door. Doors are pre-hung into the angle iron frame and are installed inside the existing frame. Hinges, locks and other hardware are pre-hung into the angle unit. Angle iron frames are easily leveled, squared and secured permanently into place.

HOW OUR ANGLE IRON & ANGLE IRON Z FRAMES ARE MADE

Angle iron frames are fabricated from three sections of 10 gauge steel flats, which are then bent into L-shaped angles. These sections are mitered and welded together to form a jamb. Our angle iron frames are drilled and tapped to receive hinges and locksets. Counter-sunk screw holes are drilled to accommodate a professional installation.

Angle Z frames utilize the angle frames as described above, adding a
1 3/4 inch, flat trim to the outside of the angle iron frame. This additional trim covers any damaged trim on the existing frame. Counter-sunk screw holes can be drilled into the trim, allowing for easy installation.
