Sometimes you don't want the entire door replaced! Why not simply buy the parts you need.
To select the right frame size (this is the outer section of the door), confirm the measurements of your existing door using the chart below.
Dimensions of Complete Door: 400mm
Flap width: 285mm
Flap Height: 245mm
The frame is a single piece and does not include the ring on the other side of the door, which may also need to be replaced, and is available separately.
