Rolling steel door features interlocking slats

CornellCookson Inc.’s EntryDefender Door is a rolling steel door with interlocking slats that compress when it’s in the closed position, create a smooth surface and minimize potential pry points. If an attack persists, the interlocking slats engage further and prevent separation. A reinforced bottom bar and locking system resist lifting force. EntryDefender Door meets U.S. Department of State standards for forced entry and ballistic resistance of structural systems, SD-STD-01.01, Revision G.
