Door Cill (AKA Sill)

Finish off your steel door installation with one of our aluminium door cills. They come powder coated in stock white as standard and ready to cut down to your door width.

Available for all our single and double doors.

Made from extruded aluminium our door cills are suitable for any door install. Powder coated in white as standard, and supplied with black end caps, we can also colour match to your door.
Cills come supplied in standard lengths ready to cut down (1.2m for single doors and 2.2m for double doors). We recommend a bead of silicone between the cill and door threshold. This helps to prevent any potential water ingress.
