list that looks the same on both sides?

[Dracula]

I need to find a smooth moulding that looks the same on both sides (not a regular door casing), and is at least 260cm long. I found a moulding called "dörromfattning" that would probably be perfect for me except it doesn't come longer than 240cm - as far as I can see. The moulding should be 6-7cm wide. Any tips? (I probably don't want to take the time to hunt down a carpentry shop to produce 6 lengths)

Planed timber is usually available in varying lengths.

Planed timber is usually available in random lengths.

perfect! I can also see that you can get them painted, thumbs up!
