Ceco Hollow Metal Frames

The Ceco SU Series hollow metal door frames offer versatility in installation: they can be installed to cap or butt wall. The Ceco hollow metal frames can also be fabricated as three or four piece door frames, borrowed lites, sidelites, or transom frames.
Offered as knock-down (KD) frames with a fire rating up to 90 minutes or welded frames up to 3 hours, these hollow metal frames also meet the Florida Building Code for exterior openings requiring Product Approval.
