what is it called? U-shaped edge piece for opening in wall of tongue and groove/panel

[kaktusen]

I need some meters of wood of the type shown in the pictures.

Is there a term for it? So I can search for a store that sells it. It is U-shaped to function as an "edge piece" for an opening in an interior wall of tongue and groove/panel in a garden shed. The extra small milled channel in the middle is not needed for my purpose.

It is simply called u-list

It is probably specially cut to grip the wood that sits against the opening, probably not available as a standard purchase, you can take a rule, cut it to the correct wall measurement, and use others as lining.

It's simply called a u-list, something like:

Thanks, the linked variant has too narrow a groove for my purpose. I searched for U-list in some other building stores but got no hits. Perhaps there is another term?

bauhaus, byggmax, xl bygg: no hits
k-rauta: only metal lists

It is probably specially cut to grip the wood that is against the opening, probably not available as a standard purchase, but you can take a beam, saw to the correct wall dimension and use others as lining

Yes, in the worst case I will have to build a U-shape as you describe, but I prefer to buy a ready-made piece. Another option is to mill out a channel from a piece, but I don't have the tools for that.

I suspect you have a log-constructed "friggebod." The small notch in the middle is probably meant to grip an end joint. If these assumptions are correct, you need to consider what is most important for achieving a stable wall ending. Probably a strip with the width of the wall and a notch for the end joint is the best way to stabilize the wall. You can make a strip with a notch and end joint yourself using a hand router. If you don't own one, you can probably rent it. A bit fiddly but probably important.

I suspect you have a log-cabin type shed. The small groove in the middle is probably meant to grip an edge joint.

Thanks for the reply. That's somewhat correct, I think, but at the opening inside the cabin where I plan to use it, there’s no small edge that matches the smaller groove. There it only serves an aesthetic purpose. However, I believe the same pieces can be used as railing/capping on top of half-height jointed walls in the veranda part of other cabin variants. In that case, the edge of the top joint clicks into the smaller groove.
