Draught Excluder - Set into Door with Plastic Channel?

[jb2]

I have a couple of internal doors at home which I am looking to refurbish.

Both have a ‘channel’ cut into them (above and below the lock), in which sits a plastic extrusion (flush with the edge of the door) which holds brush type draught excluder. Can anyone enlighten me as to what this plastic extrusion is called (if it has a name) and where I can buy some?

Thanks.

smoke strip, which is fitted to fire doors.

I think you live in a flat, or a house with 3 stories or more.

It is available in a few widths.
