The Defender Duopar is a 2-part frame flush steel door system, designed primarily for interior environments which is guaranteed to make an architectural statement every time.

The Duopar delivers the same overall appearance as traditional timber frames and architraves, yet with the added strength and durability of powder coated steel to withstand high usage in
heavy traffic areas.

The clamp-style frame enables fixing at the final stage of construction, after all wet trades have completed, meaning less opportunity for doors to suffer damage from other trades.
