Measuring tools for stair renovation

[jknut]

Anyone know where to buy a measuring tool for stair renovation?

If you buy ready-made renovation packages, you probably get one of those, but I'm going to use regular parquet on the stairs...

I think it's called a stair compass, there are usually some for sale on Blocket and there were indeed some when I searched just now.

Apparently, he also sells on Tradera.

Ah, that's what they were called. Thanks for the help!
